A single motor, dual leadscrew setup for a Hypercube Evolution.
you will need
2x 20t x 8mm bore toothed pulleys
1x 20t x 5mm bore pulley for the motor
1x 20t x 3mm smooth idler pulley
Your choice of pitch of 8mm acme lead screw, I use 2mm pitch, 4mm lead screws.
4x M3 x 12 - 15mm, bolts for bearing holders
1x M3 x 25 for idler pulley
1x M3 x 15mm bolt for back of idler pulley support
Basic M5 mounting hardware for 3030 extrusion
1 extrusion the same width as your x axis extrusions
1000mm belt for a 300mm x 300mm printer, I Just loosely calculated belt length by doubling the X axis extrusion length, then adding a minimum of 100mm. for example, my X axis extrusion is 420mm, double that gets 840mm, add the 100+mm and you get 940, I just rounded up to 1000mm for a little extra. its better to have a belt slightly too long, than too short.
