Ok well G92 is an Offset Coordinate from the exisiting coordinate point. This is from sheetcam, will that not work in mach3? The post processor I have been looking at uses g31 z -100 to drop the torch until the probe switch changes state, g92 z0.0 to zero, then g00 z25.00 to raise it by the preset distance, g92 z0.0 to zero the z axis and g00 z1.00 to preset the pierce height. If you want it to do this you have to alter the Homing script. It will also ignore the Probe input while homing but that shouldn't be a problem.Īlso by default Mach homes each Axis individual one at a time when you press "Ref All Home" they won't all go at same time. Regards "home all" then Mach treats homing separate and just watches the assigned pin, by that I mean it will not watch limits etc unless specificly told to do so.
#How do i delete points in sheetcam code
Ok that's easy enough but if you want DRO's Zeroing etc then it will need to go into a Macro file because you'll need some VB code to do it and Mach doesn't support VB directly in the G-code file.
I also want to retain the top limit switch for the "home all" feature in mach.
I have had a look inside the post code for the mach plasma with THC option in sheetcam and it has the code for G31 seeking so it just needs some options altering and the floating head switch wired to the probe input I think.īasically all I want is to have the torch seek the metal at the start of each cut then raise to pierce height and start.
