3 Axis CNC router

Glad it helped - I was pretty scared of this part of the build!! Clive and Dean were super helpful as usual. I think I used 2.5mm tri-rated, I'll try and remember to check for you when I get home.

In fact you can see in the pictures it says 13AWG which is 2.5mm. It hasn't seen any hard use yet so remains to be seen if it will work well, but it switches on without killing me or catching fire, so that's a start!

It was Clive that put me on to you and convinced me I could build the supply. It looks really simple but at the same time I can totally understand the fear lol I was petrified but now I think it'll be relatviely easy just trying to work out if I can cram this into an ATX power supply casing if I move the fan externally and add a 2nd fan either so it blows in one side and sucks out the other.

I want to try and fit the stepper drivers and self build PSU in a PC mini tower case with a whole pc as well.

I have a mini 80plus PC power supply I can fit somewhere in the case (It's about 1/3 size of ATX) and I think I can put the AM882 where the drive bays are. I could ditch the Hard disk and run from a fast USB flash drive or SD card it will be quick enough for linuxcnc. Or I could mount the hard disk somewhere else. I think as long as the PSU's extract their heat to the air and I add a bathroom extractor fan as well for the pc and stepper driver waste heat I'll be ok. Maybe add an active intake as well sucking air a distance away from the extraction point.

Joe A picture paints a thousand words I tend to point people to your P/S vids (if that is ok) as they are an excellent way to show how easy they are to build. There is one point and you have it correct is that you must not but an earth (ground) to the bolt on the top of the transformer that runs through it. It is ok at the bottom end ie the plate.

If you do die can you get some one to send me a PM saying get 4mm wire lol ;) I missed that but actually managed to read the part number off the connector blocks and find them on ebay lol.

No worries Clive - just glad they are of some use to people!
Btw I have made a playlist of the two videos here to keep them together: https://www.youtube.com/playlist?lis...zD30sZjtp_VyqY

Those connector blocks are pretty huge and a total overkill! I recon 2.5mm should be ok as it is rated for 30amps
