I have an answer
Yes, the nozzle height is the #1 thing to set correctly but if you are
willing to print a "raft" under the part rather than just a "brim" around
the part. The height is no critical.It does waste plastic and time
and requires finish work with #600 wet and dry paper at the place where the

If there is an error, my bet is the parametric pulley designed program has
a bug and/or the author made some simplifying assumptions and the tooth
profile is not perfect. You would have to verify the program is correct.
Do this by comparing a generated pulley to a same-size pulley design that

Greeting all;
Messing around with the parametric pulley designer, I have made a larger
86 tooth pulley for the big pulley on the A axis supplied with the 6040
mill. I'll also change the belt pitch as its presently a huge XL.
But the chosen belt, a GT2_3mm, is not a good fit, throwing a just
