DIY CNC 012 - Electrical Control Box
HTML-код
- Опубликовано: 16 июл 2024
- I've successfully designed and assembled the control unit, completing the wiring for both mains electrics and microelectronics. The CNC Router Electrical Control Box is now ready for testing. In sharing my project with you, I focused on optimizing the placement of components and wiring for efficiency. My main objective was to integrate a mini PC, like an Intel NUC, inside the enclosure. This allows me to run the Mach3 software through the Mach3 breakout board and remotely access it using software such as VNC server, eliminating the need for a keyboard, mouse, and screen to control the system. The setup includes 4 CL57T Closed Loop NEMA 23 drivers, a 36V 800W Power Supply, a 24V Power supply, an Intel NUC, Mach 3 Breakout board, VFD, mains fuses, switches, emergency stop, and all associated wiring with quick disconnect aviation connectors.

Your motor drivers appear to be daisy chained (red wire at the bottom of each one). Each red wire should be run to a terminal block instead. Also, the braided shielding of each cable in the enclosure should be soldered to a wire (ground drain) and all joined to a grounding bus bar. Corvetteguy50 covers this really well in several of his videos. You can also add noise supressor power EMI filters to power the VFD and the power supplies.
Happy New Year! if you are enjoying the series please give the video a thumbs up. Helps the channel out. Thank you :)
hi sir happy new year pls upload your free cad tutorials i just loved it and by your tutorials i created small parts and as a hobbyist i wanted to create big parts too
I no longer use FreeCAD unfortunately, I gave up with it due to many frustrations I had with its user interface. Still a great tool for basic CAD work, but as soon as things get complex it falls short in my opinion.
@@thehardwareguy any free alternative in your opinion ?
OnShape is fantastic
@@thehardwareguy thnks sir love from india ♥
two notes regarding your layout your VDF cable should be as far as possible from signal cables because noise can not be totally eliminated even with shielded cables. Maybe metal back panel would be better than wood to help reducing heat from the inverter.
Very informative. thanks
Very good job brother !
You mentioned difficulty in executing the 16 mm holes through the box sheet metal. I’d recommend using a multi / step drill, as they do a good job of making clean and accurate holes in sheet metal, and following up with the same from the breakout side will chamfer that side.
16 mm = .629”, 5/8” = .625”, which is a common step drill step size.
Of course! seems so obvious now you've said it. I have those in the workshop I just didn't think to use it. Probably could have done both the 16 and 20mm with the same bit. Thanks for the feedback 👍🏻
If the fans are insanely loud, you could try running them at 12 volts.
The other option is noise-cancelling headphones.
Thank you!! 🙏🙏🔥🔥🔥
hi sir can you provide connection diagrams
For NEMA 23 do I need a vfd ?
The VFD controls the Spindle Motor
Thank you for the info, excelent content btw
What size is that box?
16" x 8" x 20"
That is a work of art!! Thank you for sharing the whole process in detail. I am looking forward to seeing it all go and get calibrated. Puts my rat's nest to shame: ruclips.net/video/SJ8Mcgfx2aY/видео.htmlsi=cOppmopmCvgOQvRF
