I am currently building a laser-cutter (40w, 1200*600) almost from scratch. Everything is documented here -> the blog
The hardware is pretty done, and I am beginning to test the SmoothieBoard (with the official guide).
I have the 3XC Smoothieboard 1.0.x [OLD VERSION]. And I have only X and Y axis on the machine (one motor for X, two for Y).
The problem is that Y min limit switch is not working. It means that when I use Pronterface to home in Y, the motors are spinning properly, then either the aluminium profile or my finger press the limit switch and it does not stop the motors.
The X axis it working fine (homing OK, switch OK) and I wired the Y min limit switch the same way. I also tested it with a multi-meter. I also used the M119 command to test the switches. I think it’s a wiring/board problem…
Enclosed there is the pic of the wiring, the config file and the M119 result (I am a new user, I cannot put all of that)
Thanks a lot guys !!
