== '''Turn the printer on but the screen is black''' ==
 +
 
 +
<big>Warning: Never install or unplug anything on a printer while it’s being powered!</big>
 +
 
 +
 
 +
(a)Check if the power supply is working normally. The red indicator on the switch should be light. And also check the fuse in the little black box, it should be complete without burns. Please measure the output voltage, which should be around 24 Volts.
 +
 
 +
[[File:W41.png]]
 +
 
 +
(b)Check if the control board is working normally. There’re two green LEDs and one red LED working as the picture shown below. Measure the input voltage of the control board, it should be around 24 Volts.
 +
 
 +
[[File:W42.png]]
 +
 
 +
(c)Make sure the screen is connected properly.
 +
 
 +
== '''The extruder keeps making a click sound''' ==
 +
 
 +
(a)Decrease the print speed. If the print speed is too fast, the extruder will push the filament too quickly. Filament may not have enough time to melt and even clog in the nozzle. A clogged nozzle will then exert pressure back on the extruder, resulting in clicking. For PLA, our recommended print speed is under 250 mm/s.
 +
 
 +
 
 +
(b)Increase the print temperature. If the temperature is too low, it will not melt the filament properly. This can also clog the nozzle. As the extruder is no longer able to push the filament ahead, it starts “slipping”.
 +
 
 +
 
 +
(c)Check the pneumatic fittings. A loose coupling could therefore allow molten filament to leak into a gap between the tube and the nozzle. This will restrict the flow of the filament, causing the extruder keep clicking.
 +
 
 +
[[File:W43.png]]
 +
 
 +
(d)Change the extruder gear. After many hours of use, the teeth of the extruder may eventually wear out. Thus, it can no longer hold the filament, leading to filament slipping in the extruder.
 +
 
 +
 
 +
(e)A low-tension extruder arm bar. If spring tension is too low, the extruder gear will not properly grip the filament. This leads to filament grinding.
 +
 
 +
 
 +
(f)Check if the grub screw on the extruder gear. If the grub screw is loose, the gears will fail to grab the filament.
 +
 
 +
[[File:W35.png]]
 +
 
 +
== '''Nothing is printing''' ==
 +
 
 +
(a)Nozzle is too close to the hotbed
 +
 
 +
Even though the extruder is working but no filament is depositing on the hotbed, Check if the nozzle is too close to the hotbed. Adjust the Z-offset value slightly will help.
 +
 
 +
 
 +
(b)Print temperature is too low
 +
 
 +
Some filament needs more higher temperature, manually feed the filament, if it can not be extruded, please try increase the print temperature.
 +
 
 +
 
 +
(c)The extruder is not working
 +
 
 +
Check if the grub screw on the extruder gear. If the grub screw is loose, the gears will fail to grab the filament when feeding into the hotend. Also check if the extruder motor is connected properly.
 +
 
 +
 
 +
 
 +
== '''Mintemp error''' ==
 +
 
 +
The Mintemp error in 3D printers is a design feature within your firmware for safety in regard to temperature. When below a set temperature, the heater will be switched off due to possibly having a broken thermistor wire. It can be observed a negative the temperature on the LCD screen.
 +
 
 +
 
 +
Check if the hot end connector and thermistor are connected properly as the pictures below. Check the hotend cables and thermistor, make sure they’re not broken or burn out.

You can test the thermistor by a multimeter. If it fails to read the resistance, then the wire is broken. At room temperature, it should be 80 kΩ - 125 kΩ.
 +
Or apply heat to the thermistor with a heater, blow-dryer or other heating device.
 +
 
 +
 
 +
The resistance should decline steadily in seconds if it works. If not, replace it.
 +
 
 +
 
 +
Another common reason behind getting the MINTEMP error is from being in a cold environment, especially in winter months. Your 3D printer is designed to have a minimum temperature that it can operate in as a safety feature.

