Since this question I completely redesigned the printer - now using dual Y-axis steppers, and a single Z-Axis stepper to lower the print bed. My Y-axis motors, I wired in series and it seems to be working perfectly (mechanically - haven't actually printed anything yet). I'm not sure what the downside of wiring in series is, really - only low torque, but it would seem that can be designed around.by JasonStonier - Reprappers
I've been designing and building a cubic 400x400x500 printer for weeks - mainly reinventing the wheel because I thought I could do it better, then repeatedly discovering that I couldn't. It's running on a RAMPS1.4 with Arduino Mega, Marlin 2.0, and Octoprint. X- and Y-axes are on the top face, and the print bed is on the Z axis (cantilevered, with one lead screw) - vaguely like an Ultimaker 3.by JasonStonier - Reprappers
Great advice - thanks for that. You gave me some confidence to keep going with that motor and I found that the driver board was dead, AND that there were combinations of cables and motors that just didn't work - I now have all the axis motors working. My next question - and I have searched for this but I suspect I don't know the right terminology to search for - the X and Y motors are really qby JasonStonier - Reprappers
Arduino Mega with RAMPS 1.4, A4988 drivers, 12864 LCD controller, and NEMA 17 motors. Marlin 2.0.7.2 firmware. A while back I bought a cheap Anet A8 printer that never worked well due to its terrible tolerances, so I built a frame with decent linear sliders and transferred the motors and some mechanicals over to it, with a new RAMPS 1.4 board and Arduino Mega clone.

Hi there, Well, I am looking at this forum! I'm just starting to research building a reprap, so I am at very early stages of the process. I'm hoping to do it as a winter project this year. I'm in Poole. Jasonby JasonStonier - United Kingdom RepRap User Group
