Did you ever get this sorted. I am in the same process of installing a SKR 1.1. The motors and endstops were OK to sort and put new connectors on but the head extruder board has me scratching my head. Plus I am unsure what wires go where from the filament detector. I will have a little break on here...

Many thanks William for your quick reply. I shall try as you suggested. It is most likely a blown board and there was a short in the heater cartridge on the hotend. This blew the power supply (some transistors and resistors were destroyed!). So it is likely that some damaged occurred on the motherbo...

I have the same problem!
The heated bed comes on when power is applied. Also when I turn on the nozzle via the screen, I can't then switch it off.
I am running firmware version 1.59

I bought an A30 that had a faulty 12v power supply. I installed a 24v supply and used buck converters for the fans and the mosfet. The firmware installed is v1.59, if I remember rightly. When I tried moving the z+ axis, via the GUI, the x+ axis moved. When I tried to move the x axis, the motor just ...

Thanks again _kaktus_ .

Try as I might I could not reveal a gap in the solder. So I bit the bullet and used a fine nail file to take off the remainder solder. I then found that the what I thought was supposed to be two solder pads turned out to be 1 big solder pad that joined two traces together. (Please see photo.). When ...

here is a photo of what the board looks like now. It is for 24v usage.
There are no pads under the number three, so I have assumed the pad nearest the number 3 is the correct one for the negative lead.

I am rewiring my heated bed to take 24v. I cannot seem to clean up position 1s solder pads. From diagrams I can see that the solder point 1 had two solder pads. Mine seem to be fused together. I have tried loads of liquid flux with solder wick, adding more solder and I just can't seem to part the pa...

Thanks _kaktus_! I look forward to seeing you continuing your WiFi project. I hope your current mod goes well.

Added another buck converter. The fan seems to be going just as fast. I have now ordered a new hopefully quieter fan.
