10mm we started with plus 5mm the offset moved away from it's zero Offset coordinate. Now you'll endup with 15mm positive in the Dro which is the true WORK coordinate. Now type G92 z0 and you'll see the Z dro change to 0 now type G0 z5 which will simulate movement 5mm positive. Next Zero the Work coordinates by zeroing the DRO's then jog a set distance away say 10mm positive. First make sure any Offsets are cancelled by typing G92.1 If you cancel the Offset by using G92.1 you'll see the True WORK coordinate. It just applies an offset Coordinate from this WORK coordinate. It doesn't actually Zero the DRO or should say Set the Zero WORK coordinate. (g92 z0) then Moves 25 away(g0 z25) resets the offset coordinate to Zero at this point (g92 z0) then moves to 1mm above this (g0 z1). What it's doing is using the probe to find the material surface and where ever that coordinate falls in the current WORK Coordinate system (G54) then it sets an offset coordinate value. 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.
#SHEETCAM Z PROBLEM 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. Mach 3 is great stuff just very heady.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.

I am very serious let me know and sometime we can get together and go this stuff with either your machine or mine acting as the scapegoat to make sure we are getting it right. BobCAD-CAM is very easy to understand and fun in comparison.

StevePass the bottle of Scotch as I own a copy and the videos leave my brain in a puddle. I`m still playing with a unfinished machine I have not made the table "Y" axis or "X" depending on your view, in fact I`m still 2 motors short, my last 2 Gecko 203v`s only got here on Sat, I have not even had time to connect them in yet I have not loaded any G Code into Mach3 as of yet.
#SHEETCAM Z PROBLEM HOW TO#
Im not even sure how to control speed when cutting yet, Im hoping when I buy Sheetcam it will become evedent, I did get a trial licence but wasted it by not even looking at Sheetcam, trying to learn one program (Mach3) at a time was enough and by the time I got to look at it the licence had expired, by then Mach3 had me gibbering in a corner with a bottle of Scotch Thanks for the help, "preaching to the converted" certainly not, any help or advise is always welcome, your time and advise is appreciated.
