This is the top board (only) from a Baldor NextMove ST stepper control board as used in my ScanTek 2000 ScanMill (A rebranded Denford Micromill 2000). The dispatch date on my mill was 2005, and you will note that this board has the USB input as well as the serial port input.
I removed this top board from the lower stepper motor driver board and converted the machine to LinuxCNC control via a parallel port break out board. The machine and bottom part of the card works great, and I can only assume this topcard is also perfectly operational. You can view the machine bootup sequence (with ESTOP error flashing on the topcard because I had not yet defeated the front panel keyswitch) at this Youtube Video: https://www.youtube.com/watch?v=qXW6EgVi-rg Sticker on the microchip reads: NST002-501D S/N U0505270018
Auction is for the top card pictured and the two mounting spacers and screws only, does not include the bottom stepper controller board or anything else from the mill. I also purchased a ScanTek lathe and plan on converting that over next, so I'll eventually have another one from the lathe for sale.
