I have a similar router, larger, more rigid model than that. I have the DSP controller and use it. It is a very nice control, very reliable, machine easily cuts at 800 in/min, rapids over 1200. Yes, there is no graphic display on the control, but if you are so inclined to need to see one, you can leave it plugged in to the USB on a PC and watch the thing on screen. I use my CAM for the graphic cut display normally. Storage is a huge 32 meg, I have ran files as large as 4.2 meg, this is a text file, remember, and I have run it non stop for over 100 hours without problems. Servo drives are 90 volt on mine, which is part of the reason it has good speed. I have never had a problem with CV. I imported mine directly from the factory in China. I can help with issues, questions if needed, let me know.
