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

[Clive S]

i am still looking for the chap on the forum here who had made some plates for another build, still cant find it, if anyone could point me in the right direction that would be great.

Is this what you are looking for:- post 119

You could try posting a request for a quote here - RFQ. I know there are a few people here who have helped out others by making the aluminium plates for gantry sides & z-axis.

I will make a post, thank you.

That must be the one! Those plates look fantastic, i guess i will approach Chaz and see if he would be willing to give me a quote. Thanks for the link Clive.

Out of interest, i wondered if some of you more experienced members might have 5 minutes to spare, to take a quick look at my drawings and the the quote that was provided and see if you think it is reasonable?

Drawings & Quote

Thanks Again

What electronics have you decided on?

Also did you consider mounting the Hiwin's sideways on? I might be wrong but I went with sideways on because it simplified the build, the less complex your parts (And less part numbers) will reduce your cost but also less complex is easier to troubleshoot and fix potential problems.

My original design had a crazy amount of plates in it before I stopped to think about how to actually make it rather than what looked good in cad lol.

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 ;)
