Hi All,
I have the latest version of Mach3 running on a Windows XP Pro PC.
I am using a Gecko G540 stepper controller, using the parallel port for my mini-mill.
I have some G-Code that I generated with VCarve Desktop for drilling holes - it looks fine to me but when I run it the Z axis doesn't drill down far enough - all the X and Y axes run fine.
As far as I can see the Z axis is -2.5mm short of where it should be for every hole (it doesn't stay there long enough to be sure of the DRO reading). However, the strange part is that if I run the code in Single Block mode the Z axis depth is always correct for each hole.
I have Windows XP Pro and same Mach3 running on my Mac under Parallels as a test bed and it does the same thing - even though there is no hardware connected, so it isn't the hardware, the only thing common is Mach3 and the G-Code.
I have attached one of my G-Code programs (they all have the same problem). Can anyone explain what's going on and give me a fix?
Many thanks,
Davo.
