@fcwilt Yeah - wiring is my biggest struggle, its why the toolchanger will be another couple months as i figure out how to keep them all arranged.
I wasn't talking about the printer at all - rather the very happy bearded dude crouching inside the printer - an odd place to find a very happy bearded dude don't you think?
What if the customer doesn't want to purchase a printer complete with a very happy bearded dude?

@fcwilt and barefoot at that!

The hobbit pictured is very happy to live inside the printer where he was made!
The XY (for the gantry itself) should be solved with Seperate-but-connected cable chains along the X and Y axis, but every solution I've tried with a "supported loop" similar to the E3d/Jubilee cable chain has been as kudgy as shown, particularily for the 1meter+ cables I currently use. for anything over 500+mm in a single direction, I'll probably have to make it so that only CAN devices can be used to reduce wire mass and complexity, so i can still use a zip tie or ruler. I have the 1LC's ready on Hemeras, and am excited to give them a shot as time allows

Perhaps shoes are an extra cost option?

To be honest I never looked at the printer - I was taken aback by the very happy bearded dude - who, as mentioned, is barefoot.
Perhaps you would engender greater confidence in your company with a more "serious" presentation.
I will now look at the printer.

OK I have now looked at the actual printer.
I see what you mean about the wiring.
What is all that wiring that is "looping up"? The wiring to the bed and to the extruder will need something to allow motion but nothing else - correct?
On my printers I use a remote drive extruder (a Nimble) and the drive cable provides the place to secure the extruder wiring. That's one of the things I like about the Nimble.

That's much better - you look friendly without looking somewhat, shall we say, over stimulated.

Its a toolchanger - Each Individual tool has its own wire bundle that goes back to the controller, meaning that there are quite a few loops along the back, in addition to the 9 (X-stop + Toolchanger stepper + Optical sensor) wires that are always on the gantry for the toolchanger head. All of these need to move, but the tool-specific wires need to be tucked away outside of other tools when parked.
Bed has 6 wires run to it, as well as another 5 Wires run for my Machine Vision camera+servo setup for tool offset calibration. Those also need to move, but are much more consistent and will have their own cable chains. A SSR controls flow to the AC bed.
On the bottom, I'm trying out a 24V ATX PSU - I wanted something that could easily be toggled on/off, as well as breaking out 24V and 5V for the Raspberry PI and the like. This will not be used as seperate 24v + 5v PSU's are much cleaner and simpler to support.

Interesting.
But I thought printers with tool changers had all the wiring running to a moving part (on the X gantry) and the different tools "plugged in" to the moving part and thus all tools shared the one set of wires.

Sadly there is a patent on that.

My TC design can use either of these two coupling systems (I started designing the Stablebot Core after e3d's reveal of the TC system)
https://e3d-online.com/products/toolchanger-motion-system-bundle-tools https://jubilee3d.com/index.php?title=Main_PageAside from patent issues - This makes it easier to support tools like the ASMBL, Cameras, Insert Placers, and many more tools that haven't even been created yet (I have a pellet extruder on the way!). But, it adds bulk from unique wiring per-tool. Perhaps V2 will include reliable on-gantry wire harnessing if there is a possibility of not infringing on other patents

Really? A patent on something so obvious?
Who holds the patent?
What country issued the patent? I know America is terrible about issuing patents without taking to time to research the existing technologies that may apply. You might say we issue the best patents money can buy.
Thanks.

That picture does not exactly fill me with a feeling of confidence.

Yes that looks like one of those patents issued by our patent office by someone who failed to do the research to see that this is an obvious thing to do and thus not deserving of a patent.

@fcwilt Oh, plenty of that, but I don't have the $ to play anti-patent troll.
Maybe someday.
sorry @bricoletout for occupying your thread.

Yes I will, but it's a hard work to choose.
