Thanks for the reply!

Yes, I was light on the focus and measuring beam alignment as it's rather involved as you'll see. I'll try to add it in the future versions. The out-of-focus value was by...

Thanks I'll try those pins.

Index would tie a CAD drawing position to a repeatable rotation position. But not absolutely necessary.

Thanks for the reply. I thought of that but looking at the connector, back to the drive electronics won't tell me much. I would need to look from the drive to a connected motor in the rotary (which I...

I just bought a generic DIY rotary attachment for use with my Universal Laser X2-600 CO2 cutter/engraver. The attachment comes with a connector with 4 pins (required for a 2-phase stepper motor) but...

Hi,

I've been using a CO2 laser engraver/cutter since 2002 and have created a tips and techniques document on what I've learned (and wish I knew before). I'd like to share it. It's really a...
