how to get started? #1

Open vivienne opened 3 years ago

vivienne commented 3 years ago

hi! thank you for starting this project, it will be really nice to have something open source working on my sk840.

how stable is this (does it work) and what do i need to do to get started? i don’t see any related docs on the ayab website so i’m not sure what i need to do to get this up and running. thanks again.

Hey Vivian,

It was never really finished but because I wanted to make it a self contained device.

It was working though in the sense that I was able to knit a pattern line by line being sent through ayab software (to clarify i have nothing to do with ayab and they don't know about me, but through the beauty of open source was able to use their stuff).

I barely remember what state it is left at, as last time I worked on it was like 4 years ago. I'm happy to take some dust off and write some documentation based on what I vaguely remember.

The most important part is that you actually need to build the shield for Arduino. The schematic is at https://github.com/romkal/silverduino-board (it is KiCad schematic, not Eagle like written). There is openscad project with a box i wanted to 3D print for it.

On wiki there is a short description telling how to talk to the machine (what signals you get on the plug). I guess this took me the longest time to figure out.

Some pictures of what state it was at: https://photos.app.goo.gl/ExRQWaUi5CdJAmRw7

(I'll add the latest state tomorrow if you want to see it).

Hi both, I'm following this thread because I'm also super interested in hacking the sk840 as well. Nice to see you got it to work with a breadboard first - I might give that a go, before attempting your idea of a custom shield. I guess all the requirements/schematics are in the kicad and that description in the wiki, or would I need any other info? Thank you!

I'm working on putting a couple of these together for a friend - @romkal which power supply did you use? 16v 1.5a? I don't have access to the knitting machine so I just want to double check I'm doing everything correctly and won't blow up someone elses thing :)

e:Thanks for putting all of this together, btw.

I literally used this power adapter, but simply, because I had access to it already. It is 16V 4.5A. I don't really know the power requirements of the machine, but it worked for me on that. [image: PXL_20220119_194931031.jpg]

Hello! Thanks for starting the project! I'm also in the process of hacking my SK840. Currently trying to know what exactly are the signals sending between SilverLink4 and the SK840... it's only been a few days, but I'm hoping eventually I can have a realtime interactive signal sending from the computer to the knitting machine. I haven't tried your code yet, but from as far as what I understand, the silverduino replaces the SilverLink4 and the software side is using AYAB?

romkal commented 2 years ago

Sorry for missing the message for so long. Yes. You can say that this is a replacement for SilverLink4, although I got my hands on the service manual for the machine with description of SilverKnit PE1 module and was using this as a reference.

Here is the doc https://drive.google.com/file/d/0B_WjRxc0u_9NTnFMay1KS3VIRlU/view?usp=sharing&resourcekey=0-fuSC-Pz1pstmIIgJcETs2Q although please ask for access if you want to get it.

please could i have access?

ca3rine commented 2 years ago

Thank you so much! I've recently hooking up the logic analyser on SilverLink and is one step away from creating a board and script to send signals. I've requested to access the file, waiting for permission!

@romkal there is a current discussion of Silverduino on the AYAB discord, it would be great if you could come over and say hi! Here's an invite link; https://discord.gg/QdAK5ACf
