Another option for the desktop CNC machine that I purchased from Snapmaker works as well. The working space makes it easy to fit the whole chassis unit with the enclosed cover. It has two different laser modules that work perfectly for engraving. I have some pics shown while I was working on the GG upper and front panels. Milling the holes for tubes, Stax jack, and screws. I settled the speed to 100mm/min and 0.1mm step which gave me the balance of speed and a nice outcome. The bit is from Datron, 3mm Single Flute End Mill. I have another 2mm ball end bit from Snapmaker which I also used for milling the M2-size screw holes. The only complaint about it is the limited 200W CNC power which does not allow the drilling process. The 8nm laser module is the most satisfying. Easy to manage and nice outcome for the front and back panels engraving.

Another idea of mounting those heat generators using the JST jumpers.

I just completed it last week by setting it to ZF and 100ma bias ( +-20V rail). Still waiting the chassis and soft starter. Sounds better than my dynalo\hi with my HD800 and K1000.

Thx for the suggestion. Seems like I real need a softstart borad to built.

haha it seeems like a little bit overkill... i agreed but the price between 200VA/100VA is almost the same. same price more weight🤣

Thx Pars. Actually, i did`t ask the question clearly😑 My apologize. It`s the one in CFA Board near the VCC+- terminals.

Another CFA3 here to be built: The transformer i used is from Antek with 200VA 25V for each channel. Still waiting for the rectifier bridge.d which probably will arrived tmr. Hope i can power it up tmr ASAP, can`t wait to enjoy it. BTW, any help about the trimmer resistor near the VCC+- terminals. What`s it used for?
