I built a DIY/CNC using a Novusun NVEM motion controller, NC switches X/Y connected in series and Mach3(demo). The machine jogs well on all axes and the switches work well as limits. However I have some issues that I can't seem to get by:
1) I have Auto Limits Bypass enabled but when I trigger any of the limit switches I can't reset Mach3 in order to back-off.
2) I can't zero machine coordinates unless I power off controller/motors, position the axes manually and start Mach3 without device connections to zero coordinates. I have tried the zero/send to DRO options, no difference.
3) I wanted to be able to use the X/Y switches as both limits and homing, but when I ref-all-home, the X axis moves towards the correct switch but when it triggers, it resets Mach3 and I'm back on issue #1.
Any help would be appreciated.
