Hi Ian,
MK4 will run off the same control box so there won't be any updates in that log.
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
