Weird issue with Mach4

Hi all.
This is a weird issue that pops up from time to time. I am using Rhinocam 2018 for toolpath generation. Sometimes Mach4 reads fairly simple files mixing up coordinates and adding circular sections to toolpath. It’s like Mach4 unwraping toolpath to vertical rotary in a very strange way. Any ideas?

It looks like your arcs (G02 & G03) and the absolute vs. incremental setting for your arc centers are out of sync. Try adding a G91.1 at the top of your file, and if that doesn’t work, use G90.1 instead. There might be a Rhinocam setting to fix this.

Thanks!
G90.1 worked.

The only place I was able to find for arc centers in rhinocam settings is here

There is a setting in Mach4 somewhere to set the arc radius if that is too big the cut goes around the outside of the corners. I had this issue years ago but can’t remember where to set this right now.
