Caveat: I don’t own an AtomStack, but have built & tuned several CNC machines.
Based on what I’ve read around here, open-frame diode lasers arrive with speed and acceleration parameters pushed to the absolute maximum values that might have once worked on a pristine machine carefully assembled by folks heavily invested in meeting whatever bullet items appear in the marketing materials.
The values programmed into the controller you just bought do not necessarily produce precise results, as the mechanical structure flexes and jitters under the forces slinging that heavy laser head around.
So the simple answer is: you’re gonna have to stabilize the hardware, tweak the values, measure the performance, and make your own quality tradeoffs based on whatever matter to you, as seen on your workbench.
For example:
But you can have plenty of fun while gaining plenty of knowledge in the chase!
