Well, if it's a bug, then the bug works very well.
Yes, I actually agree, but I think (I am very sure) the bug is a programming error rather than a random corruption. (I have about 50 years of programming experience.)

I wrote the code for this from scratch. I may have mentioned it in Gearotic recently. It runs, and makes GT2 pulleys.

True.
Fwiiw, going from XL belts to GT2 belts seems to have improved the zero-holding from 0.15 mm to 0.5 mm, so I think it was worth while.

my 3D printer use's GT2 pulleys and belts and it's quite good at 5000 mm/min

Aaarrgghh ! ! !
That should be be:
'improved the zero-holding from 0.015 mm to 0.005 mm, ' (15 microns to 5 microns)
What was I thinking????

that's better that's where I would like my big router to be at all the time but it's big so 0.01 to 0.00 over 1000 movements on a single axis is good, I just have to keep it at 1250 mm/min any faster it's moving out by mm at a time in any direction. but it's a easy fix $1200 worth of new parts it came from bad advise years ago lesson learnt only listen to experienced users that have a good name on here not the others.
