Printer Introduction

Alkaid is made in black and white with 6.08 "2K resolution, enabling X/Y accuracy up to 0.05mm. Alkaid's z axis uses a high-cost linear guide rail, which has the characteristics of high rigidity, high load, automatic self-aligning, absorbing assembly errors, etc., which can effectively improve the overall printing quality of 3D printers. A new generation of matrix light source, using 15 pieces of high-light power quartz lamp beads, with professional optical materials made of matrix lenses, so that ultraviolet irradiation on the LCD screen more uniform, higher intensity, effectively improve the printing speed and accuracy.The rugged Alkaid innovates by integrating UV lamp beads on the aluminum substrate at the bottom of the machine, allowing for greater heat dissipation area. With the cooling fan, it can effectively reduce the temperature of the lamp board and extend the service life of the UV lamp beads. Alkaid is easy to operate and affordable, making it ideal for beginners and amateurs. In addition, geeetech is able to provide ODM and OEM custom design and manufacturing.

Printer Maintenance

How to replace UV light

The following is a video tutorial to replace the UV lamp, please follow the tutorial. replace UV light

How to replace motherboard

The following is a video tutorial to replace the motherboard, please follow the tutorial. replace motherboard purchase link motherboard

How to replace FEP film

First please prepare a sheet of FEP film, which can be purchased from the link below. FEP film

Unscrew the screws in the picture below.

Install the new FEP film, take care not to exhaust the screws when screwing, just make sure to screw well. Because too much force will cause damage to the pressure plate fixing FEP film, as shown in the figure below.

How to replace power supply

Below is the power supply, if the light on the power supply is not bright, it needs to be replaced. Please contact technical support.

How to replace Print screen

Please click the exposure test button in the image below to perform the exposure test.

Please check whether the print screen under the exposure test is as shown below. If the effect is not good, you need to replace the print screen.

Print screen purchase link Print screen

Unscrew the screen and replace it with a new screen.

Trouble Shooting

The pressure plate is damaged

The pressure plate is broken as shown in the figure below. The pressure plate purchase link The pressure plate

The rupture of the pressure plate will cause the resin in the resin box to leak onto the printing screen, and the resin is corrosive and likely to corrode the printing screen. When replacing the FEP film, please be careful not to use too much force, just make sure that the screw is screwed properly, if too much force will cause the pressure plate to crack.

Print screen damage

Please refer to the replacement print screen above. If the resin in the resin box leaks onto the printing screen, the resin is corrosive and is likely to corrode the printing screen.

Resin non-stick forming platform

1.Please re-level, be careful not to tighten all screws at once after zero, which will cause the forming platform to skew. Turn the four screws in turn until they are half loose and half tight, and then tighten all screws after ensuring that they are level. Try printing another model after leveling it.

If the hot bed is still non-stick, please perform an exposure test to check that the print screen and UV etc. can work properly.

2.If the support is not added enough, it is easy to lead to the failure of model printing, if this is the reason, it is necessary to re-slice the model and add enough support;

3.Exposure time is too short also easily lead to printing failure, then the exposure time can be extended appropriately (in s);

The display does not light up

Check whether the power indicator is on when the power is powered on. If the indicator is on normally, disassemble the base according to the following figure.

Check whether the cable connecting the power supply to the mainboard is loose.

If it is not loose, please connect the motherboard and the computer with a USB cable, and check whether the device manager on the computer can recognize the motherboard. If not, the motherboard is broken and needs to be replaced. If it can be identified, it is the display is broken, need to replace the display, please contact technical support to buy.

Cleaning of resin after printing

Please click the button on the screen to clean the tray and clean it with alcohol or professional IPA cleaner. If the cleaning is still incomplete, please click the link below to buy a cleaner. GWC01GWC02

The printer cannot recognize the file

Alkaid can only identify files with the suffix.ctb and print them. Please print the cut files on the USB flash drive.

If the printer cannot print.ctb files, refresh the firmware. Below is the firmware link, please download the firmware file in the red box and refresh it.

If the file is still not recognized after updating the firmware, then the USB port is damaged and needs to be replaced, please contact technical support to replace it.

Support adding technique when slicing

1.Thin supports are easier to remove and cause less damage to the model, but a higher support density is required to ensure the strength of the support.

2.Check again after automatically adding support. Some places where the support density is not enough, you need to manually add some, or some of the bottom of the suspension without support, you can also increase appropriately.

3.When the model is printed without a bottom, pay attention to the amount of support closest to the bottom must be sufficient.

4.For models that need to be pumped and punched, support is added after the shell is pumped and punched.

5.Some models are uneven at the bottom, and can be appropriately raised to print, or offset a little downward (if the bottom is not high), which is equivalent to cutting a small part of the bottom.

6.Hollow models or after the shell, remember to drill holes so that the resin inside can drain out.

The model is split-level

1.Check model support

Check that the model support is adequate. When the model support is not in place and the density is not enough, it is easy to cause the model to shake slightly when printing and demoulding. In this case, it is recommended to increase the support density or manually add the support fixed model.

2.Check box FEP film

Check whether the release film of the material box is relaxed. If there is slack, it is recommended to tighten the release film steel ring.

3.Check Z-axis operation status

If there is abnormal noise in the Z-axis operation, the swing amplitude is too large, or when the Z-axis is running up and down, the manual printing platform is stuck, you need to loosen (do not screw off) the 8 screws that fix the printing platform on the wire rail, and then move the Z-axis up and down, and lock it again after smooth

4.Check print platform

Check that the printing platform is locked. When locking, pay attention to the diagonal lock, and pre-lock first, and then lock all.

5.Check tank

Check the tank for residue. Residue can cause the model to print faults, so check the tank before each print and clean the internal residue in time.

There is residual resin in the model

1.The support is too little to pull the model. Need to re-slice to modify the support.

2.If there is a problem with the model itself, the problem can be solved by modifying the modeling;

3.Wall thickness is also a very important parameter, less than 0.5mm mechanical strength will be relatively poor, want to ensure the effect of the wall thickness can be increased to more than 1 mm;

4.If the material tank or release film is damaged, it will lead to poor light transmission, and the liquid resin can not cure well, in this case, a new release film needs to be replaced.

Precautions for resin

1. The resin is disposable and cannot be reused.

2. Do not touch eyes, skin or clothing, taste or ingest the resin material. Use only under good ventilation.Please pay attention to air circulation and take protective measures. Wash thoroughly after operation.

3. Resin is liquid state, there is a slight smell, please wear a mask when using, so as to avoid inhalation of aerosol, causing infection.

4. The resin should be stored in a sealed container, sealed in time after use, and placed in a dry and well-ventilated place, not exposed to sunlight.

5. In case of accidental inhalation, leave the scene and seek medical attention.

6. In case of contact with skin, wash skin with soap and water or seek medical advice.

7. In case of contact with eyes, immediately open eyelids, rinse with soapy water for about 20 minutes and seek medical attention.

8. If accidentally inhaled or swallowed, do not induce vomiting, keep the state of rest, and promptly sent to the hospital for treatment.

9. Disposal of waste in accordance with local environmental regulations.