== '''Automatic leveling failed''' ==
 +
 
 +
(a)3D Touch is abnormal
 +
 
 +
Check if the 3D Touch cables are connected properly. You can use the “Test” function to check if the 3D Touch is working normally.
 +
 
 +
[[File:W45.png]]
 +
 
 +
(b)Homing failed
 +
 
 +
Check the X, Y and Z axes end stops, make sure they’re all connected properly. Note the photoelectric end stops on the Y and Z axes, which normally have a blue signal light. You can home the X, Y and Z axes one by one to check which axis is faulty.
 +
 
 +
[[File:W46.png]]
 +
 
 +
Also check the X and Y axes closed loop motor connections.
 +
 
 +
[[File:W50.png]]
 +
 
 +
(c)The first layer is messy
 +
 
 +
Please clean the hotbed before printing, this will help to get a good adhesion. We recommend a thicker first layer, 0.3 mm is good. If these’re not helpful, please try to adjust the Z-offset. What’s more, you can try adjust the hotbed temperature, for example, the Geeetech wood PLA needs a lower hotbed temperature but PETG needs higher.
 +
 
 +
== '''Spring steel sheet problem''' ==
 +
 
 +
The spring steel sheet is flexible and easy for part removal. But keep in mind that prints are easy to remove after the plate cools down. Don’t try to forcefully remove the object when the sheet is still hot. We do not suggest you use the adhesive on the sheet, because the adhesive is difficult to clean up and may have an opposite effect.
 +
 
 +
If there’re leftover residue on the sheet, preheat the hotbed to 80 degrees to make the plastic soft. Then use the wet cloth wiping the plate and gently scrap the residue off.
 +
 
 +
A dirty bed will cause poor first layer adhesion. You need to remove the dirt, leftover residue or oil from the bed surface. Isopropyl alcohol (IPA) 90%+ will help to degrease the platform.
 +
 
 +
 
 +
== '''Filament sensor''' ==
 +
 
 +
If there’s error on the screen prompts like “Change Filament” even filament has been uploaded, maybe the sensor is broken. You can test it by a multimeter.
 +
 
 +
Remember load a small piece of filament through the sensor before test. By touching each of the measurement leads of the multimeter to the two pins of the sensor, a signal (beep or 0 value on the multimeter screen) will indicate that the component is intact and therefore, should work.
 +
 
 +
[[File:W1.png]]
 +
 
 +
=='''Nozzle discharge abnormality'''==
 +
 
 +
1. Filament is knotted and stuck, and the feeding is not smooth.
 +
 
 +
2. The nozzle temperature is too low and does not reach the required melting temperature of filament.
 +
 
 +
3. There is carbonization residue in the nozzle, please replace the spare nozzle.
 +
 
 +
4. The heat dissipation of the nozzle is insufficient, resulting in the filament in the upper part of the pipe melting in advance, and the extrusion force is insufficient. Please check whether the cooling fan works normally.
 +
 
 +
5. The printing speed of model slices is too fast, and the nozzle extrusion speed cannot keep up with it. Please reduce the speed.
 +
 
 +
6. If the nozzle extrusion is not smooth due to scraping, please use the nozzle cleaner to dredge the nozzle after preheating.
 +
 
 +
 
 +
=='''The extruder gear slips and makes abnormal noise'''==
 +
 
 +
1. Nozzle blocking, refer to the "nozzle discharge abnormality" treatment.
 +
 
 +
2. Check whether the friction force of extruder gear to filament is enough, please clean up the gear residue.
 +
 
 +
 
 +
=='''First layer abnormal'''==
 +
 
 +
1. The first layer does not stick: the nozzle is too far away from the hot bed, please adjust the hotbed leveling again.
 +
 
 +
2. The first layer is not discharging, and the hot bed has scratches: the nozzle is too close to the hot bed, which is easy to damage the nozzle. Please level it again and check whether the discharging of the nozzle is normal.
 +
 
