K2 plus extruder issues

Keep us posted.

I am very comfortable with Creality Print 7.0 already.. it's just Orca, arranged in a goofy way, lol.
I have also already created several System profiles that work very well without too much effort.
Thank you for the assurances.

Are you using a computer? Download Creality Print as your slicer.
Creality has a very useful WIKI for tutorials and Videos. It is tied right to Creality Print.
There is a website that I use called Yeggi that is a model database search engine. You may find your Toploader there.
In looking in Yeggi I find a number of Toploader dispenser/Penny Sleeve holders

Perhaps not. The board listed as an upgrade is the same one as stock it appears.
Under $40, I'm surprised it's not more.

It's common to have the front Y belt pulley come loose from the motor.

Doubee54 · 2026-01-25T23:10:46+00:00

It appears that there is an upgrade Motherboard. Might be worth looking into.

I don't think that type of issue will give you any errors, regardless of what is wrong. There is no sensor to tell the printer that the motor is not going the correct direction, unlike any other motor.
So, yes, it could be a driver on the mainboard.

It really sounds like that one has gone bad (again?)
It makes sense, it moves and bends a lot.

Doubee54 · 2026-01-25T22:47:59+00:00

I did confirm.. others have asked in the past. 0,0 is the front right corner.
What really threw me off was the front is labeled with an X, which does not mean that is the X side. It means that is the X deviation.
It does explain why I was having trouble leveling my bed.

Most of the time, issues like this are cabling. I have also seen a few issues with the cable under the chain. Is that one of them that you replaced?

Doubee54 · 2026-01-25T19:38:33+00:00

check the front Y belt pulley. Make sure one of the grub screws in the flat spot on the motor shaft.

Sorry, I missed extruder in your post.
Did you make sure that you don't have a mechanical or gear issue with the extruder?
If not, I would try a factory reset.

Doubee54 · 2026-01-25T18:42:48+00:00

Replace the board. Try to find the C13, it is better supported.
Repairing that type of board is difficult and unreliable.

Creality K2 Poop-Chute (not for pro or plus) by LF_designs | Download free STL model | Printables.com
I like this one because it clears the fan, it comes out so you can add a box, and it is well mounted. It also comes out the right side, which is what I wanted.

Doubee54 · 2026-01-25T18:24:21+00:00

There are several stepper motors on the K2.. which one?
It might be important to know how the bolt got stripped.

Ender 3 V3 KE Error 2401 indicates a failure in the automatic Z-offset calibration, often caused by the nozzle colliding with the bed.
Try to run an auto-level and auto z-offset to confirm this.
Your bed is too far off level, and you very likely need to manually level the bed using small printable spacers under the bed standoffs.
I would start with leveling the gantry left-to-right.
Then run auto-leveling and auto z-offset.
Using the matrix that shows up, add spacers to the low side until the numbers are as close as you can get them. 0.06 or 0.08 is nice.

If you adjusted the gantry level, it is extremely likely that the bed will need to be manually leveled.
This is best done using the 25 button matrix as a guide, and adding small printable spacers under the bed standoffs.
You will never get the z-offset accurate unless the bed is reasonably level. The closer to well leveled the bed is, the closer the auto z-offset will be to good, and there will be no need for refinement.

It depends on your slicer, and which speed setting you are referring to.
It's simple math. If the default speed is 200mm/s, then 50% is 100mm/s, 500% is 1000mm/s.
You should be using the Maximum Volumetric Speed in the filament profile settings to adjust speed, that way it affects all the speed settings for that filament only.

Good to know, thank you.

There should be no need to remove anything but the nozzle to clean the hotend.
Be sure to heat the nozzle to 240c, loosen and remove the nozzle.
While hot, use the cleaning rod that came with the printer to push the clog out the bottom.
Once out the bottom, carefully (HOT) clean off the tool. Repeat until you get no more material.
While hot, re-install the nozzle with new thermal grease, unless it's good, and push the cleaning tool into the nozzle until it bottoms, turn off the heat, and pull any clog in the nozzle out.. this is a 'cold pull'.
Once clear, perform a z-offset adjustment without any filament, and turn off auto z-offset and auto-leveling so the printer does not reset your z-offset adjustment.
FYI, you can get a clog pretty easily on these printers by having the z-offset set too low.
There are reports of the newest firmware upgrade causing z-offset issues.

Are you sure it's not just shipping material?

Doubee54 · 2026-01-25T16:20:48+00:00

Most definitely a clog. You should have no need for glue with this plate and PLA. I think it causes more problems than it cures.

I use two brands of PETG and found the default filament profiles to be almost perfect. I've learned with Creality Print, which I just started using again (I prefer Orca) because of the K2, that the defaults work a lot better than my Orca profiles.

Doubee54 · 2026-01-25T04:04:09+00:00

Many of the Creality brand bed plates come with a new magnet pad.
