In post #95 in this thread showing the wiring diagram there were some changes made after that:
1. 68V linear supply was actually putting out 72V
2. 30V Switched mode power supply was removed (far right)
3. Z axis driver (MD542) bottom right replaced by another DQM860 driver, and powered by the 72V linear supply
4. 5A fuses going to each X driver replaced by a single 10A fuse shared to both (if fuse blows gantry stops)
5. 6A MCB type D uprated to 10A MCB type D to cope with linear power supply inrush current when switched on
6. 5V power supply cable from PC to BOB was replaced with a dedicated 5V DIN rail PSU (mains driven)
7. A green LED was included in the power on circuit when the main switch was switched on

Very happy with it and works well.

Thanks

Hi RouterCNC
I now have all my bits around me and startng to work through the wiring schematic;
Parts are;
2 off 36V - 400W PSU (for drivers)
1 off 24V 2.5A mini rail mount PSU
1 off 5V - 2A mini rail mount PSU
1 off CP0-10V BOB (cnc4you)
4 off CW5045 (cnc4you)
1 off UC300 (cnc4you)
2 off E-Stops (2 pos NC)
4 off 24V 10A DPDT rail mount relays
1 off 4A type D MCB rail mount
1 off 10A type D MCB rail mount
1 off Rotary panel disconnect
1 off 10A EMI filter (cnc4you)
1 off Green reset (NO) panel push button
2 off 24V fans (blown air into cabinet)
1 off Green panel mount led (5Vdc - live)
1 off Yellow panel mount led (24Vdc - live)
2 off White panel mount leds (36Vdc - live)

DIN rail mounting and red, black, yellow and fused connectors.

Oh and I have been given a PILZ PNOZ 16S safety unit, just not too sure how to incorporate this.

I did notice that you have an Allen Bradley unit, would this be of use to me or do I have enough above?
