Okay, I converted my Sherline 5000 series mill to CNC and mounted limit switches to all axises. The Y axis switch near the rear column will stop the saddle before it hits but if I have something wider than the mill table it will hit the column and not trip the switch because the saddle has not reached the switch yet. Does anyone have a photo or suggestion on how to make that limit switch more reliable to sense anything approaching the column. I could do it with opto swtiches but I am trying to use micro-lever type instead to keep it simple.
Can anyone help.
Thanks
