I am using a couple for testing but this seems to be the one I would recommend so far.

I am not sure. That is why the speed thing through me off. I made a smaller file/less commands per mm and it still glitched. When I got it to go glitch free I started turning things back on. one of which says 32bit only and I turned it all the way up…no noticeable performance hit, did not add glitches back. That was continuous ramping I tried every ten “steps” and every other.
This is using inline commands so instead M3 S155 on a line it is just added to a move G1 X10 S155. M106 and the regular M3 did not work nearly as well.
I think we will know more when I start testing the rambo again. It previously got super glitchy in a fairly plain part of the picture. What I assume if few commands. I can see it happen to the machine before I can see the laser results. It is like what was happening with the arcs if that makes sense. It just starts to slow down for no reason.
Yes/no, I keep calling it ramping but Marlin has a few options for it. I use inline commands but find the ramping to have no noticeable effects if you use overscan.
