I am using a Biesse Rover 24 that has a tendency to wiggle when it changes direction.
Whenever we program a cutout using an onion skin (finish pass) for whatever reason the tool slows down when it hits corners and eliminates its wobble. It does this on both passes. HOWEVER!! Every time we try and tell the machine to cut through the material (3/4 plywood) in 1 pass it hits the corners full tilt and creates unacceptable wobble marks on the back end of all the corners. Is there a setting that I am missing or a toggle to click to make it slow down around corners? We cant really afford to onion skin every single part. Has anyone else encountered this issue? |

I don't think this is a software problem. I would check to see if your motors and properly seated and tight.

Yes it is primarily a machine issue. What I am trying to figure out is how to replicate a condition that the software creates that mitigates my machine's shortcoming.

You could put a bridge that wraps around the corner.
Usually the machine will slow down a little when it has to raise up in Z and that may create the effect you are looking for. |

Have you tried comparing results with "Sharp corners" turned on & off in your router offsets?

Often machines have lower acceleration rates in thier Z axis than the others. If you have a movement in the Z then the other axis have to match their acceleration rates to that of the slower Z. You could probably eliminate your problem by lowering your acceleration rate in the problem axis. (I would also look into correcting what ever backlash and or servo tuning problems are the root source of the problem, could also be worn drive belts)
