General Mach Discussion / Re: X and Y off by .080

« on: November 06, 2013, 12:34:40 AM »

Thought I would post back. This was a blunder of my own... I was using my 1/8" end mill bit as my touch probe and it was off. I put in a solid 1/4" pin to use as a touch pin and all work fine. Sorry guys, chalk it up to being newbie...

Thanks for the help

My work piece is 2.5" x 24". The 2.5" being X and 24" being Y. I'm trying to cut a 1" square in the middle of X. If I set XYZ to zero then manually jog the bit to the center of X on the work piece itself in MACH it is actually -.080" short of the center line. Same thing happens in the Y direction. In the Y direction it does not matter if I jog the bit 4" or 20" MACH is still -.080" short of where it should be. If I hit the button to take me back to XYZ home it goes home just fine and returns to XYZ zero. I hope I'm making sense.

Hi All,

I noticed a problem last night, I don't know that it is a Mach3 problem but thought I would start here. After setting the XYZ zero for a part I loaded my GCode and cut the part, milling some holes and a square in a piece of alum. The placement of the cuts looked off so I checked with a caliper and the X and Y were +.080. I tried reloading the Gcode and resetting the XYZ zero several times and the xy were still off. I was able to reload it one time and the xy were correct so I ran another test and it worked fine. Then I reloaded and reset again to test and the xy was off again.

Today I loaded a different GCode and noticed the same thing, the XY was off by +.080 (approx.)
I'm not sure where to start looking.

I'm using BobCAD V25, Gecko G540, Mach3. I was using an .125 end mill.

Suggestions? I can post the Gcode or anything else needed.

Thanks,

Chuck