 +
 
 +
=='''Layer shift'''==
 +
 
 +
1. The printing speed of model slices is too fast, please reduce the printing speed.
 +
 
 +
2. The belt of X axis or Y axis is too loose, please adjust the belt tightness.
 +
 
 +
3. X axis or Y axis synchronization wheel is not secured, please adjust the machine meter on the synchronization wheel.
 +
 
 +
 
 +
=='''X/Y axis Closed-loop Control Abnormality'''==
 +
 
 +
During the using of THUNDER, if the X-axis or Y-axis is stuck in the process of movement, it may be caused by the following two reasons after excluding the non-pulley structure and improper connection of wiring:
 +
 
 +
1. The X-axis motor or Y-axis closed-loop control sensor is not calibrated or the calibration parameters fail, the closed-loop control sensor of the corresponding axis needs to be re-calibrated.
 +
 
 +
2.The magnet of the closed-loop control unit of the X-axis motor or Y-axis motor is loose or falls off. The magnet needs to be fixed on the motor shaft with glue again.

How to use Smarttokits

Smatto Kits


In order to enable users to better use and adjust Thunder, we have opened the parameters of the core algorithm of Thunder firmware. Users can adjust the parameters of Thunder according to the usage scenarios and requirements to obtain better print quality. It should be noted that Thunder may also get worse print quality due to the adjusting of some parameters.


User mode requires using the Smartto Kits tool and modifying parameters via USB. Users can also export and share their configuration parameters with other users, or import parameters from other users into Thunder.

Here we provide a download link for the Smart Kits tool that you can download and use it by yourself. Here is how to use Smartto Kits.

1.Install the CH340 driver (the TF card attached with the printer has the driver file, or you can search and download the CH340 driver from the Internet).

2.Plug the B-type interface of the USB cable into THUNDER and the other end into your computer.

Smartto Kits Basic Menu Description


Thunder10.jpg


Import: Import Thunder configuration parameters

Export: Exports Thunder configuration parameters

Get Status: Reads the current parameters of Thunder

Use Default: Use the factory Default parameter of Thunder (print mode)

Save: The saved parameter is valid only for this time. The parameter becomes invalid after restart Thunder

Apply: Write the modified parameters to the Thunder Flash memory


Thunder UI parameters explanation Fastprint Mode

You can choose Normal mode, Fast mode, Crazy mode, User mode and Slow mode. Except User mode, all the parameters are preset by the printer. The user cannot edit them.

•First Layer Mode

Set the printing mode of the first layer (currently the default is 0.3mm height, all below is considered as the first layer). For some filament, high speed switching of the first layer will lead to poor adhesion of filament to the hot bed. It is necessary to lower the acceleration and deceleration so that the first layer can be enabled to print stably. The default mode is S4.

•Curve Mode

The default value ranges from 0 to 7. Different parameters affect the speed of the trajectory of the model. The speed of the trajectory decreases when the parameter ranges from 0 to 7, and the default value is 6.

S0~S3: the motion trajectory basically keeps running at high speed, and the speed decreases step by step; Suitable for some models, easy to cause model edge bulge; Enabling these modes will restrict the implementation of some algorithms, resulting in invalid parameter Settings.

S4~S7: The motion trajectory is slowed down to different degrees by coupling processing of multiple algorithms. The larger the parameter, the flatter the printing. It is generally recommended to use S5~S7, S4 in some models easy to cause jitter.

•Corner Line Threshold

Represents the length threshold of a small consecutive line segment at the junction of a corner (unit: mm). Line segments less than this value will have special treatment at the corner to prevent overshooting; Choosing different thresholds can well reduce the strong jitter problem caused by continuous short line segments (about 0.4~1.5mm line segments connected into a curved surface, circle or ellipse) and small angles at high speed; The parameter range is [0.01,100].

