    I never machine knitted, and read that other knitting machines usually need an accessory (e.g. a ribber) to make purl stitches, or operators stop the machine and reverse each stitch they want as a purl by hand.

    Now, most of my knitting works have patterns that combine knitting and purl stitches in the same row. Is the kniterate machine able to also do these? I am trying to understand the K-code instructions and I still have to catch up on machine knitting terminology, otherwise I would probably be able to answer it myself.

    If the machine can purl, can you please tell me what the sequence of K-code instructions is to do “k1 p1 k1 p1”?

    Thanks in advance,

    Not an official answer, just a backer and machine knitter. Yes the machine can knit purl stitches, it has two set of needles, one does knit and one does purl, and the machine can transfer stitches from one bed to the other (and not just directly across, the beds can shift before transferring from one bed to the other.

    There is a Kniterte channel on YouTube. This video ( https://www.youtube.com/watch?v=HdiBEAvNMMU ) shows knitting on both bed, transfers from one bed to the other and decreases.

    there are many examples of knit products on their website and instagram feed showing combinations of knit/purl (anything with ribbing) and transfers (like cables).

    Who else likes plated cables?

    I’ll leave it to someone official to correct me on the K-code. You most likely are not going to have to know the details of K-code, the design software will hide those sort of details. For instance you enter an image and the design program figures out the K-code to knit which color yarns on which needles. If you want 1-1 ribbing, you’ll likely select 1-1 ribbing from a menu. Some folks have queried around the K-code because they want to write their own programs to potentially do more than the provided design software will allow.

    not sure what happened, my speculative attempt at k-code disappeared. This is pure speculation, no actual experience on the machine, likely wrong but hopefully gives you an idea of what a direct answer to you question would look like and make you thankful, you won’t need to do this sort of thing unless you really really want to. You’ll hopefully just choose 1-1 ribbing from a template.


    assuming carriage starts on left
    the first batch of KRR, KFR, KRL, KFL specificities knit odd number needles on back bed, purl even number needles on front bed.
    The KNIT saws ‘knit’ left to right, then right to left
    the second batch of KRR, KRF, KRL, KRL specifies transfer even needles to back bed moving right-to-left, don’t transfer anything left-to-right.
    the TRNF moves the carriage right to left, transferring the specified needles, than moves the carriage left-to-right to return it to home.
    this would knit two row of 1-1 ribbing. knit 1 purl 1

    Hi @megfault, hi @mark,

    Yes, the machine can do knit and purl stitches (and many more). The two needle beds create both knit and purl stitches, depending on how you look at your knitted piece. To see the pattern coming out of the machine with its right side towards you, you would use the back bed to create the purl stitches, i.e. the plated cable @mark posted from our Instagram. Those purl stitches are actually knit stitches on the backside of the pattern. The reverse side of each knit stitch is a purl stitch.
    Another example would be a knitted tube (you knit consecutively on both beds, like knitting in the round), the stitches inside the tube are purl stitches and outside are knit stitches. So the needle beds always create the purl stitches facing each other.

    I hope that made sense. πŸ˜€ Let me know if it doesn’t.

    Regarding the kcode, @mark described it right. Thanks. πŸ™‚
    1 equals ‘knit’ and when you knit on the back bed, you create automatically a purl stitch when you look at it (so the backside is the knit stitch view). 0 equals ‘miss’, so no needle gets selected.

    The kcode won’t be needed anymore when the software is fully developed. It will generate the patterns you design into kcode by itself. So don’t worry if it doesn’t make sense to you. The software will be easily usable for everyone, including pre-designed bits like ribs, cables etc. to draw on. When you get more advanced with the software and the machine, you can use the software to program your own stitches, like a blank canvas.

    I hope that is helpful.

    Thank you all for the replies, I am relieved it can purl.

    I am a software developer myself, and would like to generate K-code programmatically, so the instructions sample was helpful. I found a really interesting research paper describing how to transform 3D models into knitting stitches, so it would be nice to translate them into K-code and see what weird shapes I can make.

    I can’t wait to get my machine!! 😍

    Assume you are talking of the Disney Research paper on 3d-knitting, including links for those not yet lucky enough to have seen it.

    Disney Research Creates Compiler for Industrial 3D Knitting of Apparel & Structures


    Saw note about a week about about the big industrial knitting machine and the winners of a design competition. (Perhaps something Kniterate or its user’s can maybe organize our own version someday)

    Hopefully Kniterate will help accelerate the availability of versions of industrial tools like Apex for the home/small business user

    Well I can dream

    @mark That’s exactly the paper I was referring to! πŸ‘

    Guess I have been asleep at the wheel, open source version of 3D mesh -> machine knitting pattern has been available at github

    See weekends disappearing in my future

    I was able to download the code from github and get running on my MacOS machine without too much trouble.

    the paper mentions:
    “Our system writes patterns in an intermediate low-level knitting
    language, which is further translated by backend code into the
    Shima Seiki KnitPaint β€œdat” format. However, nothing in our system
    relies on special features of Shima Seiki machines. In theory, one
    should be able to build additional backend translators to support
    any knitting machines with two beds and transfer support.”

    looking forward to that additional backend translator being written (hint, hint)

    from the lack of easy-to-use software

    The paper cites Kniterate

    “The hardware landscape is already
    starting to change: β€œKniterate,” a consumer-level industrial-style
    knitting machine, was recently funded on Kickstarter [2017].”

    so perhaps that additional backend translator is oh so much closer to being real

    relatively small set of commands generated in the example used to illustrate process

    drop {f|b}N eg drop f24 ; drop b11 f–Front b–Back
    inhook C — Carrier
    knit {+|-} {f|b}N C — {+/-} carriage direction
    miss {+|-} {f|b}N C
    outhook C — Carrier
    rack {-}P — number of postions to rack
    releasehook C — Carrier
    tuck {+|-} {f|b}N C
    x-stitch-number N
    xfer {f|b}N {f|b}N — from to

    sadly missed out on 2019, have a calendar reminder to look for details of 2020 Symposium on Computational Fabrication. Will have to also keep my eye open for Conference proceedings.
