Connected an Raspberry Pi 4 to the printer to run OctoPrint. This was working 6 months ago just fine. Anyways, for whatever reason it killed the USB on the Pi 4 and fried the main board on the SV04. What recommendations might the community have?
- How did you narrow down the problem to the mainboard? Could be there any other reasons like the weak & cheap power supply unit. Maybe disconnecting all connectors except the display port from the mainboard and connecting it via USB to your PC could help to clarify.
- If there is still warranty on your SV04 asking for a replacement shouldn’t hurt.
I saw the sparks and smoke come from next to the USB port on the main board as I happened to have it flipped on its side. Everything was stock power supplies so it shouldn’t.
What a pity - it seems you’ll need a spare board from Sovol or a second hand SV04. If you are capable in repairing that SMD PCB you might find helpful information here.
hey thanks, this looks really helpful. The damage I saw was between the micro USB header and the CH340G.
