Ramps 1.4 is it possible to have almost everything running with repetier?
I built a my first 3D printer last month, and after several upgrades it is mostly a prusa i3...
I have two MK8 extruders (thermal probes, steppers, and heating resistors on both), servo and switch for z-probe (on Z-Max), I also have a cooling fan for cooling extruded material (with PWM), and a Full Graphic Smart LCD Controller with SD card.
the problem I have is I can't get everyone to play together, and at this point I don't even know if its possible to have all those things going at the same time without interfering with something else as far as pins go.
I'm not sure if anyone has made it work without the need for another board via I2C or have used multiplexing, but any ideas or links would be great!
