deliver extreme accelerations to the table, so corners may get rounded off a
bit. Is that a big concern? It totally depends on the workpieces
you'll be making.

I've got some pieces here where I could see this effect :

///Mine does this as well. But it's Z that does it because it will not respond as fast as X and Y. When I'm running Delrin (acetal) or UHMW at like 60 ipm and plunging Z up and down for different elevations, I have to watch that Z is fully retracted before X and Y take off. The remedy I use for this on Z retracts is simply copy and paste the same Z + move as the next string and then it will retract completely prior to X and Y taking off or set the R-plane higher. On 3-D surfaces I just have to slow down to like 25 or 30 ipm. X and Y I've never had this problem at any speed that I recall. Removing the G64 constant velocity mode command may help with that also.
