This OpenSCAD file describes my version of a circular knitting machine. This is an original design, but some details and ideas were obtained from various sources . User RoundandRound (https://www.thingiverse.com/RoundandRound) very gracefully produced an assembly guide which can be found in the files section.
Design criteria:
- Bi-directional (for heel and toe knitting);
- Minimal moving parts;
- Low friction;
- Minimal contact of yarn with printed parts (no snagging);
- Minimal sanding;
- Low cost: budget under 50 Euro
The machine is driven by side-by-side pullies with a 2GT timing belt to reduce friction. Also the machine runs on three ball-bearings, using 4.5mm steel BB's as balls.
There are 2 push-up cams, leaving the needles normally in the up position. They can be pushed down to do maintenance; eg. to pick up dropped stitches. This eliminates having to use mechanical "flippers" to push the needles up. (Usually the needles are pushed up (to clear the needle latches) just bef
