3 months ago You were ment to cut the traces but fysetc seemed to have screwed up the trace design. (see #9) Traces don't go through the top layer. so its impossible to disconnect 24V.
I'm attempting to switch a fan on the fystec sb toolhead to 5v via JP1 or JP2, but I can't determine what I need to solder or cut.
I see three pads in the jumper, and none of them appear connected. I measured impedance in the pads, and soldered the one with no high impedance to 5v to the center pad, and used a knife to try and cut away the other pad, but only succeeded in bridging the 5 and 24 volt rails.
What needs to be done to use successfully reconfigure the fan to 5v?
