Rotary won't run a LB material test

Aeon Mira 7S with RF tube. Using roller end of a LensDigital Omni 2.0. Rotary works fine - I have been able to engrave tumblers but when I go to run a material test, the rotary does not spin and the framing is a rectangle (as if it was a flat material). I know one other person that has had this issue (not resolved). LB v.1.7.07. Settings attached. Any recommendations are welcomed.

Does the Mira use the A axis or Y axis for the rotary? What you’re describing sounds like it uses the A axis, but the material test uses the Y axis. I don’t think you can designate using the A axis in the Lightburn material test. You will probably need to create a manual material test to have it work with the rotary.

The other issue is with a roller and the way a material test runs, the probability of the tumbler slipping when it goes back and forth is great. In other words, the Lightburn material test engraves one square then rolls backwards to engrave the next one on a line.

Here is a video I made showing how to make your own test grid.

Thanks Tim. The Aeon Mira uses the Y axis and I have seen people run the standard material test on a tumbler with an Aeon. I know one other person who has this issue and it has not been resolved. There is a well known maker who runs a laser course and she has not been able to figure out the issue (she can run it on an Aeon with no problem). I will watch your video and take the time to make my own grid. Your YouTube videos are helpful. Thanks for the response.

OK, I don’t quite understand. You say the rotary doesn’t spin, but yet it frames a rectangle. How is this possible? Is it that the rotary does spin, but not as much as it should?

The rotary works. I’ve done a tumbler on it. No issues. When trying to run a LB material test, the laser head moves and makes a rectangle in a flat plane which is the size of the material test, but the rotary does not spin. If I hit start, nothing happens even though the preview shows what should happen.

So you’re saying the head is moving on the Y axis? I’m not familiar with Aeon’s rotary setup. Do you unplug the Y axis and plug the rotary into that connection or does it have a dedicated rotary connection?

Dedicated rotary connection. Nothing gets unplugged. I have a short video but the upload only allows pictures.

Ok this is above my knowledge level. If nothing gets unplugged, I thought that would be using the an axis. Something has to differentiate between the 2outputs.

Thanks for thinking about it. It doesn’t happen for everyone with an Aeon laser, but I know one other person with this issue. I will be making my own test file as I have wasted too much time trying to figure out the issue.
