Dual endstops issue

Software / Firmware
1

Hi there! I have recently build a MPCNC and It works fine.
I have a doubt: if I’m using the X port on my Rambo board to power two steppers (wired in paralell) and the same for the Y, Can I use the dual endstops function? Connecting the endstops to Xmin and Xmax as the tutorial says?
Or should I use the E0 and E1 ports to power the steppers (in that case I dont know how to set those ports as X2 and Y2).

Thanks.

  1. Don’t use parallel wiring. The current gets split and the torque is proportional to the current, so you will skip steps.
  2. No, with two motors connected to the same driver, you can’t get auto squaring. Marlin can’t adjust them independently, so it won’t be able to adjust them to touch each endstop.
  3. Grab new firmware from MarlinBuilder releases. The one with V1CNC_Rambo_Dual should be right for you.
