I have a wavy bed mesh on my V-Core 4 500. It's a fresh build and the mesh looks distorted. My linear rails aren't too tight, and I can't see any obviously bad pulleys. I rotated the flexplate, but the pattern stayed the same. The motor pulleys are properly secured with one screw on the flat part of the shaft. What could be causing this?

Since the waves do not follow the print sheet, the next potential candidate would be the magnetic material below the sheet: the magnetic field could leak through the sheet and cause a disturbance. Another alternative could be something in the y-rails, but it is not very likely to have this so evenly on both sides.
If you have a second build sheet, you could try putting it on top of the current one. If the waves dampen, it would suggest the magnetic leakage from the mat. If they stay as they are, it would indicate an issue with the y-rails.
following on what mazas said sounds like it could be the problem but I am wondering if its showing up that way as beacon is really close to the bed if you left out the UHF nut on the rapido hot end. I do not even know if it would home correctly without it in there but its something to check as that would allow beacon to get closer to the bed than it normally would.
First, thanks for helping me. I have a second new sheet on hand and will try it now.
@wraith reefThank you, I have installed the UHF nut as it’s in the guide, so this shouldn’t be the problem.
With the second sheet it looks much better. The big peaks are because the magnet is not strong enough anymore and there is a gap under the sheet at these points.
what would be the best way to fix it?
I believe there could be at least three options:
- change the magnetic mat into one that does not have that much varibility in the magnetic field
2)Change the build sheet to a thicker one that will dampen the leak
3)Use the compensation mesh in ratos to compensate this fluctuation.
I'd think option 3 would be the easiest. After all, the compensation mesh is actually built just for issues like this 🙂
@velvet shuttle Do you think it would make a difference if I used the magnet from the second flex plate? It is identical. I’m a bit concerned because I’m using the compensation mesh on my VC3.1, and in my case it doesn’t really work very well. If I could avoid relying on it, I would prefer that.
Could it also be possible that these waves affect my leveling, for example? Do many users have this problem with the magnetic field?
