Print problems
1.If you find the nozzle no filament out
1)Check your PTFE tube plug is deep enough/Smooth

2)Refer to this video clean your hotend

3)Check the extruder motor direction is correct
If the direction of it is not correct, refer to the part of"Motor"
4)Check the spring of the feeder have enough strength/Too strength of the spring will make the filament broken 5)Clean then gear of the feeder

2.Y axis layer shift
1)Tighten the Y-axis belt
2)Check the vref of the Y-axis motor driver board
For A4988:0.8~1.0V is ok.
If you think A4988 is too noisy, you can replace it to TMC2208
For TMC2208:0.7~0.8V is ok.
If it allows, you'd better add the heat sink for TMC2208(It will overheat if you don't add it)
Refer to this post adjust the vref of the motor driver

3.The extruder is very noisy A10M
1)You can add the oil to this area 2)You can loose a little for the screws 4.Add the purge bucket for your A10M/A20M

Mixer software
The mixer software is for the dual-multi mixer hotend printer.
You can edit it to a single color/Gradient.

Extruder
1.Extruder
Extruder does not work normally.

2.Nozzle type and hotend
The nozzle type of A10 is m6 thread;
Hotend of A10: The nozzle type of A10M is m7 thread;
(It is not the standard MK10 4mm inner diameter nozzle.You need to check it at first.The default inner diameter should be 2mm)

3.Hotend clean and nozzle replce

Hotbed
1.Note:
If the hotbed won't heat,you can remove the clamps from the four corners of the hotbed

PID tuning
Tuning refers to the parameters adjustment of a proportional-integral-derivative control algorithm used in most repraps for hot ends and heated beds.
eg:M303 E0 S200 C5

PID needs to have a P, I and D value defined to control the nozzle temperature. If the temperature ramps up quickly and slows as it approaches the target temperature, or if it swings by a few degrees either side of the target temperature, then the values are incorrect.

Where to find the firmware and how to install it?
1.You need to upload the firmware via Arduino IDE 1.8.5(Use the 1.8.7 or higher version may cause the motor work abnormal)
