Just watched your video: space is always an issue, not matter how big your shop is....
I have the same machine waiting for repair and retrofit, but I don't have the time now.I have planned to use the orginal toolpost and make the lathe as compact as possible, which means removing the cabinet on the end and a new mounting position for the Z-axis motor.
I will follow your proges with lots of intrest!
Thanks. There is a retrofit thread on the german CNCEcke.de Peters CNCECKE
Because the base has that large Pneumatics compartment behind the eletrical cabinet, he managed to shoe horn everything in there.
I don't really mind the Z axis over hang. I have a bench next to where the Schaublin will live, so that space is free.
Really cool to see these machines retrofitted with modern control. Especially like the way you made the Maho control work with no disturbance of the complex and good original electronics of the machine. Worked a little with the same Maho and always thought it was a wonderful machine - and an awesome machine with the controls updated.
Good to see it can be done!
Before I removed the original controller, I wanted to document what it did and how it did it. There is very little information online about such old CNC electonics.
This controller is powered by a pre-DOS generation Data General Nova 2/4.
Unfortunately, I have no troubleshooting information about the controller or the Nova. You would need additional test equipment to interface with the nova to interogate it.
I won't dump it, but will remove the Nova with it's Schaublin controller cards, and see that it gets to a museum or collector.
I doubt it. I cover that in this video. Without any way of communicating with the Mini Computor (it is pre-DOS) to interogate it, and without any schematics or information on the 13 Schaublin boards which integrate it, I do not have the skills to get that controller running. It is a Museum or collectors piece.
I know a workshop that bought such a machine new, they found out the controller was full of troubles . Like doing moves or toolchanges that were not programmed. That is why most of these machines have seen little use.
Thanks for that feedback. It doesn't really surprise me to hear that. There are a lot of huge very flexibly circuit boards and spade connectors. I imagine if the gremlins get in you will have a hard time getting them out. Do you have any idea what they paid for it?
