Good job Brian! You definitely took your time and put some thought into this. That’s a great looking panel! I really like the printed din rail adapters for the drivers and boards. Can’t wait to see what you do with this machine!

@ 7:01 the VFD extension cable uses IDC connectors, instead of filling/cutting the key of the connector, you can simply unclip the cable hold down bridge then peel back the cable of the pins. Cut the original pin perforations of with a sharp blade or shears, then reposition the connector pins over the ribbon cable correctly and hold down with the cable bridge. Place the IDC connector in a vice and squeeze the connector forcing the pins to punch the cable and secure the bridge connectors. hope that helps.

Great job explaining how everything is wired and why you did things the way you did. Very neat wiring as well. You've got a ton of components in that case and it's all logically laid out.

Looks fantastic! Very clean with the wire duct, reminds me of the inside of an elevator controller. I did something similar using a steel backing plate to lay out everything, doubled as a ground plane and additional heatsink for the drivers with the added advantage of being able to run the grounds for all the shields short as possible behind the plate without looking too messy.

Thats looking good man, thanks for the amazon list. Very handy, I will source some materials from there!

Looks fantastic. You are fast!

Nice and clean 👍🏻

Looks good my friend. I just finished my X Gantry tonight, need to get going on the Z-Axis.

That Amazon list is great. Thanks man. I'll buy from your affiliate links when I get around to it.

looks really neat. just a thought, it may be worth putting in some filter foam in front of the fans as the enclosure is likely to be next to dust and grit from the machine.

Awesome!

Very nice panel. The only change I would suggest is that the green button light be wired to a normally open contact on the contactor so it only lights when the contactor is in. The red button light should be wired to a normally closed contact on the contactor so it lights when there is power to the panel but the contactor isn't in.

Hello Brian, I discovered your channel today and I subscribed immediately, I feel very represented by your way of being and the things you are doing, so thank you for supporting the diy cnc world by showing us your projects, I would like to know what experience you have had with with The spindle cable, if it goes well, I would appreciate it if you could tell me which cable it is exactly, it would be great, i'm building my cnc too, so that cable is something that has me somewhat worried, I do not want 220v 2.2kw risks bye !! 🙂

great work on the electronic and on the wiki ! try to use 12-36 v for the limit switch to avoid interference

Hey, very nice looking enclosure! I hope your VFD doesn't cause you EMI, I had to deal with that and it made me move mine out. If you want to quiet down your VFD fan (especially since your system seems completely silent otherwise!) it's a pretty easy task. Grab a thermal switch from amazon (I went with 40C) and wire it in line with one of the fan leads, then thermal epoxy to the massive heat sink in the VFD. You don't even need to open up the VFD at all to do it, the fan cover has a little clip for easy access!

I have the same VFD I added a 40c thermal switch to the fan curcit. I used a little thermal glue connect the switch to the heatsink located just under the fan. It works great, the fan only comes on when the spindle is under load, otherwise its nice and quite lol.

If you use one input for your limit switches you'll have issues auto squaring your Y axis wouldn't you? I'm not sure if people setup the PrintNC to autosquare Y like you would on a MPCNC.

Nice video Brian. I really like the idea of using a PC case for the electronics. I have a bunch of old cases that would be good for this. I haven't gotten the VFD yet so I don't think I'll need a large server case like you. I had a question about what current setting you have for the stepper motors? I've bought the AliExpress kit and it only comes with a single 350 W, 36 V power supply. If I'm calculating it right, that gives less than 2.5 amps for each motor which doesn't seem like enough.

Looks fantastic! Does the red button (Not estop) just turn off or how does it differ from estop the way you have it set up?

Amazing job with that case! Didnt you say in one of the previous videos that the usb was only there to provide 5v power? Its already done, so I wouldnt change anything regardless, but should have used another buck converter to keep another cable inside the case.

Useful video, thank you. Are you leaving the wires stranded into the various terminals or are you using crimped pins/ferrules? My understanding is that the stranded cables shouldn't be left bare as it can lead to poor connections or worse, fires due to overheating - I'm not an electrician though so I reserve the right to be wrong :P

Some of the components in your wish list or the wiring diagram on your website were not used in the controller. Any reason for this? Moreover, you have 2 EStop switches on the wiring diagram on your website but only one on the controller. Can you please explain the difference. Thanks

Hi. been following your vids now for some time and I'm also going to build the same machine, also with LinuxCNC on a Dell Optiplex with LPT. At the moment, I'm in the middle of purchasing the electronics. Some questions:.. 1) is the 24vdc psu only necessary for the spindle relay output and/or the non-contact type of limit switches you're using? Without any of these, the breakout board board itself will run off 5vdc USB alone ? 2) The 24vdc psu you have is 5a (120w). Is this much needed? Would 2a/3a etc be suitable too? (thinking about normal microswitch style limit switches) 3) Would it be necessary to connect the 24vdc GND and the 36vdc GND together ? (also thinking about 2x 36vdc psu - 1 each for 2 drivers/2motors) Thx. P

The discord link isn't working. Says invalid.

How did the VFD in the enclosure end up working out?

First of all that is a dam nice clean job on that box ..... But can i ask why you did not go with a usb controller ? and i dont think that the inverter should be in that box! it may have a problem with the drivers you know electromagnetic interference

Do you have a wiring diagram for the box somewhere?

Hi. Why you don't use usb board? I have problems with this. Spindle speed is incorrect with usb board.

Hey Brian, great work as always. Three questions: (1) One, can you share your 3D printed pass-through design for the USB and parallel connectors? I purchased the same ones from your affiliate link, so the printed design should work perfectly. (2) What's the purpose of passing through the USB? Doesn't the USB just go from the controller to the VFD? (3) Do you have a link for the long ribbon cable, or can you add it to your Amazon list?

Hi, Can I ask if I will use Stepper Motor Nema 23 -2.8A can i use DM556 ? there is not 2.8A in settings

Is VDF causing any issues being inside the enclosure?

FYI. I'm not seeing the VFD ribbon cable in your amazon wish list.

Hey Brian can you please show the wiring of inverter to 5 axis bob ?

Could have wired the two fans in series to avoid the step down, otherwise clean build :)

Not sure I agree with VFD inside enclosure. LOts of possible noise to mis steps. Just my opinion... very nice build otherwise!!!!

Why such difficult? Take arduino duo/leonardo and ad DM556N drivers. That's all. No need for com ports and other stuff.
