Hey,
I recently purchased used MAHO (I believe) 300 - unfortunately without the original BBC LE 10 b-E feed motor controller and only simple PWM DC driver, without any tacho feedback.
I am hoping to re-do this system to actually take the tacho into account, but first I'd like to understand how it was working in first place.
Thous, I've got couple of questions:
Does anyone have access to electrical schematics? I am especially interested in anything regarding the original motor controller, where it was powered from.
Additionally, what will be probably the most useful - is there anyone with similar machine and is able to measure the DC voltage that the motor is being fed with when running rapids especially when rising the table? I am curious what's the actual voltage supplied when under load.
Machine photos for reference:

Thanks!
