ATX power on TEMP 2000

multimeter on ground and vssa is OL

ordering 507-1797-1-ND
-
hmm so maybe the power supply is ok. It must have been the hot-end hitting bed clip. I found other post saying the same thing.
-
It's also possible to convert the board to use a self-resetting PTC fuse, see https://duet3d.com/wiki/Connector_and_spare_part_numbers#VSSA_fuse.

Thank you, 507-1797-1-ND is a 0ZCJ0020FF2E, so that is the plan.

Ok I replaced the one for tr1 and tr9 tested and working. But i lost one of the pads when removing the tr5(the first one i did). The pad i lost was the pin2 or the source. Where can i connect it too. Please save me. Oh, i also removed the vssa fuse, my auto resetting one should arive tomorrow. It i put it where the original on was, can i stil connect the resistor on the back.

when lifting the old mosfet the pad came with
-
The source pins of the mosfets are all connected to ground. So you can connect the source pin of that mosfet to the source pin of one of the other MOSFETs. Or you may be able to connect it to the ground via that the pad was originally connected to.
The new VSSA fuse is larger than the old one so it doesn't fit in the same place.

Thank you for all the help. I appreciate the level of support you provide. I will do my best to contribute back to the form when I can.
