I've got a Shopbot Buddy with the 2.2 HP HSD spindle. I have an intermittent issue where the Shopbot 3 control software hangs when I turn the key to turn the spindle off during a tool change. Seems to happen after the tool change when I turn the spindle back on.

If I kill the process for Shopbot 3, it still won't restart unless I unplug the USB hub cable and plug it in again. It happened on an old laptop (which had other issues). I bought a brand new fairly high end laptop and reinstalled everything - still does it. I'm using the USB hub (as recommended). Moving the Shopbot USB connector to another port on the hub helped for awhile - now it does it again. I monitor the USB speed regularly in the diagnostics screen and speeds seem to always be acceptable.

Anybody else run into this ?? Thanks !! --Pat
