just found the motor at arc euro, its a dc motor, so I have to agree, he has fried it, by reading, like me, the main sticker, now its been pointed out, its clearly for the mill, not motor, so original fault lies with board, or pot, and I bet its the flippin £5 pot!
So its back to him later, and arguing the point, I hate this confrontation, I'm an honest easy going guy and expect same back, hopefully he will realise his error when he tests output of controller and does the right thing by me, hmmm, not holding my breath!
I have identified the board from serial numbers on the pics shown on arc euro site, looks like NOBODY else sells these motors or controllers, Hopefully John can save the board!
