Hi,
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
Smoothing chokes 215124_65 C330

Thanks to : Sgt Wookie, Audioguru, CDDRIVE, Bill Marsden, 12, KMoffett.
Apologies if i forget others members.
