Building My First CNC Router, Looking for Advice & Other Info

[AlexDoran]

So electronics wise, i have:

4nm Nema 23's
Leadshine AM882 Drivers
DDCSV1.1 Controller
2 x 600Watt 68v PSU's
1 x 23Watt 24v PSU (for the DDCSV1.1)
2.2kw Water Cooled Spindle & Huanyang VFD
Will be using Mechanical Endstops / Microswitches

Had forum member Leadhead pop down today which was great, he had some great tips and recommendations on the build, especially the Nema mounts he suggested which will drastically improve how well they perform (no twisting when stepping).

Got some more bits to sort out but carrying on dry assembling and finding tweaks.

Also gearing up to get this done with the controller:

Made some progress on the electronics enclosure over the weekend, few people have already mentioned about cooling and moving the VFD out, i got some methods to try and reduce EFI and there will be ~4 fans in the case for cooling.





Starting to think about my wiring in general, how would it be best to run my Nema23's in Bipolar Parallel or Series? Considering i have 68v PSU's? Also, can anyone point me in the right direction of the name of the 8 pin twist a lock connectors i see commonly used?

Thanks

Nice! Very neat there, I'm going to use a mini tower case for my PSU, steppers drivers & breakout board.

I'm mounting the VFD directly onto the T slot aluminium frame.

Bipolar Parallel is the way.

Bipolar Parallel is the way.

That's actually how I like my women ;)

What about the 68V ?

[Nickhofen]

Motors has 8 or 4 cables, I miss that.

[AlexDoran]

The motors have 8 cables, is there a way to wire in parallel whilst only trailing 4 core wire back to the driver??

Thanks

Alex

Yes, that's how it's usually done. Bring the 8 wires into some kind of junction box with a four-core cable coming out and going to the control box. You can hard-wire the four-core into the control box or use an appropriate plug and socket. I use XLR latching connectors but there are others. My "junction boxes" are 3D-printed (cheaper than small plastic boxes from Maplin) with choc block inside but as long as the cables are securely joined and protected, use what suits you.

Mine never came with a manual but I bought 2nd hand AM882's.
