Hi drwhen,
You are right i am having a little difficulty with the new hardware..but, i think i will resolve the issues very soon... I have already got some good success(60%) and the remaining 40% success is very near
I think my stepper motor gearbox is non-linear... and, now i believe that this is root of the evil... For plane-less scanning, the laser movement must be very uniform..but my stepper gearbox has jerky at some point..i think the double worm screws have some problems with the wheels and the stepper and gear shaft misalignment may also be the reason...
I am currently thinking of buying ready made solution from
Stepper Motors with Planetary Gearboxes
and trying to purchase following product:
11YPG202S-LW4-R189 This planetary gearbox comes with Nema11 bipolar stepper motor with 189 reduction ratio...
