Help for MOTOR 2.2 Kw and control board optimum BF46 milling machine

[BILLYBOUM]

Hi Irvine,

The idea was to keep things cheap and practical considering the price of that board is around 1.000 euro - so even if i could replace all components, it should be cheaper than buying a new one at manufacturer.

From the start, I came to a specialist in electronics and TV boards : he said he was not able to repair my board ( despite all his oscilloscopes and stuff in his workshop ... ) so apparently, this kind of problem is not so easy to solve even for professionals.

I understand and thank you for your technical comment :

Your only option is to replace them all with known good NEW ones, you cannot assume the ones in the other board are good. Even then there may be some other failed component which will cause one or more of the new MOSFETs to fail, e.g. a dodgy high-side driver, leaving you back at square 1. You need more knowledge and more equipment than a multimeter to fault find this board.

I will try to see if i can find second hand board plus motor from people transforming this kind of mill into a hi-speed CNC, and in the meantime, i'll continue to investigate what is wrong on my board.
