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?
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.
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.
@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?
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.
Custom-made is certainly an option. But I don’t have any manufacturing options available. In my case, the front part of the print bed was just a bit too deep and I didn’t want to dismantle the print bed again. The reinforcement rings are about 0.1mm thick, but they contract a bit when screwed together. I was happy with the 0.3mm difference for now. But I could have improved it a bit. The rings can still withstand the max. 100°C of the print bed. Since the print beds no longer have adjusting nuts, I have already compensated for it in this way on various printers. This does not make the unevenness in the print bed go away. This can be improved with Cabton tape under the sheet metal.
Finally, I computed the heightmap 4-5 times, each time tightening or loosening 1-2 screws. The result is shown below. I went from a 0.8 mm min-max range to less 0.1 mm and the whole process took less than half an hour.
How have your bed spacers been holding up after about a month? My printer’s bed isn’t as warped out of the box as yours was, but it’d be nice to get it flatter, so if the spacers are reasonably stable over time, I might pick up some silicone tubing…
