Back in time for gift season sounds like a good goal.
What’s left is to check the microstepping, I’m not sure what it should be but its probably wrong, securely mounting the stepper driver and putting strain relief on the cable. I didn’t see the Lemo connectors, but if they’re in then those should probably be put on too.
It wasn’t working on one of the lasers, my guess is the connector at the laser side is broken.
