Hello
I'm building a 7 x 9 feet (2 x 2.5m) "drawing machine". Essentially a very light duty belt driven CNC with a pen instead of a router. I need it to be FAST (2-3 feet / second)
For this kind of machines, I have used in the past OpenBuilds BlackBox, but this time I want to use either closed loop steppers or servos for which the BlackBox doesn't work. The reason is that the machine will have to run nonstop for days and any missed step will destroy the final drawing.
Can anybody recommend a setup consisting of a closed loop or servo + controller that accepts G-code?
Also: The longest wires to the motors will be 5m - 16 feet. Can that be an issue?
Thanks!
