Yesterday I made my first cuts with my MPCNC. They were 10 t-slot recesses for my work surface. The job failed twice - once because I tripped the circuit breaker on the power strip by plugging in a shop vac, and once because the z axis lost some steps and wasn’t lowering the tool low enough to cut. Each time I went back to ESTLCAM, deleted the cuts that had already completed, and restarted the job. The problem is that I couldn’t get the exact same 0,0 point each time. Using endstops would have allowed me to have a fixed 0,0 point to start from.
I had initially planned for my 0,0 to be in the upper left hand corner, but since my machine is mostly enclosed, it would be hard to mount microswitches where I need them, so I think I’ll be making the lower right my 0,0.
Of course, adjustable endstops would be a more versatile solution!
What do you think? Does my idea make sense? Endstops might not be for everyone, but I bet it’ll save me then I have failed prints in the future.
