Maybe a solution for many problems

Ole Johan Aanestad

I have successfully knitted about 30 scarves, and I am knitting "thin" - 2/48 single tread.
I actually have successfully knitted 2/60 (50/50 cashmere/silk) - amazing 45 x 200cm - only 190 grams.

Then, for some reason, the machine just got "mad" - I couldn't even start to knit, all was "f... up" - I was mad as well.

The feeders was "meters" away from the needles, had no chance to pick them up, ...I mean NO WAY!

To make a long story about what I have used the easter to, yes, my head down in the Kniterate....

I found out it's very critical that the possission from the feeder to the needles are way more "sensitiv" then I have evet dreamed about, so let me short try to explain with this drawing:

Numbers referst to the feeder.
I made a simple knit, just with a "start" knit, deleted the 15 first ROWS, and stopped the knit as soon it have knitted some needles, lets say 20-50.
Then I checked how the feeders possission was regarding the needles, and I adjusted (the part on top of the feeder)

so the possission become as number 2 in the drawing below, meaning, that the tread "goes true, needle 1 and 2 (from left to right on the drawing)
I did this, with all feeders, changed the "start-file" to use feeder 1, 2, 3, 4, 5 and 6 (waste yarn) - and I did the adjustment both "forward" and "backward" - and do not relay on that the possission will be the same on anyone - at my machine they are all diffrent (witch surprice me as well)
Then knit the full start, stop it at the end, check that every (every secound) needle are knitted correct, if all ok, continue to chech the next feeder.
I suggest to use a strong color, I used yellow as its easy to see)


1. The feeder are actually looking good, going true needle "1", it's knitting, but leave random missed needles, mess up the "bindoff".
2- The perfect solution, from the feeder, true needle "1 and 2", never miss anything, finishing perfectly, perfect bindoff.
3. Almost as good as 2,  do not miss needles,works very good fixing the treads in the (tread cutter (well, never seen it cut the tread)) but mess up the right edge (no matter what tension)

I am surpriced how important so perfect possission are, ..maybe not that it's perfect, but that what seems to work well, makes another "problem, like if you use 3...it mess up the right end, no matter what tension.

So to all who have issues with missing needles, bindoff, this solved all my problems..even why it got "mad" will be a mystery...

PS! I also had a issue, where in the middle of knitting, the machine suddenly did a "by pass" without the needles being "activated" so it drag the tread stright over the knit, like it missed all.
I have asked Gerard, if it can be that the SD-card that came with the machine are to slow (only a issue if the SD-card works as a "harddisk" and read directly from the SD-card during knitting.

I cahenged my card to a faster card, and have never seen the issue after.

But this information, I can not confirm are correct before its confirmed that the machine uses the SD-Card as a "harddisk".

    I think this is causing me issues too. Can you explain how you tested which feeders had issues? Are you saying that you tested every needle, then every other needle, then every third needle etc with each feeder?

    Thanks

    Hi Laurence
    I will make a video for you, showing how (you may mail me at olejohan@olejohan.com)

    I can try explain here:
    I started knit with the first feeder - then I stop the machine in the middle of the knitting row, so you see the tread from the feeder and how it's "lane" true the needles as on the drawing abow.
    Then I adjusted the (I not know what it's called - but the part on the first picture) so the tread goes true needle 1 and 2 as (green) on the drawing.
    What I discovered are that if the tread are to low, it can miss the needle, the same if it's to high.

    I repeated that on every feeder, both going right and left.

    - I have just also discovered something om my unit that may can cause some issues, but I am not sure yet.
    What I discovered, ate that the beds are not aligned (from factory) there are a gap between the beds on the left side of about 7mm, while it is 11mm on the right side.)
    I not know if this are the result of me having "problems" with the "start-up" as yarn very often not go down (it clumb, and I have to clean out  - trying again and again, until a "lucky moment")
    I just can imagine that 7mm gap, may be to small and 4 mm difference (left/right) I imagine also will be a difference how the needles catch the yarn from side to side.
    The funny thing is that I can't see loops differences on the finished knitted product.
    Maybe Gerard-Rubio can have a aswer her?

    Yeah (???) - someone just finishing the Ph.D education?

    Hi Ole,

     

    Just wanted to say that these changes seemed to have resolved 99% of my issues. We had guidance from Gerard to make the same adjustments and the samples seem to be working in the most part,

     

    Thank you so much for your help with this.
