Using mach 3 and SheetCAM and AutoCAD.
I have drawn up a square, 75mm x 75mm with a round corner in the top
left hand side. When I cut it out, it feeds nice and smooth along
the straight. Then where the straight stops and the arc begins to
turn right, the machine will pause for about a quarter of a second
or so.
It will not maintain that smooth feed into and out of a corner.
Goes along straigh, sort of has a quick small shudder or jerk then
moves around the corner, then jerks again as it comes off the bend.
Then it goes good along the straight again.
I have notice in SheetCAM that there is a small dot exactaly where
the jerks happen.
I do remember there being some issues with drawing with polylines or
spines or something like that. Maybe this is that issue?
Should I draw in Corel instead and export as a .plt file?
