Parameter in control-
So I hit the e-stop and reset these parameters for X and Y. With these parameters the part cuts great at 100ipm. The corners are not perfect on the roughing passes but the .010 stock I leave before the finish is plenty to clean it up, and it is WAY better.
Also, I ran the program at feedrates just above and just below the cutoff of 66.4ipm (with the old parameters) and you can see the difference with it just cutting air, it decelerates slightly as it gets to the corners and sounds smooth with the feed below, and if you go above it does not do this and and there is more vibration and "drumming" of the sheet metal.
I thought this might be related to setting 44 "min F in radius CC" after talking to a haas engineer but is acts the same regardless of whether or not cutter comp is on. The Haas guy said that this slows the feed in every g02-g03 move with cutter comp on but reading the manual it seems only to slow it down on certain approaches, not sure what it does. The program runs the same with cutter comp on or off.
Basically I am happy with how it is running now, I can program 100ipm without worrying about gouging things. But it would be great to know more about how these parameters and settings work, anybody have details?
