I have an sv08 and it got hurt by static electricity so I had to replace the toolhead. But since I replaced it, the printer has been unable to print acceptably. I talked to sovol and replaced all the wiring between the toolhead+motors and mainboard but the attached pictures shows how it prints now. it does a lot better than it did, but its current status is strange. How come half of it is smooth and half is crazy? It would make sense it just x or just y direction was messed up, but it’s half of both…
Static electricity doesn’t mess with wires, replacing the wiring seems to be an odd choice. It can and does mess with integrated circuits, so I would sooner be looking at mainboard replacement.
Still, this behavior seems almost mechanical in nature. Someone else already asked this, but knowing whether or not the same region of the printhead is consistently affected is going to be critical. You might do a few prints of a 5mm high square with an X through it, using the whole bed.
If it is consistent, I would be inclined to suspect a reassembly issue - maybe something loose at one end of the gantry?
Looks mechanical. Is it always that corner no matter the print? Check everything where the stress changes as the toolhead moves.
Your comment made me think it might be stripped teeth on belt(s) or gear(s)
From a 3d printing perspective, I have absolutely no idea.
But from the perspective of troubleshooting electronics, that’s a pretty awful situation: electrical shocks can cause all sorts of weird havoc with unpredictable behavior and unintuitive symptoms. If I was in your situation I would seriously consider cutting my losses short and replace ALL of the electronics and save myself from a major headache.
Source: I was tasked with fixing an MF/HF radio station that had been struck by lightning. And the ship it was on was only available around 0300 in the morning. I replaced so many components, including the ones that threw an error, but to no avail. I ended up replacing the entire station, antenna and tuner included.
