Hi Tom:
I don't know whats causing the slowdown, check to make sure the pulse
width is not too high. If set to 0 or 1, the slowdown should not occur, if
set too high, this may cause that type of problem at higher speeds.
The incr. jog speed is at the current feedrate set.
I'll check out the X axis, you mean it doesn't reset in which way? to zero?
or the offsets do not remove?
Thanks,
Art
