Threading in Mach3 lathe
« on: February 19, 2006, 06:17:47 AM »
Hi all

Does anyone know of changes that has been made in mach3 in the past 2 months..... Everything used to work well for me. I have not done some threading for some time.........Now it seems to go haywire.
Current version that I use is latest release.

Except for tool change move the graphic preview looks right but the actual cutting is not correct. All other turning seems to be fine.
When I use Brian's Wizard this is what hapens....

Hi

Did a few tests and found my machine coordinates was set wrong ,that explains the tool change position fault.

I then re-instaled ver 1.84(lockdown) and everything works fine.......  Again after re-instaling the latest version I get problems, everything works correctly up to the second pass witch reverts into a short backward like pass at the end of the thread.

This realy looks like a software problem.

Any ideas on this

Thanks
