I recently updated to the latest version of Mach 3 i run a mill and lathe with Mach what i think would great is to have along with the update what it fixes like corrects bug in arc move ETC .
Recently  when i updated to the latest version of Mach on the lathe the G-code was all out of whack and these were files i had already cut so i know there were no problems before the update i had to remove the update and all it's files and then go backwards from 2.63 up to get my files working again letting us know what the update dose may save some time and work would be great if possible.

As far as I am aware there has not been any Turn specific work been done in Mach so I am unsure why you would have problems.
What were the problems you had?

Hi Hood
Thanks for your reply, after the update the arc's turned into circles and and figure 8's going backwards to earlier version's thankfully i saved them i was able to get the files back on line.

Sounds like your setting for Reversed Arcs In Front Toolpost somehow got changed.

If that's so then why when going back to an earlier version of mach would it correct itself? oh and i am not using LT the roughing is so so the finish starts backward rear to front.

Dennis

Is this what you're looking for?
