Plasma Z retract not occuring before XY rapids
Posted: Wed Jun 23, 2021 6:41 am
SheetCam 7.0.12, Mach4 Plasma Post
Mach4 4.2.0.4612
ESS build 275
When using the above set up and Mach comes to make a rapid between cuts, the Z is not retracting to it's safe height *prior* to the X/Y travel. instead it is progressively reaching it's Z height in the same way that the X and Y axis do over the full extent of the move. This is causing problems.
When I run a simulation in Sheetcam, the Z moves to it's correct safe height before the X and Y moves start (as expected), but not when I actually run it in Mach4
When I run the machine as a router with the same setup, but using a Mill/ Router post this doesn't happen and the spindle retracts prior to rapids as expected.
this is a little chunk of the code Sheetcam is writing (from one cut to the next)

N0140 Z0.0000 M03

At line 130, SheetCam simulates this as the Z move completing before the X/Y moves start, but, as noted above, this doesn't happen.
I have limited experience, but I believe SheetCam should be writing something like:
N0100 Z0.0000 M03
N0110 G02 X98.2146 Y1181.7854 I1.7854 J-1.7854 F5000.0

*N0125 G00 Z20.0000*
N0130 G00 X1301.7854
N0140 Z0.0000 M03
Any ides as to how I can get this to happen?
TIA,
Nicholas
