-It has a standard needle bed with 200 needles. ​2-colour patterns ​etc can be obtained ​using the punched cards or using the buttons below where the punched cards are fed in. Patterns ​can be maximum of 12-stitch wide repeat.+Theoretically you can programme ​2-colour patterns ​with a 12 stitch wide repeat ​using the punched cardsor by selecting ​the buttons below where the punched cards are fed in. However this mechanism is prone to selecting the wrong needles, which will cause glitches in your pattern.

-The machine is not yet working perfectly OK. It is working well enough to knit something in plain colour, or stripes (so long as you have the right tension settings ​for your yarn). It is not yet working properly when knitting patterns using the punched cards or buttons.+There should be really useful box somewhere which contains instruction books and some accessories ​for the machine.
  
-All of the following ​yarns are in the drawer of knitting ​machine ​accessories (3rd drawer down under the Wera screwdrivers):+When getting set up, it is important to set the correct tensions for the thickness ​of yarn you are using. The thickest yarn the machine seems happy with is DK weight, and even this can sometimes produce bad results. Better to use a lighter weight yarn. Some yarns have been tested on the machine, with the following results:
  
-  * Red yarn (probably DK weight, from West Yorkshire Spinners ​'100% Wensleydale Gems'): Set tension dial to max (above 10) and yarn feed dial to 3. This produces ​a gauge of 22 stitches and 32 rows over 10cm. +  * West Yorkshire Spinners 100% Wensleydale Gems: Set tension dial to max (above 10) and yarn feed dial to 3. This produced ​a gauge of 22 stitches and 32 rows over 10cm. 
-  * Off-white (not fluffy) yarn: Set tension dial to 9.1 yarn feed dial to 3. Gauge not measured. Works ok as second colour to red yarn above. +  * West Yorkshire Spinners ​Signature ​4-ply: Cast on successfully with tension dial on 5, but became a bit tight 12 rows later, so changed up to 8, which was fine. Yarn feed dial was set to 5 the whole time. This produced ​a gauge of about 28 stitches and 37 rows over 10cm. 
-  * White brushed thermal (slightly fluffy) DK weight: Same settings as red yarn above. Gauge not measured. +  * Katia Panama ​cotton: Set tension dial to max and yarn feed dial to 3. This produced ​a gauge of 26 stitches and 30 rows over 10cm. Is prone to not fully completing the knit on a couple of needles at either side of the work on the first few rows, so you may need to manually check and rectify. This is probably because the tension is still a bit too high even on the lowest setting.
-  * Self-striping rainbow yarn (this is West Yorkshire Spinners 4-ply): Cast on successfully with tension dial on 5, but became a bit tight 12 rows later, so changed up to 8, which was fine. Yarn feed dial was set to 5 the whole time. This produces ​a gauge of about 28 stitches and 37 rows over 10cm. +
-  * Purple and acid yellow cottons (probably DK weight, ​Katia Panama ​brand): Set tension dial to max and yarn feed dial to 3. This produces ​a gauge of 26 stitches and 30 rows over 10cm. Is prone to not fully completing the knit on a couple of needles at either side of the work on the first few rows, so you may need to manually check and rectify. This is probably because the tension is still a bit too high even on the lowest setting.+
  
-==== Further debugging ====+It also comes with an additional carriage for doing lace, but this has not been tried yet.
  
-There are still errors in needle selection occurring when using either ​punched card or selection buttons. When moving pins by hand on the bed, errors do not occur (i.e. it's not the carriage at fault). The solenoids engage correctly so it's not likely to be them either. Most likely is the the 12 plates that run along the back of the needle bed (that push pins forward via a raised tab) are sticking together when they lift up and push the pins forward. Some lubricant has been applied to see if this will help prevent the sticking. Failing that it might be a question of disassembling this part of the machine and cleaning it.+==== The problem with the punched card mechanism ====
  
-Also the sponge bar will need glued down at some point.+Needle selection errors occur when using either punched card or selection buttons. When moving pins by hand on the bed, errors do not occur (i.e. it's not the carriage ​at fault). The solenoids engage correctly so it's not likely to be them either. The mis-selection seems to be caused by the 12 plates that run along the back of the needle bed (that push pins forward via a raised tab) - these stick together when they lift up and therefore push pins forward when they are not supposed to. The machine has been disassembled,​ cleaned and lubricated but the problem remains.

-It would be nice to be rid of the 12 stitch repeat constraint and instead have every needle individually controllable. This would require hacking, perhaps (servos, cams?). Ideas are welcome. It is possible to buy electronic knitting machines that bypass this constraint and are known to be hackable, but these are 100s of £££ ​(although if people fancied a pledge...). +It would be nice to be rid of the 12 stitch repeat constraint, and the fault needle selection mechanism, ​and instead have every needle individually controllable.
