I do have a manual with some data in it. All the parts seem to relate to Sei parts numbers rather than what sort of drivers screws etc. I think the motors are steppers with encoders fitted and it's fitted with a 3 phase industrial spindle.
It does say in the manual that data is transmitted in ASCII if that means any thing to you. To be honest I won't have a clue how to change the operating software or change the code.
I had hoped that I would be able to muddle may way through learning from my mistakes but I don't seem to be able to get to the stage where I can make mistakes.

Thanks, for your interest,
Paul
