KX3 Spindle Problem

[Doddy]

See the link in post #21 - it's part-way down that page that describes the removal of the PSU. You sound like you know what you're talking about so you be able to eyeball the rectifier / smoothing / regulation in establishing a suitable transformer replacement.

Hi Folks
Final update on the goose chase. It wasn't the BOB, it wasn't the main motor board, nor was it the AP2 board. It was a circular magnet that had fell off the bottom end of the motor spindle which must send some signals via sensors back to the motor board. Discovered when I went to investigate the last area possible, the motor and the leads from the motor board. The magnet shaped like a polo mint was lying inside the plastic cover when removed. Machine is well enough dismantled now all I have to do is reassemble. Secured the magnet back on to it's register on the main shaft with some Superglue. Motor back into life. What a chase. For anyone experiencing the same problem I would recommend lifting the motor out and checking it would save alot of time and head scratching. Thanks all for the feedback and encouragement. Soon get swarf flying out the door!
