Game on!

Finally got the control box wired up late last night. It turned out to be much more of a PITA than anticipated, and wasn't helped by paying work/Christmas/New Year getting in the way. Anyway here it is:

Here's the little clipper/clamp thing I was talking about, seems to work OK on the bench, clips the charging waveform to the HT reservoir cap at 45.5V at high mains/off load conditions and clamps stepper back-EMF at 49V.:Whist making it I realised I could add a cap and make it do soft start as well.


If I find myself doing another machine, I'll likely do things a bit differently, having a small "sort out" box mounted on the machine to minimise the wiring, also I'll put the closed loop stepper drivers on the machine as well - that way the step/direction signals can be easily run on some small multi-twisted pair cable on e.g. M12 connectors.
