Good to hear :)
I think you may have your backlash speed too high, I dont use backlash myself but its at 100% in your xml and maybe that is just too much. If you dont really need it however best with it disabled and to be honest on a wood cutting machine it would have to have a fair amount of play before backlash would become an issue.

I have ballscrews with anti backlash nuts on all axis'. Why I thought I needed backlash compensation is beyond me.

I never used it before, but like I said I thought maybe it was my solution to circles coming out slightly square so that's why I enabled it prior to me encountering my lost steps.

Maybe the circle thing is a CV issue. I have no troubles with any complex designs or square pockets but that is a topic for another day.

Thanks again!

Maybe just flex with the small diameter cutter? Tried taking small depth of cuts to see if its better?

I think my depth of cut is like .015 using 20% step over? Its not a big deal, I only use that particular tool path to locate a hole that I finish drill on the drill press.
