When mu machine is working and I press the "pause" button (yellow) it stops immediately without a deceleration ramp.
It causes steps loose, a lot.

You can see it here www.fxmodel.it/loose.wmv ... ehm sorry I imitate the bad noise with my voice in the video ehehe.

I tired with 2 different pc, one is a celeron 1ghz the other is a p4 3ghz, in the lastone the "drive test" graph is flat absolutely flat.

Thanks Faby
