Warnings

Reversing +/- or otherwise incorrectly connecting power can destroy your electronics and cause fire hazard.

Incorrectly inserting stepper drivers will destroy your electronics and cause a fire risk. Always make sure power and USB is disconnected when removing or adjusting stepper drivers. Always make sure to insert drivers in correct orientation and in the socket correctly.

The endstop pins are Signal - GND - VCC, instead of the VCC - Sig - GND like the rest of RepRaps boards. Make sure to wire them correctly. This is done to allow squeezing fatter traces on the printable board.

DON'T secure Arduino/RAMPS with conductive screws through both mounting holes. The screw may cut into the positive trace creating a HIGH current short.

Pololu Jumpers Steps Configuration

  • Jumpers need to be installed under each stepper driver:
Jumper 1 Jumper 2 Jumper 3 Step Size
No No No Full Step
Yes No No Half Step
No Yes No 1/4 Step
Yes Yes No 1/8 Step
Yes Yes Yes 1/16 Step

For now the default is 1/16 micro stepping (all jumpers installed under drivers)
