Printer not follow bed mesh
Hi guy. My printer doesn’t follow the bed mesh at all.
What I have done is just do the print start normally. (Of course, I did the probe calibrate and have the perfect Z Offset with Paper test)
Then the automatic bed mesh. And Load Bed Mesh Profiles to ensure.
Still. It still print too close to bed
Anyone knows solution to this ?

I have exact same problem, someone please help ._.
Just to make sure: have you tuned the z-height in a live print?
Because it looks to close to the bed?
Paper method is only for roughly bringing it to the right height.
Afterwards, print a small rectangle with 300um height (or whatever you’re first layer height is). During the print, watch closely and use the web interface to tune the z height. Save afterwards.
If it’s still off, repeat until you’re satisfied
When you start a print, don’t interfere with the bed mesh by clicking load or anything (afterwards it’s fine).
Your bed is not really level either and needs mechanical fine-tuning, but you should be able to get acceptable first layer at least in the center region

I've had this problem too. The z height is calibrated properly in the center, but then is either too high or too low elsewhere in the bed, and the mesh shows exactly where. It seems like it just isn't using the mesh at all.
I think it fixed itself at some point after some unrelated config changes and an update but I don't know what caused it and it may be back
I have to look for @MarschallMarc Guide on the frame. That would help

It does work for me now, I just removed the bed mesh in the config. I think it had to do with it not redoing the mesh each time and instead using an older one. Removing that solved my problem
I have the same feeling. It was broken for awhile but not anymore. No one has admitted to there being a bug, but too many of us were having this issue and now it is gone. Interesting.
There will be bug for sure. As a tester I do find that the bed mesh doesn’t work at some point due to step/mms on the Z motors.
Something may overrides these numbers.
Hence, I’ll remove the frame and start recalibrate it first.
Hmm I still have this feeling. Is there a way to check that the Z is adjusting while printing first layer?

I think I have the same issue. What I noticed, first print after printer turned on - Z does not move at all, first layer is bad with all the waves, etc. Cancel print, send again - now Z rods move, first layer is better. But I have to check/test this more careful, not ready to accept it as a fact. But suspicious.
i have the same problem too!
Now i'm using Adaptive mesh bed leveling but the first layer in not good enough

thats pretty easy, you just take a look at the z axis motors when its travelling in x/y plane and you'll see if it moves 🙂
I will check it out tomorrow!
In my case i see the Z movements into the dashboard.
The software move the Z axis up and down but now i Will check the rodes and Z motors
im currently having the same problem, print failed because the nozzle started dragging on the bed despite having an active bed mesh

You have wrong Z offset, this is not related to mesh
