I have been doing some reasonably precision things on the machine lately as I have been making a 1926 style mechanical TV. I thought I would simply cut some little belt pulleys out of acrylic. I made them, and fit one on a motor and it wobbles like crazy
I did some measurement and found when I cut a "tight" 5mm hole and stick a shaft in it. Then measure the shaft angle I get 3 degrees left and 1 degree back. 3 degrees is huge!
I looked around and cannot see anyway to adjust this other than make a custom mirror holder for the mirror in the focusing head. Has anyone solved this problem on their machine or have a solution? Cutting a perpendicular hole would actually be quite useful to me.
Cheers
