Hello friends,
This printer is new, and I’ve printed about 100 hours with it. Today, I performed auto-leveling again, and the result was what you see in the picture—the last two rows of the build plate have issues. It keeps trying to level multiple times, but the nozzle tip never touches the bed. After several attempts, it says the process is complete, but the filament doesn’t stick at all in the last section.
I recorded a video, but it’s not very clear.
2mm out is quite a fair amount, did something get dropped on the bed? Which printer exactly? You might be able to fit some shimming spacers to level it out.

It’s almost like a small piece of plastic or something is stuck under the build plate making it uneven…

Check it is screwed down properly too.

My Ender 3 in 3 printer inithial has a 1.8mm drop at hot bed. First, I put the washers. And then, I realized its the table is flat relative to the frame, the skew is along the x-axis of the printhead. Then I removed the washers and aligned them from 1.8 mm to 0.4 mm due to the tension of the xz core belts on the printhead. but I had a smooth skew, In this case looks like something got caught between the PEI plate and the magnetic table, the hot bed is very much skewed in one place.

Hi guys.
I forgot to update this post — I got so distracted because this machine gave me so much trouble.
You see me with many problems in other topics:rofl:
I did a factory reset several times, downgraded and updated the firmware again.
During auto-leveling, it would run into issues at the last 7 points and get stuck in a loop, eventually showing the mesh build plate screen in the first post.
I disassembled the whole bed.
It didn’t seem like anything was wrong, so I put it back together. Then it occurred to me to apply a bit of pressure to the bed manually with hands😅from different directions.
Finally, I updated to version 23 again and managed to fix the issue. Now there’s still about a 0.4 difference in high spot, but I was able to level the bed completely by setting a +0.115 Z offset, and I’m getting a good first layer.
But another problem I’m having is that no matter what I do, the nozzle still hits the infill.
If you’ve noticed, in Creality Print version 5, the Z-hop value used to be set to 0.2 by default.
After the update, I saw that it changed to 0.4.
But it still hit infill
I’ve tested different patterns and even increased it to 0.6 — both normal and slope — but it didn’t make a difference.
Basically, the nozzle keeps hitting the infill.
Luckily, the parts I print are large with good surface area, otherwise all my prints would’ve failed:rofl:
the sound comes out of the room and it messes with my sleep at night.
All the problems in the world somehow coming together in my V3 Plus:face_holding_back_tears:
Better not be using grid, schoolboy error. Gyroid is better in that it doesn’t cross itself, but corexy machines don’t really like it, rectilinear is better than grid, try that.
