Hi , I am again looking for information on a DXY 800. I have one with both
serial and parallel but no information regarding drivers and any other info
that is relative to it, "any luck". If all else fails I may rebuild it
using a 5 axis driver board I am waiting on. The only problem I have is it
is a MACH 3 CNC activated thing and I don't know If I can plot with it. I
have a HP pen holder and solenoid to replace the Roland one. One of the uses
will be for board layouts using the plotter frame and use the electronics in
a better frame and steppers to engrave panels.
Many thanks,
Don....
