 Thanks I reset the de bounce at 1000 and that seemed to fix the problem and also made the z axis work alot smoother, A GREAT IMPROVEMENT!

General Mach Discussion / z axis

i have a plazma machine that has been running good but it started acting wierd . i am using sheet cam with the mach 3 and when the torch touches the metal and sets the home switch on the floating head it is kicking out the run and stopping all the geco motor drives. sometimes it will go ahead and work and cut beautiful but it is a 50 50 chance if it will work or not.  i have used this table for 6 months without any big problems until now. any help would be appreciated!

Scott,

Thanks for your input.  Sorry to bug you, but I'm not really sure how to add a new DRO to my main screen.

Also, I'm not too sure how to make a macro.  Sorry, but I'm really not much of a programmer.

Any chance you could help me out with these issues?

Thanks

General Mach Discussion / Gcode to re-zero Z axis
« on: October 18, 2007, 09:55:04 AM »
I've got Mach3 running pretty well right now.  I just set up a floating torch head, and have a few code questions.  I can get the G28.1 command to reference the home switch, no problems there.  But, after the reference command, the Z axis DRO doesn't reset to zero. 

What I would like to have happen is the G28.1 command be run to reference the home switch, the Z axis offset be reported, and then the new Z height it referenced become zero. 

My thought is that this way every time the torch head references the switch it re-zeros for the code to run based on the height/thickness of the metal at that location.  By re-referencing before every cut I am hoping to avoid the torch dragging on the metal or trying to fire too far above the metal. 

I am currently using LazyCAM for my .dxf to Gcode conversions, and I'm not sure of any way to get it done in LazyCAM.  Any help would be greatly appreciated.
