I have the following setup:

• Arduino Uno

• CNC shield

• DRV8825

• 2 buttons (2 pins each)

• 2 limit switches

Everything works with GRBL and UGS.

I now need a sketch that allows me to do the following:

Button 1 (X+ & GND on the CNC Shield) = 300 mm up
Button 2 (X- & GND on the CNC shield) = 300 mm down
Limit switches for X+ & X-

My attempts to write a sketch myself were all unsuccessful. Iam a noob.

Can someone help me or give me a tip?
