Validation of power supply

[Robin Hewitt]

I used to have a toroidal and home made stepper drivers right up to the moment when the mains voltage surge hit and all 3 axes suddenly failed the smoke test. It was like the bridge of the starship Enterprise when the Klingon disruptor hits the shields, I had a sudden urge to hurl myself from side to side :D

Jeeeez, I dread the thought, just embarking on my own home brew psu with retail drivers and opto board. I reckon my instinct would have been a head banging movement rather than a side to side.

Any suggestions to protect my earlobes :heehee:
