Hmm, ok here we go
That file is not my general standard, it's downloaded from the 'net and yes it's pretty ugly when loaded in CAD, thousands of little lines. However, with normal CV on, it cuts perfectly fine - no issues at all, its only when stop-cv is on that the blips show up and there is one every point where it goes form straight to a curve - no slowdown so should not blip.
It's a minor point and i was just playing about looking for improvements.
Yes, I have not fine-tuned the THC yet, it could well be diving unseen, I will have a play with the dive% settings.
So far I only have the 45A consumables for my PM45, I will be getting some 30A ones to try though. The air is passed through a refrigerated dryer so should be pretty good.
Any chance of a pic or two of some examples of your cuts for comparison, some settings maybe
