great idea, I didn't even realize it would accept fractional values in that block.
SO IT GETS WEIRD.
with backlash compensation %speed set to 0.1, it very slow initiates its BC compensation move, which at 0.1 is very slow, then as soon as it gets to its rapid it hangs.
I rewrote the program to remove the x move ENTIRELY, and it works fine.
HOWEVER, at 0.1%speed I did notice that as its doing its backlash comp move, it creeps very very slowly, then takes a sudden jerk right before it hangs the motor, I will study the motion a little better and report back. Very odd.
