I run Mach3 in my new 3 axis 4 motors table router cnc and for the first time I use ESS interface instead of the parallel port, my experience before has always been with the printer port. I run a NC code (has a lot of curved patterns and straight lines for testing the new machine) which I used back in 2018 and was working very good then but now it cuts straight lines perfect but when it hits curves the cuter moves in steps of about 1/8”, kind of jerky I would say. This code in the past used to cut the curves fast like straight lines.

I tried different NC codes I have from the past and all are the same.

I wonder if anyone knows what the problem is, perhaps since I’m new to ESS I missing some setting(S)

Thanks

Could incremental or exact stop be behaving differently!?.

Thanks for the Help

General Cinfig / Motion Mode was set to "Exact Stop". Changing this to "Constant Velocity" fixed my problem
