After few months usage of the current MK2Clone with good results, I’ve decided to go further and create a… MK2Clone Revision 2 (r2).
All the parts was reviewed – modifications, some smallers and few biggers was made. There is a new frame, designed to be lasercut from 10mm plywood. Spool holder taken from MK3, adjusted to fit 10mm frame. Parts refined to be more easily printable. Fixed a lot of misalignments in the stls due to differences in mechanical parts.
There will also be a lot quieter printing, thanks to Trinamic stepper drivers and quiet-enough SUNON fans. Additionally, filament runout sensor integrated with extruder body – no more ruined prints due to end of filament.
Unfortunately, the printer will be not as cheap as the first one. Trinamic stepper drivers are more expensive than the standard a4988. Original E3D Hotend, bigger heatbed, even the SUNON fans – all that parts will make the printer far more expensive. For the people looking for cheaper version, there will be still a option to use cheaper parts, I’m planning to publish a list of cheaper replacements.
Additionally, there will be a full guide describing how to build the r2 step-by-step, with photos.
All the parts for r2 (it’s still beta!) can be found on MK2Clone on GitHub in master branch (the master branch should be called dev for this repo ;)) – https://github.com/q3ok/Prusa-i3-MK2-Clone/tree/master