•Max Junction

Indicates the maximum startup speed when the corner between two commands is at a right Angle. When Mode 4-7 is selected in Curve Mode, the motion speed curve generated by the algorithm will shift upward or downward according to this value. The larger the parameter is, the faster the overall velocity is. Generally, the set value is between [6,40], and the unit is mm/s.

•Dynamic Acceleration(Minimum)

Represents the minimum preset acceleration of the printer, and the preset acceleration greater than this will be dynamically adjusted according to the bending degree of the movement trajectory. The value ranges from [500, 9000]. The value 9000 indicates that this function is disabled. Suitable for models that requires stable printing process.

•X/Y Frequency

Max Frequency (Hz) represents the upper limit of oscillation Frequency of X/Y axis. When the motion part set in the model moves back and forth, movements higher than this Frequency will decelerate accordingly. The frequency unit is Hz. This will effectively reduce the printer shock caused by printing small infill models. The frequency is limited to [0, 200].

Minimum Speed (%) Specifies the Minimum Speed factor that limits the Minimum amount of deceleration. Parameter range [0, 100].

•Acceleration

Compute Mode: If you choose Acceleration, adjusting the parameters of Print Acceleration and Travel Acceleration is valid. If you choose Total Acceleration , adjusting the Print Acceleration and Travel Acceleration is invalid.

Print Acceleration: Represents the default acceleration, the unit is mm/s2.

Travel Acceleration: Represents the acceleration of empty driving, the unit is mm/s2.

•Jerk

Jerk represents the starting speed of X/Y/E, where the maximum starting speed of X/Y/E can be set.

•Extruder

Max_advance_speed:Specify the upper limit of the pressure adjustment speed (LINE ADVANCE); Prevent the extruder from producing strong noise and abnormal discharge due to high speed; The parameter range is [0.1,35]; The default value is 16mm/s. Too high speed will cause extruder vibration, too low will cause printing acceleration reduction.

Advance K: Represents the K value of pressure regulation. The larger the value, the more extruder retraction will be. Generally, the remote extruder is set between [0.05,0.8], and the short-range extruder is set between [0.01,0.2].

How to print with Cura

Thunder printing speed can reach 300mm/s. In order to ensure the printing quality even in high speed, the correct setting of slicing parameters is essential. We recommend the Cura slicing software and provide Thunder configuration file for Cura slicing software on this page.

Cura slicing software download link: https://github.com/Ultimaker/Cura


We offered 2 configuration files for Thunder, see below about importing file to Cura software.

Turn the printer on but the screen is black

Warning: Never install or unplug anything on a printer while it’s being powered!


(a)Check if the power supply is working normally. The red indicator on the switch should be light. And also check the fuse in the little black box, it should be complete without burns. Please measure the output voltage, which should be around 24 Volts.

W41.png

(b)Check if the control board is working normally. There’re two green LEDs and one red LED working as the picture shown below. Measure the input voltage of the control board, it should be around 24 Volts.

W42.png

(c)Make sure the screen is connected properly.

The extruder keeps making a click sound

(a)Decrease the print speed. If the print speed is too fast, the extruder will push the filament too quickly. Filament may not have enough time to melt and even clog in the nozzle. A clogged nozzle will then exert pressure back on the extruder, resulting in clicking. For PLA, our recommended print speed is under 250 mm/s.


(b)Increase the print temperature. If the temperature is too low, it will not melt the filament properly. This can also clog the nozzle. As the extruder is no longer able to push the filament ahead, it starts “slipping”.


(c)Check the pneumatic fittings. A loose coupling could therefore allow molten filament to leak into a gap between the tube and the nozzle. This will restrict the flow of the filament, causing the extruder keep clicking.

W43.png

(d)Change the extruder gear. After many hours of use, the teeth of the extruder may eventually wear out. Thus, it can no longer hold the filament, leading to filament slipping in the extruder.


(e)A low-tension extruder arm bar. If spring tension is too low, the extruder gear will not properly grip the filament. This leads to filament grinding.


