I’m not sure if this is the x or y axis, but my creality ender 3 v3 ke has suddenly decided to not use the left half of the build plate.
I’ve tried all the levelling options I can think of (I’m very inexperienced so I don’t know many) and even tried doing a factory reset, but the same problem persisted.
I thought the ender would move continuously to the left until it hit that little switch to know when it was to the far left of the print space, but it doesn’t do that - even after doing a factory reset.
Please see the attached photo - the black line you see in the middle of the bed is where the printer tests the filament before starting the actual print. This should be really far to the left of the bed, not in the middle.
Does anyone know what I can do to fix this please as id really like to get back to creating some cool things with the printer again.
I wonder if you can manually move the printhead to being near the limit switch so that it triggers, one of my printers got a little confused and the bed would keep going down (ender 5 plus) until I manually wound it back to being near the limit, cured it. The V3KE, the bed should go back and twice click the switch, the head should move left twice and then go to the centre for levelling.
Im worried to push the print head too hard as i dont want to break something. Do you know what would happen if i physically pushed the print head hard enough to force the print head all the way to the left?
I dont want to break some component.
Can I upload a 2 minute video here?
I dont know if something the printer is doing is weird or not and its related to it not resetting its position correctly.
I realised the original video was ridiculously large. Over half a gig for a 2 minute video!
Ive reduced the size and changed the format. Can you let me know if this works please?
If not, I can upload a zip of it to dropbox and it might be easier to get it to play on your local computer if youd be happy with that?
Is there any way to check continuity on that limit switch with a multimeter? I would say the switch is stuck as the head moves to the right under power but never to the left
A couple things to try:
Get rid of whatever that is on the right side of the printhead. If it’s for the vibration sensor, you use that device one time, unless you change or modify something. It adds mass and may be keeping the printhead from moving right all the way.
You should be able to carefully inspect the micro-switch in the left side of the printhead. When actuating with your finger, you should see the little paddle arm contact a very small button on the microswitch, It seems it is somehow stuck ‘on’. Perhaps a small piece of filament is stuck in it. The board that it is attached to is easily removed and/or replaced. You can use a multi-meter to test it, but you will have to disconnect it.
See what happens if you close all slicers. Disconnect the cloud and your mobile device. A corrupt G-code may be causing this.
if you rooted your printer, go back to factory defaults.
A clue here might be what happened just before it quit working. Did have a clog? Or a print failure?
This answer won’t help with your question, but might help in the future. I, too, originally had a problem remembering which motion was X and which motion was Y.
I figured out that …X…was ACROSS (left /right/)… ( X)…and Y was moving AWAY from me (Y).
Anyhow, it keeps this old mind straight. I hope it helps you.
Thank you for the advice.
It was working fine up until this happened. I’ve checked and the switch appears to be working correctly, there’s nothing jamming it or stopping it from working.
I asked one of the creality team and they suggested flushing the firmware. I tried following their video to do it, but the printer wont accept the new firmware as its the same version number as the one that’s currently installed.
I haven’t rooted the printer, and I already tried resetting it to factory defaults, but it keeps doing the same thing.
I do have another of the boards that everything plugs into. I can try taking everything off the current one and installing the new one to see if that works, but id like to try this idea of flushing the firmware - does anyone know how to force the printer to install firmware even if its the same version number as its current firmware?
