Yesterday I went to set up my workbee for a cut. I tried to home the machine. The z axis homed normally, but when the x and y homed it seemed that the x didn't move independently. It moves just a hair towards the limit switch then backs off when the y axis hits the switch. It seems like it thinks it hit the limit switch. The switch works. The switch seems to be fine. Any ideas?
Most likely EMI causing a false trigger early in the homing cycle: couple options -space limit wiring far from mains/motor/router wiring - upgrade to Xtension Limit Switches (built in EMI filtering - upgrade to a BlackBox (built in EMI filtering) - wire in a 0.1uf Cap and 10k pullup for each limit (no need with Xtension Limit Switches or BlackBox) - add ferrite filters to limit switch wiring
