That was some time ago / first one I'd done except my own, sorry! Connected the output wires to the mains and the spindle to the input, it switched on as normal (as the protection diodes on the IGBTs will have rectified the mains to power it) and let me put all the settings in. When I pressed run it went bang and lots of smoke... got it to work again after replacing the IGBTs, but something else died after about 30 seconds and I couldn't work out what it was.
