Strange behavior - cuts really slow then fast

I have blue/great machine with a Ruida controller and it’s behaving strangely when cutting lines. I understand it will slow down when cutting corners. However it is being really weird when cutting a circle. For the inner circle it zips right around and then it cuts the outer circle where it goes very slowly for part of it and then zips around. See the photo. Anyone have any thoughts why it’s doing this?

Thanks,

I didn’t see anything in the setup, although I find it difficult to believe you can use 1% power. Mine won’t lase below about 9.5…?

It would help at this point to give us (me at least) and idea of what you are trying to do. I’m assuming it occurs on the ‘line’ one as you stated.

Is this a new thing it’s doing or? I assume it’s a rotary by the posted photo looks round…

You are correct 1% power doesn’t actually fire the laser and we want it that way. We use the 1% power box there to take the slack/lash out of the rotary. Otherwise we notice that were the laser starts can be a little narrow when it cuts.

Yes, we are on a rotary. Its new to us because this first time we have tried to use line on the rotary. Normally we are in fill mode cutting whatever the design is. For this one, I am trying just to cut the masking tape on glass to use it for a stencil for sandblasting - we don’t want to actually cut the glass hence the low power setting (and using line not fill).

Again the issue is the top of the circle for some reason it goes really slow for that one segment and then goes full speed…

I thought there was adjustments for backlash to eliminate having to do that…

Used to have a sandblaster and used it for similar operations. I bet it looks nice…

Things I know are issues are acceleration setting of that axis. Although I can’t see how that would be an issue related to this.

Can you clarify?
