Human: Evolution of www.thingiverse.com/thing:80472 by Kolergy. Thanks to him. Magnetic platform is an evolution too from a Thingiverse original design, but I can't remember where I found it. Sorry for that and thanks to the creator. For Jhead 3mm use. May be the holes size need to be adjusted for your printer. Works fine with Mega2560 + Ramps + Klipper. Modification of Kolergy's Enlarged Rostock. Thanks to him. The magnetic platform also comes from Thingiverse, but I can no longer find the original design. Thanks to the designer. The modifications aim to have more rigidity once the machine is assembled. The vertical carts use neither bushing nor ball bearing, with direct plastic/steel contact 12mm in diameter. You must perform a pre-assembly run-in, but the lifespan is largely sufficient and the play is weak or zero. Holes are provided for lubrication (oil). A small tip for the run-in: use "Miror" for copper maintenance if sliding is too hard. The belts are 2.5mm, so the tensioners are also. The hotend is a Jhead for 3mm filament (3mm is fairly rigid, but it works). Nema17 motor in 400steps. The drive is ensured by classic: mega2560 + ramps. Attention: firmware klipper is almost indispensable! Otherwise, it's too slow. Update 18/02/2019 Add some photos and parts.
