You could do it with a breakout board though - something that you'd plug the RAMPS shield into that has a DB25 connector on it, correctly connected to rows of pins that imitate the mega's. This might not be workable without some sort of switch - leaving the mega's pins directly connected to the parallel port may not be the best idea. Sry for my english and thanks for any reply.Įdited 1 time(s). Have you guys any idea how it could work? When I measure the voltage between the pins is just 1V although it is 5V on a simple test LED circuit. I've tried to wire the parallelport correctly to the shield, but nothing is working at all. As I want to do printing AND milling stuff with the same machine/electronics and I'm comfortable with mach3, I'd like to add the possibility of parallelport communication to my RAMPS electronics. It works quite well both with replicatorg/5d firmware and hydra-mmm firmware/host software. The last months I've built a repstrap (without extruder) with RAMPS electronics. I knew, i have to build such a cool machine. This summer I came along the whole reprap stuff and was blown away. My brother, father and me have built 3 CNC-machines the last two years and still can't get enough of them. I'm from Switzerland and passionated hobbyist (don't know if this is the right word in english). As this is my first post I'd like to introduce myself and say hello at first.
