Drivers
The printer cannot communicate with computer?
Check the USB serial chip at first:

Firmware
1.How to upload firmware?
You need to upload the firmware via Arduino IDE 1.0.1.
If you upload the fw via Arduino 1.8.5 then you will get the error:
fops_t or X/Y/Z min pin redefine

2. How to change the motor direction in the firmware?

Motor
1.Motor’s non-action

Extruder
1.Extruder does not work normally.(The temp of it <180C ,it won't work because the temp protect)

3, How to use the spare extruder slot?

4.Hotbed/extruder has a MIN TEMP/MAX TEMP Error

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.

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.