(f)Check if the grub screw on the extruder gear. If the grub screw is loose, the gears will fail to grab the filament.

W35.png

Nothing is printing

(a)Nozzle is too close to the hotbed

Even though the extruder is working but no filament is depositing on the hotbed, Check if the nozzle is too close to the hotbed. Adjust the Z-offset value slightly will help.


(b)Print temperature is too low

Some filament needs more higher temperature, manually feed the filament, if it can not be extruded, please try increase the print temperature.


(c)The extruder is not working

Check if the grub screw on the extruder gear. If the grub screw is loose, the gears will fail to grab the filament when feeding into the hotend. Also check if the extruder motor is connected properly.


Mintemp error

The Mintemp error in 3D printers is a design feature within your firmware for safety in regard to temperature. When below a set temperature, the heater will be switched off due to possibly having a broken thermistor wire. It can be observed a negative the temperature on the LCD screen.


Check if the hot end connector and thermistor are connected properly as the pictures below. Check the hotend cables and thermistor, make sure they’re not broken or burn out.

You can test the thermistor by a multimeter. If it fails to read the resistance, then the wire is broken. At room temperature, it should be 80 kΩ - 125 kΩ. Or apply heat to the thermistor with a heater, blow-dryer or other heating device.


The resistance should decline steadily in seconds if it works. If not, replace it.


Another common reason behind getting the MINTEMP error is from being in a cold environment, especially in winter months. Your 3D printer is designed to have a minimum temperature that it can operate in as a safety feature.

Automatic leveling failed

(a)3D Touch is abnormal

Check if the 3D Touch cables are connected properly. You can use the “Test” function to check if the 3D Touch is working normally.

(b)Homing failed

Check the X, Y and Z axes end stops, make sure they’re all connected properly. Note the photoelectric end stops on the Y and Z axes, which normally have a blue signal light. You can home the X, Y and Z axes one by one to check which axis is faulty.

(c)The first layer is messy

Please clean the hotbed before printing, this will help to get a good adhesion. We recommend a thicker first layer, 0.3 mm is good. If these’re not helpful, please try to adjust the Z-offset. What’s more, you can try adjust the hotbed temperature, for example, the Geeetech wood PLA needs a lower hotbed temperature but PETG needs higher.

Spring steel sheet problem

The spring steel sheet is flexible and easy for part removal. But keep in mind that prints are easy to remove after the plate cools down. Don’t try to forcefully remove the object when the sheet is still hot. We do not suggest you use the adhesive on the sheet, because the adhesive is difficult to clean up and may have an opposite effect.

If there’re leftover residue on the sheet, preheat the hotbed to 80 degrees to make the plastic soft. Then use the wet cloth wiping the plate and gently scrap the residue off.

A dirty bed will cause poor first layer adhesion. You need to remove the dirt, leftover residue or oil from the bed surface. Isopropyl alcohol (IPA) 90%+ will help to degrease the platform.


Filament sensor

If there’s error on the screen prompts like “Change Filament” even filament has been uploaded, maybe the sensor is broken. You can test it by a multimeter.

Remember load a small piece of filament through the sensor before test. By touching each of the measurement leads of the multimeter to the two pins of the sensor, a signal (beep or 0 value on the multimeter screen) will indicate that the component is intact and therefore, should work.

Nozzle discharge abnormality

1. Filament is knotted and stuck, and the feeding is not smooth.

2. The nozzle temperature is too low and does not reach the required melting temperature of filament.

3. There is carbonization residue in the nozzle, please replace the spare nozzle.

4. The heat dissipation of the nozzle is insufficient, resulting in the filament in the upper part of the pipe melting in advance, and the extrusion force is insufficient. Please check whether the cooling fan works normally.

5. The printing speed of model slices is too fast, and the nozzle extrusion speed cannot keep up with it. Please reduce the speed.

