It's often a good idea to include a reference of some kind to a standard on your drawings when ordering wire harnesses from a supplier, so you know that it adheres to a repeatable industry-standard, even if it is only to the standard of consumer electronics. Usually something like "Harness X shall adhere to IPC-WHMA-A-620D - Class 1" where 'Class 1' = General Electronic Products, 'Class 2' = Dedicated Service Electronic Products, and 'Class 3' = High Performance/Harsh Environment Electronic Products. Your harness supplier will know what that means, and if they don't then they might not be a very serious supplier. Might not seem super important, until one day you're unlucky with a supplier or a specific order from a supplier, and then it suddenly is super important :)

@ericlotze7724 2 месяца назад

Are there separate ANSI, or Preferably ISO Standards, or is IPC *the* standard when it comes to wire harnesses?

@stephen_hawes 2 месяца назад

ah, great note, i should have mentioned that! before sending to our vendor we actually drop the wireviz image into a FreeCAD drawing with some notes about standards, QC procedure, details on labeling, and anything else wireviz doesn't include

@ericlotze7724 2 месяца назад

@@stephen_hawes neat! A video on standards and how you set up things like that for vendors would be cool.

@Oysteims 2 месяца назад

@@ericlotze7724 Just FYI, I am not a harness design engineer - I have only done it sporadically. However, as far as I know, IPC provide *the* standards that addresses the _manufacturing_ of wiring harnesses (and circuitboards for that matter, that is what most of their standards relate to). There are a lot of domain-specific standards that mostly describe design requirements, or installation requirements, depending on the industry. They can be extremely useful for design engineers, but if you put them as a callout on your drawings the supplier will probably wonder how or why it relates to them. It is very common to reference IPC standards in the manufacturing data you send to wire-harness suppliers and/or circuitboard fabs.

Man, just hearing you talk about how much you love using git is great. It's an incredible tool that not nearly enough people use. Though I do think there should be an easier interface for non-technical users, because it's not just programmers who would benefit from git's capabilities.

@DarrenPoulson 2 месяца назад

I love your enthusiasm for all this (especially at 1.25 speed, which I've started watching youtube at!) :P I'm a devops guy, and definitely get a kick out of all the github actions that you're doing. Slowly dragging my work colleagues into it. Having everything automated is such a time saver, plus the audit path of the git logs makes it so useful. Most of my work is with terraform, but I've also some personal projects that I'm wanting to automate. Keep up the awesome work!

Quick question: Why are you not going for USB or CAN for the "Head"? In 3D-printing it became normal to have a toolhead board for all that... Z-probe, Nozzle cam, Y-probe, extruder, hotend...

@stephen_hawes 2 месяца назад

awesome question. i'm constantly reassessing the benefit of making the switch! it's NRE to do so, but ultimately it means a lighter head and drag chain. there are also implications about the upgrade path for existing users. this next release of the machine is mainly focused on DFM and a couple of other improvements i don't want to gate behind that bulk of work, but after that we'll be looking into a distributed controller approach as an option! it's really cool and i think the machine could benefit from it

Is there an equivalent cable manufacturer to like JLCPCB for pcb's?

@stephen_hawes 2 месяца назад

yes! we prefer using a vendor directly, but LCSC recently started a service, plus dirtypcbs.com has one that ive used before with great results: dirtypcbs.com/store/cables

@JimmyHacksThings 2 месяца назад

DirtyPCB is "decent", though they have a limited selection of connector types they support. I've just sent in my cable drawings to LCSC for some rather simple JST/Molex based cable designs, I'll set a reminder to report back here when they get in. All in all, the quote process was simple, though their online form for mapping cables to connectors is severely limited, so best to have a drawing and/or a photo of your cable as well!

@npriester 2 месяца назад

Just to add on here, I have used LCSC's cable service recently myself and it was awesome. Some simple harnessed with some JST connectors for AC power, plus I was able to specify some odd usage of a single crimp with two wires and they confirmed with their engineer it would work, tested it first, and reached out during each step. Highly recommend them!

@hed420 2 месяца назад

You should make a machine that can read the files and automatically measures and cuts wires. You can also have it strip the wire ends.

@i_might_be_lying 2 месяца назад

The thicker the harness that has to move, the more strain it would be under and will fail earlier. In this case, if you want an easier assembly, maybe think about splitting one huge harness into two, which will make it way more reliable. Of course, it also depends on cable quality and number of conductors per each wire (the more the better).

Early versions had that but were problematic. Even now with separate cables you have to be mindful and plug the cameras into separate root hubs on the PC.

@bouni8506 2 месяца назад

I think having the same wire color multiple times in the main cable isn't really cost efficent as the manufacturer needs to make a non standard cable for you in order to manufacture the harness ... Wouldn't it be more efficent to use a standard color coded cable (DIN47100/ IEC60757)? Sure the connectors would no longer have the same 4 colors but that woul make it even harder to confuse them. Just random thoughts, great video 🙂

@formatc1702 2 месяца назад

Hi, WireViz creator here 🙂 Currently, I've been using WireViz myself in a hacky way for system diagrams. Simply define each module as a "connector", and each port on the module as a "pin". Then you can route wires from pin to pin, each wire representing a cable. It's not ideal, but it works.

It would be even nicer if it exported something that contained text (like a svg or a pdf) instead of png, so that you can copy wire names and do ctrl-f to find a wire.

@NiklasAuBln 2 месяца назад

Wireviz usually export SVG and HTML (SVG + BOM), but due to the hacky connector Steven used to make the splices in the cable the export of SVG for those specific cables fail and only the png export succeed. -> for cables without a splice and just connector - cable - connector configurations SVG export works great

@ChefBenni 2 месяца назад

What you made / need is actually a quite old standard in the automotive industry, as your harness wants to be the same. So using standard and the way of makeing drawings would help with the right vendors etc. done that 20 years ago and a wooden board with nails is your best friend 😅
