The design of each of the two axes revolves (sorry!) around the use of a NEMA-17 stepper motor with a 27:1 planetary gearbox, driving into a harmonic reducer gearbox. Harmonic drives (aka strain ...

3D-printed gearboxes are always an interesting design challenge, especially if you want to make them compact. [ZeroBacklash] created a little strain wave gearbox (harmonic drive) for when you want ...

On display: SoftStep stepper control Key features: Technology essentially converts driver data into ultra-fine microstepping (256 microsteps per motor step), ramping speeds up and down between ...

Disclosure: I have seen a set of 3d printed x-y motor mounts, like these from jimmit on thigiverse, but no 3d printed z (up-down) mechanism. Here’s is my prototype z-axis mount (right). It is the grey ...

Ultra-compact, lightweight and stepper motors with improved torque and low backlash. Oriental Motor is pleased to expand the PKP Series stepper motor product line-up with the introduction of a 51 mm ...

The question is: how to ‘cnc’ a manual Sieg X1 milling machine – the so called ‘micro mill’ that comes out in so many guises including the Clarke CMD10 featured here, available from Machine Mart, but ...
