I’ve had my SV06 for about a month. Out of the box, I followed the setup steps:
Auto Z-align
Auto home
Z-offset using the paper test
It printed well at first. I noticed some geometry issues (squares weren’t square), so I adjusted the Z steps. Then I noticed the walls were over-extruded, so I calibrated the flow rate. That’s when prints started failing.
Over time, it got worse:
First layers started having gaps
The nozzle started crashing into the bed, especially toward the edges
It began colliding with prints and knocking them loose
Adjusting Z-offset made things even more inconsistent
Eventually, I reset the EEPROM and started over. I re-did the whole setup process — same steps I did originally — but now I can’t get a reliable print at all. It’s like the auto bed leveling system just… isn’t working correctly anymore.
I read that a firmware update addresses a similar issue — but I already have firmware 2.0.0A, which came installed from the factory. So that shouldn’t be the problem, right?
Also, this might be anecdotal, but when it does auto bed leveling, it doesn’t look like the nozzle even gets close to the bed — it’s hard to tell how it’s detecting anything. I’m new to 3D printing, so maybe I’m misunderstanding how it’s supposed to behave, but something feels off.
Has anyone else experienced this kind of slow breakdown — where the printer worked fine, then calibration made things worse, and now it just can’t print reliably?
