Help setting up Commarker D80 chuck in an Omtech AF2028 Ruida controller

[SaggyG (Chris Gaw)]

While I was typing this, I figured out how to overcome my main issue of rotating 2.5 times when it should have been one.
Now, while it is rotating, it is very sticky/jerky.
Pulse rev on controller=2000, rotary setup=2000
Current 3.5 Amps

I have tried adjusting Y axis max speed and acceleration way up and down, but no difference.

I saw a video that I can no longer find showing someone changing the pulse rev dip switches to something else make it work better. I also read somewhere that adjusting the amps will affect the jumping, but I can’t find it either… Dohh.
The motor is warm but feels the same as the X.

Any help or direction is appreciated!

This thread is a quick way to setup a rotary.

A rotary attachment question. Warning: Newb

Configuring for a rotary should not be an issue. I’m assuming you are using the Y axes… you didn’t say… find steps/rotation a. identify the switch settings b. translate from the motor driver placard steps/rotation is then computed based on a ratio. a. value entered is steps/rotation multiplied by the ratio which results in the steps/rotation of the wheel, which is what Lightburn needs to know. This is the basic procedure. [motor-driver-switches] Look up the settings on the devices pla…

If you have issues, let us know… Might want to include if it’s a chuck or wheeled rotary.

Thank you, sir. Yes I am using Y. There is no nameplate or any marking on the motor. It is a ComMarker ComMarker D80 Rotary
I have looked everywhere for the specs and have come up empty.

When hooked to my Com Marker B4 fiber, it works great. The steps per rotation are 12,800. I’m not sure if that will help with the diagnosis.
I thought I had it working pretty well, but I was just using 5x5mm test squares. When I increased that to 15mm square, the left and right sides (Y axis) became wavy. The square is just a square from lightburn, so it should be perfect. You can also see it is really bad on the fonts. I’m about out of ideas at this point…ugh.

@SaggyG

steps per rotation are 12,800

This is defined by the motor driver stepper. On my fiber, it’s 12800, on my co2 it’s 2,000.

Did you follow the steps to make it work? What didn’t work, you didn’t say, either way.

[SaggyG (Chris Gaw)]

I honestly don’t know. I started back at default, speeds back to stock, 2000 SPR and it worked, on the correct size anyway. I think the wavy has been there the whole time, I was focused on the rotation jumps and didn’t really see that. I tried turning off scanning offset as I do use one normally, and no help. I’m at a loss as to why the sides are that way now. If I do a line, the square is perfect, something in the fill…but what?

Thanks for the help. I am usually good at figuring these things out and have been at this a while, but this one, totally stumped, my brain hurts.

If I’m reading your mug correctly, the wiggle is in the X axes.

I’d look for anything not secure on the axes, belt tension… anything that would allow it to wiggle.
