Software way be a solution, but currently beyond my level of experience. I will have to look into that. Here is a video example of the speeds that I can scan in with steppers. I have had the motors double the speed in the video but the laser doesn't mark due to lack of power at those speeds. Dialing...

Yeah, I have one and do see "some" correction but it does not take it all out.

How do these other printers like the Form1 not have any lens correction?

Any reason(s) as to not driving the scanner via a stepper? Speeds are slower than a galvo but still fast enought to etch using a CO2.

I am building a mirror driven "glavo type" printer using two high res steppers and digital drivers. My early testing has been productive however I seem to have hit a wall with a pincushion distortion error on my X axis (last mirror before surface bed). Because it is still early I have not ...
