So, I have an extra stepper motor, lead screw/bearings/coupler, and an extra Z axis slot on my motherboard. I also have my camera (C920) mounted statically in the corner of my lack enclosure.

I’m planning on putting the extra stepper and lead screw in the corner and having the camera go up with the Z axis, but at a slight distance…

This all seems fine, the only issue I can forsee is having the current to drive the 3rd stepper - my board is a BTT skr mini v3, so I’ll be running 3 Z steppers off of a single driver. Are there any inherent issues with this, or any others I’m not thinking of?

Thanks!

    The stepper drivers run directly of the main power supply through Vcc, so assuming you haven’t added any extra heaters or other crazy amounts of power draw, you should be just fine adding another motor.

    Using the second z for stability would be a more traditional use of those parts but your idea sounds like a lot of fun!

      So I already have a dual Z setup, but since it’s a single driver for Z I just run a split cable to those two steppers, so have an open JST on that same driver. I figured that the draw wouldn’t be an issue (and even my LED’s are running off an independent 5v60a power supply that runs the wled setup, so nothing other than stock and the already extra z motor drawing power. Sounds like it might just work, hell let’s give it a shot just need to print some parts will update with result
