Ok, hopefully you can get things sorted between you if he does still have them.

forbes is a good guy, he's posting me out the missing parts

Yes he is, just his memory isnt great, suppose that is because he is very old

I made some progress last night. I removed the old kit from 1984


And went all 21st century with a touch screen


The pc I'm using only has a single DIMM slot, but I managed to find a single 1gb DIMM which worked

I installed mach3


I was just about to power up my lP-A controller, but noticed the power supply I purchased was AC and not DC I'll have to wait a few more days before configuring mach3.

I've still got to refit my servos and for the VFD, so plenty to get on with.

Coming along fine, lucky you didnt power the CSMIO, not sure how it would have reacted but wouldnt think it would have been good.

yes indeed, I check the invoice, I did order a dc supply, but the lack of + or - on the terminals gave it away.

Can anyone help with the pin outs on my muirhead vactric optical encoders??

I would look up the pinout for the 7406N chip and see which is the VCC and Gnd, you then can trace the wires to see what they are. After that I would imagine you should be able to see which is  which regarding the A and B channel. I am sure I scoped this encoder for Forbes, so he may still have the info I gave him. Doesnt look like there is an Index on that encoder, it may be there just not wired up but really a scope would be the only way to test if that is the case.

Thanks Hood, forbes is looking around to see if he has a drawing still for this encoder, as I received two slightly different types from him. If not I'll have to see if anyone local has a scope I can borrow. My DVM shows freqency output, so I may be able to see something??

I tried to fit the servo motors last night, but first found that the PCD on the mounting flange was different, so I had to strip the end plate from my old motors onto the new motors. This went smoothly enough. I then tried to fit my pulley to the motors and found that the dia of the spindle on the new motor was slightly larger. I don't have a boring bar small enough to enlarge this on the lathe, so I've ordered a reamer to get the job done.

Had a few hours of pulling my hair out last night, didn't think this would be a smooth conversion. I'm sure all the effort will be worth it in the end.

Sadly forbes was unable to help with the diagram for one of my encoders (photo above). I have worked out 5v and ground. Bit nothing else. I've noticed that the encoder or have 6 wires, while the others have 8. Is this going to be an issue?
