I put my 1st 3d Printer together. Got it out of the box and put it together. Powered up all seem to be fine till I got to run the calibration (input shaping and auto leveling) the head moves up over to the left side of the printer and the bounces off the left side and goes down shaking. Does same thing when I do self check. Does same if I just do self leveling or just input shaping. I have replugged everything and checked for broken or bent pins on each connection. I have none. Here are some pics and video see what is going on. Anyone have any ideas why this would do this. I havenât printed anything. Brand new out of the box. Thank you, Brad
I returned the previous model and purchased the K1 Max instead. I suspect the issue was with the ribbon cable connected to the switch on the topâspecifically, the XY home switch where the print head aligns. It seems that the ribbon cable might have had some broken wires due to being pinched during shipping. The cable was tightly compressed when I unpacked it, which likely caused the problem.
Well that sure sounds familiar! There is clearly a problem at factory level with poor quality control.
I just bought my Ender 3 V3 Plus 2 days ago and set it up yesterday.
During the setup, there was a wire that slipped out of the tiny connector that is for the top limit switch.
I have to use my magnifying headgear and bright lights to see that the problem was the little metal insertâs tab was flattened towards the inside. It couldnât click in and due to being inside, it would hit the pin and not let the pin enter it.
I was able to fix that.
I let the printer do its calibration. That went perfectly!
When I went to run a test print of their benchy, first, the extruder was flying all over the place! Up, down, side-to-side. Just out of control. It returned that same 2022 error!
I researched the issue and it turns out that this code means a wire could be disconnected (some wire(s) not making contact), related to the right side.
I looked at the wires there and sure enough, the connector for the motor right there was totally out of its plug!! It looks like the bad design of having the spool right there, the thick wire rubbed against the connector and pulled it out!
I plugged it back in, making sure it was tight and all is working well now.
@Wazoo I know this is of no benefit now but hopefully my reply will help other users down the line. I have just experienced the EXACT same problem as you, I have been printing for around 10 years, only in small amounts, I only have 2 printers, I have actually just done the reverse of what you have done, I had a K1 Max, the V2, out the box, with all the upgrades, hot-end, unicorn, even fitted a full metal extruder due to problems, even with all Crealityâs upgrades from the initial model. after 2 months multiple parts, and more type in pieces than printing I was lucky enough to be able to wangle a return. my second printer is the Ender 3 V3 KE and I have to be honest it is the best printer I have ever had, hence why I purchased the Ender 3 V3 Plus, as it is a combination of the KE and the K1 Max.
Anyway back to it, I built mine, from what I can see, the exact same as you, and there in lies the problem. You would think that with the flat surface on the upper lateral support mount that it is meant to attach to the inside but in fact it attaches to the outside. The lateral support on the inside actually stops the head from touching the home switch, the juddering is the belt jumping teeth as the motors try to jam the print head to the left.
Picture attached for reference of anyone in the same boat. Hope it helps.
Thank you, I am sure that was what it was. It makes sense. I ended up buying a K1 Max, itâs a work horse. I have couple bars and always printing decorations or mods for the bars to work with or printing toys and games for customers to play with. I was so tired of waiting for K1 Max to get done printing for hours at a time I ended up buying a K1 SE witch is a work horse. Since July the K1 Max been running for 80 days and the K1 SE has been running for 40 day K1 SE bought it November 1st. I am debating on a K2 Plus but I think I will wait some time let them get the bugs out of it and figure out how to save waste. They waste so much filament. Thank you again and I do hope this helps others.

Iâm new to 3D printing and this is my first printer. After setting up the printer, I ran the self checks. When initiating the self-check tests, the printer head moves all the way to the left and then violently vibrate against the left side of the gantry. Then the following error appears on the screen.
Error
key:2022,Unknown exception during self check
After reading through many user suggestions, one user suggested manually moving the print head all the way to the left and ensuring that it âclicksâ the limit switch. I then investigated the unit and noticed that the limit switch is located towards the top left of the gantry (look for a black rectangular object with a small red rectangular button on it). I thought it was a little odd that the first thing the self-check did was move the print head all the way to the left - presumably to trigger the x-axis limit switch - but the print headâs initial position is at the bottom near the build plate. It doesnât first move up to where the limit switch is and then move to the left. Subsequently, before running any self-checks, I manually/gently position the print head towards the top of the gantry. This allows all the self-checks to run and complete successfully.
Is it normal for the self check to begin without first moving print head to the top of the gantry?
Also new to 3D printing & having the same problem on a âfactory refurbishedâ 3v3plus from _bay.
Printer firmware was on VS_1.2.3.8
Printer updated to VS_1.2.3.23 , but still had the same problem.
Does anyone know what is causing this problem.
A couple hours laterâŚ
I found the problem. Limit switch ribbon cable connector at the bottom left.
The ~4" pigtail from base terminates in a 4-pin connector with male pins.
One end pin of the connector was being pulled out slightly by stress on the cable.
I rearranged the cable & once the pin looked fully seated I reconnected.
Printer will home correctly now & passes all its tests.
