This is where I'm at., at the moment.
I'm powering the masso, the machdrives servo drives, and the encoders all from the same source, which is a device on the gerber power supply, its spits out 5V and 15V.
I have created a shared ground for the 5V encoders/servo drives near to the masso -ve
Images, lots of them, sorry
This diagram can be blown up, its' the finished wiring configuration.
This is the Gerber power supply
This device below puts out +5v and +15v.
I was going to use the 5V for the encoders & machdrives, and the 15V for the masso
here is the terminal block with capacitors across the +5v and -5v signals, with a heavier wire running from the masso -ve to the -5v terminal.
This is my control ground.... I hope I've done this right.
