Solved Thinking of going CAN bus. What's the best option for my setup?

[Maddog]

Oh, I thought you said you tried it.
Like I said, I have used almost every CAN board on the market. USB is way easier. I really don't know how you cannot see this. I am not going to argue with you since you have your mind made up but I would still suggest trying it before making your opinion.

I created a Poll on the Voron USB/CAN Discord channel. https://discord.com/channels/460117602945990666/1076243803947667516/1237732659103268895

Looks like in your poll you are the only one supporting USB instead of CAN.

Yeah, that seems crazy to me but okay, I guess people like CAN bus better. To each there own I guess.

So I have now added to the mass of people that need to research can bus or usb
Since there do not seem to be convincing arguments yet that swing either way, I think best to keep on researching on a very broad range of platforms to see what are the general feelings out there.
One thing is for sure, wiring looms are a dreadful source of trouble, always have and most likely will stay that way. But I kniw about wiring and I know next to nothing about can bus or usb. Jumping into the dark is not my thing.

I didn't switch until I broke a wire in the chain.

It is where I am at right now, on day 5 of having my printer up and running. Before me, my brother helped my dad with the A and B motors which had a wire break in it too. My original builder did not wire it very neatly and with the standard pvc wires. Not ideal for cable chains and moving parts. I ordered silicon wires with the view to do all the critical stuff again myself, but maybe going usb or can is the way to go in my situation. Not decided yet. First will fix my heater problem, which is easy as the break is glaringly obvious (I think), but in the future I must do something to address the mess I am left with.

I have to turn the telegram bot service off to keep my communication timing good, but other than that, I'm loving NiteHawk-SB over USB.
As far as the timing goes, I'm probably going to switch from an RPi to an intel based mircro pc

Well I'm thinking a bit different about Canbus. I recently builded a Voron 2.4 R2 Pro and it wasn´t easy finding out all the stuff. Flashing Canbus and making it communicate isn´t that easy but now that it works I would say go for it. if you have some experience and patience. You are going to love it to my opinion. It took me about two months and there is a lot on Youtube to make it work. Voron is awesome.

I recently found myself asking the same question about what cable to use for can bus so, much to my wife's disapproval I went and cut the ends off of any cable I could find that may have four wires two of which are twisted pair and shielded and a vcc/ground of sufficient gauge to carry the 5 amps as per BTT documentation, plus a safety margin for my own sanity and I am please to report success. The cable I found was a USB A to USB B cable the kind that is commonly used for printers.... err I mean the other kind of printer you know like the kind you would find in an office, anyways not all of those cables are the same I cut two open before I finally found this one but it is easy to tell the difference slightly thicker higher quality insulation and the gold plated terminations were the dead giveaway. the power wires were 1.3mm or awg 16 had at least 10 strands . according to https://www.engineeringtoolbox.com/wire-gauges-d_419.html it should be good for max 7 amps. the cable is flexible but after stripping mor of the outer insulator off than needed aand folding back the outer layer of shielding soldering the earth wire to the shielding and then heat shrink the two or so inches at the tool head I found that to be sufficient strain relief once firmly zip tied to the 3d printed bracket I found on printables or similar.
I hope this helps someone as I have been helped from other members
happy printing
