It's begun....

[Washout]

Hi all,

As the first materials for my CNC Router have started arriving, here are the results so far:

The second pic shows the re-purposed 4U Server case housing the PS806-5 PSU and a 240v AC to 12V DC PSU for the fans (two 80mm fans will extract the hot air out the back). The 3 x PM752 drivers are int eh drive bay behind the blue 120mm fan in the lower left corner.

My wiring routing will be largely as shown:

Red= AC in to both PSU's - will probably wire both of of the same 3 pin input socket, which will be housed in a plate to be fixed to where the old expansion card slot are.
Orange = the route I will take for the driver power from and to the PS806
Yellow = the stepper wires and any other wiring e.g. limit switches, estop etc - I'll be using 4 pin XLR connectors
Green = earths from everthing back to the yellow star point and then back out the case via the three pin connector

The 12V DC motor wires will be roughly wher eyou can see them now running at the bottom of the case to the 2nd PSU.

The main power switch will be in line with AC live and will be a two button start/stop similar to what I have on the front of my pillar drill.

The breakout board will likely be mounted to the left of the PS806, with its feeds to the drivers going in the same side as the yellow stepper feeds.

Oh and there is also a pic of where I have got to with the mechanical end of things (ignore the undersized work surface - that is being replaced with something large enough and additional supports added). The thin bed ali profile was a fail purchase on my part and will be replaced with the 30mm profile you maybe able to see sitting on top of it and the thin profile is going to become wall mounting for my guitars and maybe tools etc, so it won't be wasted.

Got some more electrical stuff arriving soon to complete the enclosure and I have my ballscrews, bearings, supported rails etc, together with a 2.2kw watercooled spindle hopefully arriving from Chai soon.

3NM Nema 23's are off camera until I have worked through the rail and ballscrew mounting.

Cheers


Chris

PS. I am thinking that I should the VFD's earth back to the star point shown in the case in the pic and not back to its own 3 pin plug's earth (both will be on the same 32A spur, along with the PC that's going to run Mach3 so the whole rig is on its own RCD)?
