General Mach Discussion / Moving to lower Z point directly after start

« on: January 15, 2014, 10:22:55 AM »

Hi,

I purchased Mach 3 yesterday having re-built my CNC machine and upgrading all the controllers, of course my old software was no good as it was tailored to the old hardware..

I have just tried to do some milling and the strangest thing is happening, Mach3 starts from zero but then drops in the Z axis before cutting. This is of course ruining my piece because it's milling right through it..

Does anyone know what is going on? The code is coming straight from Solidcam and I had no problems before, here is the initial G-Code.


Thanks
