Basics
- OSE's Fork of CircularKnitic, the open source circulate knitting machine
- Code available on GitHub https://github.com/OpenSourceEcology/circular_knitic
- Test build - original size - User:Dorkmo/Builds/CircularKnitic
- Test build - sock size - User:Dorkmo/Builds/CircularKnitic-Sock
Goals
Needle Accomidation
- Long tails
- Bent back tails (postponed)
- Test 3D printed needles (postponed)
Fabric Spool
- Apply constant tension on fabric (postponed)
- Roll onto spool for easy handling and storage (postponed)

CKpM.scad "mountain"
- takes a long time to render, have to be patient, possibly a few hours
- need to set a minimum thickness of the mountain based on distance between bolt holes
- add center inlay groove for middle plate to sit in. hold mountain in place.
- possibly move/change mounting wings from above c2 to sandwich between c2 and c3 with same height as p8
- would this cause collission with p3 base bolts and pM mount bolts?

To Do
- make motor's gear optionally 3d printed or laser cut utilizing Pololu hub
- make an optional plywood cnc cut board that pairs with c1 table top
- calculate angle from OD of needle's hook at lowest poistion to the top of p4 base
- what is ideal? +45? force pulling loop away from latch minimized at lower angles?
- thread feeder hole, measure knot diameter
- maybe 4-5mm? need to accomidate end/begining thread connecting knots
- yarn stick holder etc
- tensioner etc
- printable bowl to hold bag of water on fabric tension plate?
Test
- determine smallest diameter machine
- what needs to change to go smaller?
- create a minimum c1 table top dimension?
- do some of the parts render incorrectly if over 180degrees around circle?
- what needs to change to go smaller?
- test larger machine size
- what are the standard diameters of fabric
//number of "p2" parts around circle //Jan2019 //small p2number=8; //12 //36 ///36 //12 //8 //number of needles mounted on each "p2" part p2needles=7; //5 //10 ///5 //5 //7 //number of "p3" parts around circle p3number=2; //4 //18 ///4 //4 //2 //number of "p4" parts around circle p4number=2; //4 //18 ///4 //4 //2 //distance from the inside face of one needle to the next needle2needle=9.25; //default=14.35615 //try 8.414 //13.5334 //9.25 pMgrooveturnR=10; //radius of upper curved path in groove //14 //10 pMgrooveturnR2=7; //radius of lower curved path in groove //7 pMgrooveturnR3=7; // radius of entrance curved path pMp7X=2; //half of length of plateu of groove. preferably whole number //3 //2 pMp3X=2; //length of lower plateu of groove //2.5 //2
- lower length of groove7 and groove3?
- might change back to M2 or M2.5 sized bolts
Known Bugs
- Only 45 degree angle works for mountain groove path
- curved paths break, something in the sin/cos is not correct
- needle2needle value doesnt seem to be rendering exactly as was measured on original stl
Future Work
- create design so that mountains are stationary and needles rotate
- add multiple mountains, yarn can remain stationary
- output fabric spool must rotate too
- RotoKnitic v19.01
- sock heels
- mechanism to raise needles to a position above mountain so they can skip loops
