Lost them while busy trying to find a short on the board, 3 Ferrites were blown and the FET is shorted !!! Waiting for replacement FET's now.

Thanks J4bberwock

anything else than the ferrites and fet blown?

it can be helpful for some other people.

As far as I can see, nothing else damaged, I did get a confirmation from gridseed that you can use 100ohm 1206 100Mhz Ferrite Bead instead of the 300ohm 1206 100Mhz bye the power plug, but they say you can't go lower than that, but I suppose if your using a good quality power supply you can just put a 0ohm resistor in the or jumper it like you guys do.

As for the FETs, I have ordered :

CSD16321Q5C (replaces IRFH5302) * Dual Cool
CSD17556Q5B (replaces IRFH5300) * Correction these are not DualCool

Which are the DualCool type, should run a lot cooler Grin

Sorry guys, just made a correction on the above post, the CSD17556 is not DualCool.

Got the CSD16321Q5C on 1 blade so far, much cooler, finger does not burn now when I touch it Cheesy

Will Change the CSD17556Q5B's this week and then to do the resistor mod.

If I increase the resistor by say 3K, what will the heat be like on the gc3355's are heatsinks needed ?

Wish I had my cnc milling machine up an running, would have converted the whole blade to water cooling.
