I have a small (21"square) Magnum router sold new by Denford in 1996.The machine is in good condition and seems to work fine, but the PROCAD cadcam software does not seem to be very user friendly. Is it possible to use a modern cadcam system with the inbuilt controller or is it a rebuild that is required? I am aware the these machines were intended for the educational market, but I (a 63 year old student!!!) am struggling.
