Hey, i recently updatet my RatRig V-Core 4 500 Idex to RatOs 2.1.
Now i have the problem that i can´t get my bed level.
Before every Heightmap i performe a Home and a Z-Tilt. The picture i post here is with the new mesuring points from Version 2.1 . The visible "wave" in the bed wasn´t as bad before the firmware update.
I hope you can help me, but i think i´ll need a new bed for my Printer.

This is when i change the z-tilt points back above the z-axis. its bad again and i can´t level it. in the version 2.0 the "wave" was way smaller and i got the bed in a span of 0.3mm.
Maybe this is helpful too

What sw are you running? 2.1 is not out yet, the latest is 2.1 RC4.
If the bed has a deviation of 0.6, you should be able to see it with a good straightedge. Do you have one available to test?
Instead of the bed being warped the issue could be in the y rails, but since patten seem rather similar along x, it would not be my first guess.
About changing the tilt measurement points: whatever points you choose to use, those points should turn out to be level in the map. With that in mind I cannot quite understand what points you used for the most slanted heightmap. Can you verify the exact locations?

Hey, sorry I totally mean the version 2.1 RC4.
I will look if I have something to look if the bed has this deviation.
I mean the points were the probe takes its measurements for the Z-Tilt.
With the 2.0.x is was front left, front right and back middle.
Now with the 2.1.0-RC4 it's: front left, middle right and back left.
Sorry for the unclear wording.

Hey, sorry I totally mean the version 2.1 RC4.
I will look if I have something...
what did the height map look like before the RC4 upgrade?

This is when i change the z-tilt points back above the z-axis. its bad again and...
like this but not so much range. the scale was about 0.3mm over the whole bed.

What I meant is that in your heightmap I do not see the three old points (left front, right front, back middle) being level. The z-tilt will level the points. Thus, I would like to know the exact coordinates you have used for the z-tilt. I’m trying to say that the map you are showing does not make sense to me, there is something wrong with it.
lament quartz
ah sorry for the missunderstanding, i will give you the coordinates on thurstday
lament quartz
Here are the coordinates the printer is using for the z-tilt and the corossponding heightmap
lament quartz
So i have compared the probe points with the height map.
Point 1 (front/left): x20/y10 z=-0.065
Point 2 (middle/right): x480/y230 z= 0.000
Point 3 (back/left): x20/y450 z= 0.000
So on the probe points the bet is theoretically "flat"
slow nymph
Yes, that makes sense. What does not make sense is the height map with the "old setup": It seems like the front left/right and middle are not flat in #1475787962322255922 message.
Have you been able to check the bed for flatness with a straight edge?
lament quartz
Yea, not with a straight Edge but with a straight piece of metal and you can clearly see the same wave on the bed as you can see in the map.
slow nymph
Ok, that would indicate that the issue is really in the bed. I believe you can still get reasonable prints, as the compensation mechanism should track the surface, but obviously the prints will have the waves as well. However, it is not very likely (read: impossible:) that the sw upgrade would have caused the bed to warp more. A somewhat more plausible explanation could be that heating has caused the internal stresses in the bed to release.
