A few weeks ago my Z axis stopped moving, the brake was no longer being released. After probing wires I determined that the windings inside the brake had failed as it was an open circuit.

Sorry I...

Life got in the way and this project and it sat for a while, I've slowly made progress while picking up parts I needed when I found them for a good price.

I pulled the servo power wires and a cap...

I doubt I'll be using the CSM spindle and drive as I don't think they can be run on single phase.

In my opinion, one of the greatest sellers of these old machines are that they can run on single...

Ron, Thanks that makes a lot more sense now on the SBD, most SBC's have a CF for a hard drive on the board.

I'm starting to think the spare cabinet was off a larger machine. So the CSM spindle could be an option but it seems it could come witch future cost? I don't see any machines past the P1 with this...

I finally got the CF adapter to boot. Somehow I managed to screw up the original hard drive so it forced me to take a different route. I put the CF card in and booted from the DOS 6.22 disk, once I...

Ahh. That’s what all those contractors in the side box are for. Seems like a mess. What’s the point of shifting gears? More torque at lower RPM? Higher speed?

What’s the CSM spindle? Is it better or worse than the one I have now, if it wasn’t broken?

All the cables to the spare box were cut just outside the box. The wiring seems similar but it’s a -B control and I currently have a -C so it would be stepping backwards slightly. Also I don’t know...

I’d rather not dump the Milltronics controls. I already have a running Cent 1 machine and I do a lot of my programs in the conversational on the machine. It’s really great for one offs and quick...

Yes, I don't have 3 phase so a newer single phase VFD would be best. I'd like to retain the rigid tapping, I've read that some VFD don't support what is needed to do that.

Any recommendations on a...

I’ve read on other threads of people having similar meltdowns from the VFD. I guess when it fails it throws straight line voltage to the braking resistor. This makes me wonder if a slow burn fuse on...

Yes. I just need to source the 11 pin connector.

It melted the wiring to all 3 boards where they come down from the cap. So, I’ll need to recreate the whole thing or start cannibalizing the other cabinet.

Here is a closeup of the carnage.

I took a gamble and bought a P1 that appears to have suffered a Saftronics VFD failure that resulted in melting one of the Glentek GA370-3 boards via the braking resistor. This seems like a common...
