I understand what your saying I am a machinist by trade
and Ive worked on some cheap cnc's and it is possible in some
instances to program around backlash
I would try to make sure I was off the part and move in the direction
to kind of get the backlash out before final cutting
This was on a cnc lathe with about 10 to 15 thou of backlash thats
alot

I'm wondering about backlash and the steppers missing or skipping
do you think there is any correlation
I'm still considering Bill Wainwrights servo system I think its about
1800.00us dollars
I sure didnt know there was this much to this whole thing.
What I would really like, is to see a retro mill/drill run with my own
2 eyes. maybe I am making more out of this than I need to.
