View Full Version : oxy propane cnc preheat problem

12-05-2013, 09:35 AM
I have just built a cnc table running it with sheet cam and mach3 the plasma worked great so I purchased a oxy propane machine torch . it works fine all but the preheat. I have set the preheat for 10 seconds but the torch does not weight 10 seconds it goes straight down to pierce does anyone have any ideas what the problem could be

Many thanks

Stick a P04 10.0 into the code before the Z move

he i have finally sorted the problem. mach 3 was reading the pause code as ms instead of seconds. but when the torch goes to preheat it is moving up to the peirce height and not the cut height. is there any way to fix this in sheetcam? i am after cut and pre-heat at 3mm and pierce at 25mm
