So my big problem is that I’m stuck on which specific stepper motors to buy, and what specific power source to buy for use with the following: Arduino Mega 2560 (clone), ramps 1.4 (clone), five A4988 stepper driver (clones), a 12864 lcd display for RepRap (clone), I have 6 mechanical end stops (also clones) for the ramps 1.4, I’m going to use an e3d v6 hot end (clone), I plan to make a Hypercube style frame with two z avis bed motors. I expect to build it 30" x 30" x 48 or 50", and I hope for a 24" square build surface. This is my first post, I’m not so good with electrical theory vz can someone please suggest exactly what I need? Thank you-