6. If the nozzle extrusion is not smooth due to scraping, please use the nozzle cleaner to dredge the nozzle after preheating.


The extruder gear slips and makes abnormal noise

1. Nozzle blocking, refer to the "nozzle discharge abnormality" treatment.

2. Check whether the friction force of extruder gear to filament is enough, please clean up the gear residue.


First layer abnormal

1. The first layer does not stick: the nozzle is too far away from the hot bed, please adjust the hotbed leveling again.

2. The first layer is not discharging, and the hot bed has scratches: the nozzle is too close to the hot bed, which is easy to damage the nozzle. Please level it again and check whether the discharging of the nozzle is normal.


Layer shift

1. The printing speed of model slices is too fast, please reduce the printing speed.

2. The belt of X axis or Y axis is too loose, please adjust the belt tightness.

3. X axis or Y axis synchronization wheel is not secured, please adjust the machine meter on the synchronization wheel.


X/Y axis Closed-loop Control Abnormality

During the using of THUNDER, if the X-axis or Y-axis is stuck in the process of movement, it may be caused by the following two reasons after excluding the non-pulley structure and improper connection of wiring:

1. The X-axis motor or Y-axis closed-loop control sensor is not calibrated or the calibration parameters fail, the closed-loop control sensor of the corresponding axis needs to be re-calibrated.

2.The magnet of the closed-loop control unit of the X-axis motor or Y-axis motor is loose or falls off. The magnet needs to be fixed on the motor shaft with glue again.

=='Filament'==

Does Thunder require high-speed PLA filament to achieve high-speed printing?

No, Thunder is designed to achieve high-speed printing with ordinary PLA filaments, so Thunder can achieve high-speed printing with ordinary PLA filaments.

HS-PLA Series Filament "Speed-Temperature" Parameter Settings for Reference

HS-PLA is Geeetech's latest high-speed printing filament. By adjusting the melting point, melting index, glass transition temperature of raw materials and optimizing the production process, Geeetech enables HS-PLA to have stronger fluidity, smoother discharge, faster curing and forming speed and is not easy to deform under the melting condition. Compared with ordinary PLA, HS-pla has the advantages of faster printing speed, higher printing quality and more delicate model surface, which can better meet the high performance requirements of high-speed 3D printers for filament.


Due to the differences in slicing parameters, environment and printers, the following table is for reference only.

X/Y Axis Closed-loop Motor Calibration and Abnormality Elimination

Thunder 018.jpg


X and Y axis motor are all closed-loop controlled, and the closed-loop control sensors on the motors have been calibrated before delivery. Do not remove the closed-loop control sensor if the X-axis and Y-axis are not abnormal. Otherwise it will cause the calibration parameters of the closed-loop control sensor on the X-axis and Y-axis to be offset, resulting in the X-axis or Y-axis stuttering or abnormal jitter during the printing process.


On the screen menu, we provide the X-axis and Y-axis closed-loop control sensor calibration function. The specific path is "Operate" → "Motion". In the "Motion" menu, you can see two buttons "X Encoder Cal" and "Y Encoder Cal". They are X-axis and Y-axis closed-loop control sensor calibration buttons respectively. The specific calibration methods are as follows:

X axis: First, ensure that the hot end can move smoothly on the X axis, and then move the hot end to the middle of the X axis. Then click the "X Encoder Cal" button, and the control panel will pop up to prompt whether to confirm the calibration of the X axis closed-loop control sensor. Choose "YES", and the hot end will move first to the right and then to the left. When the hot end stops, the calibration is complete, and the UI will prompt that the calibration is complete.

Y axis: First, ensure that the hot bed can move smoothly on the Y-axis. Then, move the hot bed to the middle position of the Y-axis, and then click "Y Encoder Cal" button. The control panel will pop up to prompt whether to confirm the calibration of the Y-axis closed-loop control sensor. When the hot end stops, the calibration is complete, and the UI will prompt that the calibration is complete.
