    My chinese milling machine with a brushless burnt pcb, due to really bad heatsinking and designing, no fan and enclosed in a box ....

    I asked many and many questions for this power supply, now it works fine...

    So I send schematics made with Kicad - free EDA soft - and also files with doc extension.

    Far away from my workshop, so couldn't give some pics .... Next time.

    Hope this helps.

    Sadly I think i'm not in this case, with this kind of "milling" so u can use it, to diy in your workshop...

    Next step, secondary pcb to drive the brushless, a draft is joined.

    Surely mistakes in it, so check it carefully.

    By example, L1 to L3 are - to check also - Burklin items CHI 211B 4,5/1x0,6

    Gee, I vaguely remember this project; it was a while ago.
    I am glad that you were successful in completing it, and thanks for sharing.

    Is there someone who is fluent in both English and French that could help to make a better translation from jm-a's original text, were they to send it to you? Translation programs are better than not being able to communicate, but still leave much to be desired.

    Hi Sgt,

    Just added other stuff for this post.

    I'm going to redraw original schematic with english captions.....

    Maybe it will be a better result ????

    Translation trial, someone in the field will of course, perform a much better work!!!!!!

    Thanks again for your help. Great forum.
