Schaublin 125-CNC retrofit.

that's a nifty little program, I'm curious to see how accurately it can control the variator.

I'd think the contactors would be kinda difficult to switch accurately for short durations.

Mark, put some flyback diodes in the contactor dc coil circuit, i was thinking this might be flyback voltage

Thanks, me too.
I just realized it needs an enable pin becasue from the original video, it is not allowed to move without the spindle turning. Something like:

Would flyback voltage still spike and cause issues if the contactors are manually activated (i.e. screwdriver)?  I'm genuinely curious.

So am i.

No eBay APP ID and/or Cert ID defined in Kunena configurationSomething like this should solve noise problems.

Given that there is no energy stored in the inductor (ie no collapsing magnetic field) I don't see where that voltage would come from.
