Z axis end switches

Machine: replace this text with what machine you have and what controller it came with

Board: replace this text with what board you have (LaserBoard, Mini, or Remix)

Firmware: Smoothie or GRBL-LPC? “I have a new board and I’m using whatever it came with” is also a great answer!

Problem/ Question: Please provide a detailed description and pictures of your machine/ board/ wiring.

Did you provide those pictures? We need pictures to understand your setup!

I’m adding NC mechanical end stop switches to my powered Z axis on my K40 and I have a couple of clarification questions. I’m using smoothie

I plan to make the following changes to the cohesion, 3-D laser board firmware.

  1. Uncomment #gamma_min_ endstop
  2. Set “gamma_max_travel”
  3. Set “gamma_homing_retract_mm”

should I be making a change relative to the; gamma_max_endstop ?

Any other changes?

When I home XYZ, does Z home to max or min? If it homes to Max, is that based on the end stop setting or number 2 above, “gamma max travel”?

Thank you,
Chuck ,
