A Love Letter to Wiring | Finishing the Surface Grinder Control Panel

"I'll deal with it later." - SURPRISE! It's later! 😀

When I use ferrules on small wires I like to remove more insulation off of the wire so I can double over the wire before putting it in the ferrules . It makes a strong connections and I can use a slightly larger ferrule.

That notepad looks really cool. I'm on the verge of springing for one.

Nice. I'm used to doing this stuff for a living, in the LA area (HAC MTS3). I have always liked this stuff but there is no more work for it. Besides, at 70, I am long retired anyway. ;) Nice project. The software will be the fun stuff ;)

The quality of those prints and the etched(?) surface is insane, I constantly thought it was going to segue to a JLC ad for sls printing haha

[@keithmonarch447]

Good luck James.

I'm concerned about the e-stop being a NC to ground. If your conductor shorts to ground at any point, the control won't react. That's usually why you have it as an NC passing HIGH, so any disconnect, being via the switch or a break in the conductor, will force an e-stop condition.

100% correct, also a saftey relay monitoring the zones should close normally open auxiliary contacts for releasing the enable signal for the inverters. But at the end of the day it all comes down to how advanced does he need to make a custom machine, that doesn't have to comply with international saftey system standards since it's presumably none commercial, if he ends up selling this as a kit to customers it would be a different story of course.

I feel like I'm concerned about that connector on the estop. I'm sure it'll fail safe, but still a pain when it falls out and you need to re and re. Looks great

20:51 I would suggest replacing the RJ-45 patch cable with a slightly longer one, so it's about the same length as the other wires. Other than that, beautiful job!

[@timturner7609]

Gonna need some B roll with your design decisions for your board base plate. That looks clean. I'm kinda tired 9f my rats nest of wires going from my prototype pcbs to the uc dev board I use for development.

You could have just run a long wire from the desk to the control panel installed on the grinder to use to load and debug code. When you load software and hear loud banging, gear stripping, wining and metal tearing noises from the direction of the grinder, you know you have a bug! 😁 would have made debugging the software a lot more exciting!

kind of pushing the wattage on those 0805 resistors in total, since they are split up its not that big of a deal but I would keep an eye out on the 1.4k combination (yea I know you mentioned it but run of the mill no name 805's are only 0.1 watt and your at 0.1 watt with the math)

[@mfx1]

Careful with surface mount resistors they very susceptible to cracking due to mechanical stress I'd be quite nervous having them floating in mid air between switch terminals.

[@osgeld]

2:22 thank god I cant stand a box attached to a billion different things all hardwired without connectors, up till you said that I am rocking in my chair repeating "he cant be serious with that rats nest he cant be serious" (I have done oodles of industrial machine wiring) EDIT: my heartrate is down yes M12 connectors (cause they are 12mm screw threads) poke yoked with M/F, simple and cheap ... so cheap you can have 2 sets, one for the machine one for the debug station. Also unlike D-sub or Centronics you can mount them using a drilled hole

[@galbysvideos9867]

Nice job, not a criticism but with all of the connections and crimps are there voltage losses, but yeah great job and neat❤

[@TylerKrick]

Incredible surface finish, are you using fuzzy skin or what material is that? If fuzzy skin, mind sharing your distance and thickness?

[@BlakeGording]

nice

[@phrozenwun]

What happens if you loop back a single cable on the power side? If you have the extra pins, the hot should go no where in case of a loop back oops. Assuming the cables are M to F terminated.

[@the42year-oldhacker37]

Great video! BTW, what e-ink tablet are you using?

[@Vytor01]

James, what setup do you use to get those steady overhead shots?

[@FullSpeed_only]

Switching the RJ45 to a M8/M12 should be no Problem and you get rid of the annoying Plug.

[@osgeld]

yes industrial ethernet and serial runs on M12 and M8 but the RJ plugs actually put up with a lot of shit

[@belair_boy6035]

Where does the 24V line go if you connect the male to female connector on the micro-controller panel? If it can happen, it will happen. 🙄

[@Co4l]

Hi, will you make review for the new Qidi printer?

[@Kmnri]

It looks nice and i liked the video but ill be honest. This looks insanely overengineered.

[@cornoadmin]

Seems like you could have just shoved your mess of cables into a cable sheath?

[@osgeld]

just hides the problem, you need each "module" to be able to unplug from the machine for repair and debug (by module like this control panel vs hard wired to motors and power and blah blah blah just cause a switch got whacked and wont turn)
