A general summary of project progress as of February 5th, 2022.
Mechanical
Built and assembled a completely 3D printed version of the bracket and hot end gears to see if the geometry was feasible. Followed this up by using learnings from that prototype to build a version using aluminum shafts for better movement and stiffness. Learned several things as a result of these prototypes:
- Geometric tolerances for 3D printing fits
- Shaft sizing
- Bending radius for the bowden tube
Electrical
Proceeding as planned (see the last post).
Software
Firmware
Sticking to plan (see the last post). Some more investigation of the appropriate place to modify Marlin is continuing.
Slicers
Sticking to plan (see the last post).
