Warped Bed Question

Hello everyone,

I just received the SV06 ACE, which is my 2nd printer after an A1 mini. So far everything looks great and I was able to quickly print objects. However, when printing a large PLA first-layer sheet I noticed that some regions close to the corners were not as good. The problem persisted even when manually increased the First Layer Height to 0.3mm. I’ve ran the Heightmap Calibration function using Orcaslicer to get the bed mesh and I noticed that the corners of the bed are highly warped (see image below). I know that ABL is supposed to correct for that but a 0.8 mm min-max range seemed a bit large, especially for printing larger objects. My question is the following: Is there a simple way to manually adjust the bed to mitigate this warping effect? Do loosening/tightening the screws underneath the plate help?

Thanks in advance!

Haven’t you forgotten the famous foam block between the bed and the rails when you flip the printer?

That was my first thought too after watching so many people on youtube forgetting to pull that one out. Unfortunately, that was not the case here…

Are you sure?
I also thought I had removed it, but I was wrong.
If you don’t flip the printer by putting your hand under the bed, you can’t see it.

Yeah, I just flipped the printer and rechecked just to be sure. No foam left. I remember removing two small blocks yesterday that were very well hidden indeed.

I’ll just say that mine doesn’t look that much different…and I haven’t seen a flat one posted anywhere as of yet.

Sorry, I was in the dentist’seat.
But anyway, I just agree with @Lion , my mesh isn’t so different.

Thank you, both. It’s good to know that my case is not unique.

I was wondering if installing silicone bed spacers (Silicone Bed Spacer Modification - SV06 Knowledge Base) could help. Has anyone tried this approach on SV06 ACE? Without removing the heat bed, the original spacers look like they’re molded to and one-piece with the x-shaped bed holder underneath, but I may be wrong.

Maybe you can try printing in standard mode and, if you’re not satisfied, apply mods.

I glued hole reinforcement rings made of paper to the lower parts under the screw connection of the print bed and compensated for the uneven height.

@mich0111 Honestly, it doesn’t seem to matter when I print multiple small objects, but for large ones I can see the difference.

@Oliver Thanks, this sounds like a good idea. Does it completely eliminate the deviations? Could you perhaps share a picture of how the screw connection looks from the side?

Not sure it’s a good idea when you heat your bed to 100°C

I have reduced the deviation to about 0.3mm. 100% will be difficult. Unfortunately I can’t send a picture. I don’t have the printer anymore. But don’t worry! The next printer from Sovol is already on its way to me. :wink:
