Recently our V3 started giving us issues and after trouble shooting we determined the Mechatronics driver was the culprit. We ended up buying a new card with the Toshiba 6600 chip, and set the setting like our old card was, but now the motors don't work. We are pretty sure the CNC USB card is talking to the new driver as the work led's show traffic on all 3 axes. I have tried multiple settings on the current and step setting to, but am unable to ever get any power to the motors. Here is a link to the card we have: http://www.ebay.com/itm/CNC-Router-...303895?hash=item542cb4ded7:g:xyUAAOSw3mpXL8ol

I hope someone out there has been down this road!
