I am set on servos because lasercutting usually works better with them. Mainy due to available faster speeds. Having too powerful a tube and trying to cut paper you run into problem with overdelivery of power at too low max speed.

Laser tubes of 100W+ fire at about 10% of rated power, which is way too much for some materials. This can be fixed by spreading that power thinner by using servos and running faster.

At the moment i'm still struggling diagnosing my stepper motors as is, but time will come when i will go full servo.
