So I've been using Mach 3 on my machine for years, NO PROBLEMS.
This morning I went to cut a carving board and even though in the design and previews the carving was in the center of the board, Mach 3 decided to move everything to the upper right corner.
I'm behind on my orders and hope that someone can help me.
Because I'm curious, I loaded files from previous jobs that ran just fine, no problems, now they have the same issue.
Grrrrrrrr............
Any ideas as to what might have changed in Mach 3 that causes this problem.
I can still set x y and z to zero on the lower left corner so it is starting at the correct places.
Any answers would be appreciated. Thanks in advance.

Double check to see what post processor you saved it in.

Re: Need Mach 3 help
Gary,
Thanks for the quick reply.
All of the files have the same post processor MACH3 ARCS (inch)(*txt)
What should I look at next? Some setting in MACH3 itself.?

Re: Need Mach 3 help
When you first set it up to cut, did you zero X & Y to the center of the board before doing tool height?

Re: Need Mach 3 help
Trying to not waste wood. I did a test cut at a very light depth.
Attached are screen shots of the preview window, the design window and the actual board.
Notice that on the computer the circle above the letters is concentric. But that's not the way it carved.
Also the letters in the preview take up less of the curve than when they actually carved.
I'm stumped. Perhaps someone can point me in the right direction?

Re: Need Mach 3 help
No, In the six years I've been using V carve pro, I've always set x and y at the lower left hand corner. Never centered it on any of the hundreds of jobs that I've run. They have run fine until now.mark-s wrote:When you first set it up to cut, did you zero X & Y to the center of the board before doing tool height?

Recheck your original vcarve file, under your Job Settings, make sure the XY Datum position is bottom left (as you intended) and make sure the Use Offset is unchecked and there are no numbers in there. I had a file I re-opened once that was older... somehow that offset got checked and huge numbers got put in there somehow. It took my spindle for a ride when I started the carve. I am not sure how on earth that got changed.. but I was very new back then. So I just scratched it up as lesson learned. I try to ensure that nothing in that setting somehow appears anymore... lol.
Your mach3 shouldn't be the problem because it is doing nothing but reading your gcode from vcarve. However, it may be possible that your setting in mach3 got corrupted. After I got my chinese 6040 machine, I wrote down the step-by-step procedure to setting up my mach3 for my machine. You might want to check those settings. Maybe even uninstall, and reinstall mach3 and reset the settings for your machine.

Re: Need Mach 3 help
Is the circle the same diameter in the actual cut as designed? The lettering is weird. All I can think is that the unit scaling (or whatever it's called in Mach3) is off.
