Title: mchine is moving in Metric? instead of inches
Post by: Tony G on September 22, 2012, 04:49:58 PM

Hi. While running mach3 today, instead of it moving in inches, it seams to be moving possible in metric????  I will jog in the width of a 1/2" bit and it will say it moved +13.78 or similar number instead of .5. Any thoughts on what I might have messed up without noticing it?

I am using cut3D to generate the tool path, yesterday I installed a new post processor since the one I had was in mach arc inch and I was sent the mach inch one. Not sure if this would be the problem or what.

Thanks

Tony

Type G20 into MDI and hit enter then see if its ok.

I tried the MDI suggestion- IF I did it right I could not tell  a difference-BUT, in the process I recalled a while back I had to delete the tool change line to solve another problem. So, I tried it again, while I have no idea why this would effect this problem, it did seem to take care of it. I did a few short start/stops and the numbers seemed to be right. So your suggestion helped me recall another fix. Thank you very much.
