Hi @JaredMckie: I want to be clear that the problem is corrected with the system I’m currently using.
I did not isolate the root cause, but when I have time I plan to switch back to the Ubuntu mini-computer to see if the problem comes back.
I have completely stopped using Easel to control my machine. I use Universal GCode Sender (64bit) now, and haven’t seen the unexpected tool paths since switching.
Eliminating the browser from the equation is a quality of life improvement. It is much more like operating a HAAS or Fanuc machine controller and operator interface.
I outlined the setup in this post, so I won’t repeat here. If you have issues transitioning, put up a post about it. This forum is overdue for a dedicated troubleshooting guide.
