Hello everyone,

I’m looking for a rotary axis that I can purchase to mark Yeti Tumblers. The builds that I have found are incomplete, inaccurate parts list/sources, or just won’t work for my application. I really don’t have much time to build one. Can anyone help with locating one to purchase, or know of someone looking to sell?

I was looking at that one, but saw a review say that they couldn’t use anything larger than 2" in diameter on it, due to its height. Do you know anything about that?

You will have that problem with any rotary, the solution is to cut the bottom open in the work area, and raise up the case on supports to give more Z axis height. I used metal framing studs to make a square platform for the laser to sit on it raised it up 3.5" in height, and I use an aluminum oven drip pan underneath to prevent stray laser strikes from hitting the table it sits on. Hope this helps.

@funinthefalls oh, so regardless of what rotary I used, none of them have a low enough axis for 3-4" diameter piece? I could swear I’ve seen people using them without the bottom cut out.

You are probably remembering seeing someone with a 50 or 60W machine doing it, they have deeper work areas than the K40

Yeah with a 50.8mm lens focal length you are looking at a max depth of around 91mm (3.5") for most K40s I believe.

10

Ah very true. I wonder if the LO rotary would work with a 38mm focal length for my needs though.

11

Not sure. That will only gain you about 0.5" though.

12

I guess I’ll have to try it and report back! Lol.

Thanks for your helps, guys

Just looked at the LO rotary again and it requires a different driver for the motor. I don’t understand why they wouldn’t use a Nema 17 motor to be a direct replacement.
