Single limit switch per axis (moving switch)
« on: June 03, 2017, 01:11:06 PM »
Hello. I am retrofitting a CNC router with a new CSMIO controller and will be running mach.  Each axis on the router only has 1 limit switch that serves as both the positive and negative limits.  It does that is by mounting the switch on the carrier and then it uses stops setup at both ends to trigger the singe switch depending on which way the carrier moves.  My question is, am I able to use this setup with mach to do my homing, or will I need 2 separate switches/inputs coming into mach? (one for the positive direction, one for the negative direction). I see that mach has both an x++ and an x-- indicating it is looking for 2 separate inputs. Thanks in advance for you help/input.

No it will work just fine. Mach ignores limits when homing. I use the same input for all three axis also.

Thanks Don. So, does that mean I would pick the same input(sensor) for both the x++ and the x-- in the configuration in mach?  How did you configure yours in mach?  Thanks,
