Using partworks to convert Sketchup vectors for ply cab cutouts.
All goes well when machining, but unable to figure out this behavior:
When doing final cutouts, cut speed drops to what appears to be about 1/8 - 1/4" per second (excruciatingly SLOOOOW....). This will happen on a rectangular side up to 30" length, so I don't think it's a speed ramping issue. Upon completion of that leg and continuing to next side of rectangle, it shifts back to normal speed.
Qualifiers:
Dados, rabbets and hole drilling processes are perfectly accurate and smoothly executed by machine prior to final cutouts.
Appears to be happening on initial leg of cut only, and even goes full speed upon second pass over same "slow" side of cutout.
Using two climb cuts, one final conventional cut, and will do the same on first side of final conventional through cut, but not same side it slowed on for initial passes. I have copied rectangle to additional layer to generate final clean-up conventional through cut, as I thought it was necessary to enable batch processing of toolpaths.
Thought it may be duplicate vectors, but just cut a single sheet and still had partworks open, so I immediately double checked - no open or duplicate vectors in drawing.
In anticipation of this issue, I completely erased imported rectangle cutout vector and re-drew in partworks to be assured it was not a Sketchup remnant, but experienced same result.
I'm stumped
