I have just got my CNC router working really well with V-Carve Pro at school, now all of a sudden the DSP controller (RZNC 0501) is playing up. When I plug in I get a message which quickly flashes on the screen - "Is boot loading .......... please wait", but nothing happens. I feel I may have accidentally re formatted the system or something. Does anyone have any ideas what I can do to fix the problem? Using the DSP controller with USB stick is perfect for me because students can do all of the prep work and just give me their USB stick when ready to do the machining. Hence, I don't really want to go to a breakout board and Mach 3. for example. Any help would be very much appreciated
