# Before switching on the electronics for the first time
|
||
|
|
## Set to 5V output on D3 DC-DC step down
|
||
|
|
### Option 1
|
||
|
|
- You put 12v between IN and GND
|
||
|
|
- With a multimeter you measure VO and GND
|
||
|
|
- Turn the potentiometer until you measure 5V
|
||
|
|
### Option 2
|
||
|
|
- Cut the jumper on ADJ
|
||
|
|
- Put a drop of tin on the 5V jumper
|
||
|
|
|
||
|

# Adjust the reference voltage of the stepper drive
|
||
|
|
You have to adjust it to supply 1A to the motor, this way the motor will hardly heat up and it will have enough power.
|
||
|
|
- Turn off the electronics
|
||
|
|
- Disconnect the motor
|
||
|
|
- Turn on the electronics
|
||
|
|
- Stop from the web interface so that the hotend is not heating up
|
||
|
|
- Measure the voltage between the small potentiometer on the driver and ground
|
||
|
|
- Turn the potentiometer until you measure is about 0.4V (0.4*2.5=1A)
|
||
|
|
- Once adjusted, turn off the electronics
|
||
|
|
- Connect the motor
|
||
|
|
- Turn on the electronics again
|
||
|
|
|
||
|
|
Never connect/disconnect the motor with the electronic on
