Sers Chri! Hat sich dein Design denn bewährt? Falls nein, wo gibt's Probleme? Und könntest du die Quelldateien sharen? Ich würde gerne folgende Dinge anpassen: - NEMA 17 - 5mm Schlossschraube mit Endgewinde für das MK8 - 2.85mm Filament

Nice Job! I'm working on something similar for Nema14, but moving away from the hobbed bolt. Keep up the excellent work.

<p>Hy Apelpapa, as long as the Wallace has 50mm mounting holes and a topmount fit it should fit.</p><p>The M3 wormdrive will be needed for locking the small gear, it should not be longer than 4mm as there is not much space at the body</p>

The lightest useable may be the SM35HT27, its spec is 1.2kg at 110 gram weight, but don`t know hot to get them. i have a SY35ST28 with 1kg and 130 gram, but never had time to test it with it, maybe i will try it out some time.

sorry i don`t know the OZ values i only know the kg. As strong as possible, my Nema`s are wrong labelt (picture), they are SM35HT33 with 1.8 kg/cm holding torque and ~175gram.(rated 180 with cable) The gear has a ratio of 1:4,5 the effective force is about 8,1 kg/cm with them. As people also use nema 17 with 4.4kg/cm direct drive you should at least use a nema14 with 1kg/cm but the more the merrier. (1.2 1.4 or 1.8kg)
