Ender 3 V2 stuck on Autohome/Motors unresponsive
I hope you agree with me when I say: best dutch oven for bread
Dutch ovens style cooking is not a new concept.
Rather it has been a part of the various cooking methods that have evolved from cooking in clay enclosed pots to the slow cooking that we know now in the form of dutch ovens.
It can be used to make a variety of delectable dishes such as roasts, programmable thermostat under fifty
briskets, and even bread, yes bread!
Thanks for your feedback, we have upgraded all the firmware in the Creality download, please check if you need., Thank you
@admin I just wanted to point out that this fixed the issue for me. I had downloaded the supposedly latest firmware from the official website which left my device unresponsive in terms of motors. The linked 1.0.2 resurrected my device and left me with a flawless first print.
Shame that the official download seems to cause issue. Otherwise it has been a pretty cool experience.
Ok … it took a bit of reading, testing, and … pulling. Here is what happened, maybe this helps someone else like me.
- I have a new Ender V2, with the BLtouch addon installed from the start
- My problem was, nothing was moving. Auto-homing stuck.
This is what went wrong:
- I downloaded the firmware linked from the BLtouch page. This is a Google Drive link, to an V4.4.7 firmware for BLtouch 1.3.1 (V4.2.7-Ender-3 V2-32bit Mainboard-Marlin-2.0.1-V1.3.1-BLTouch-TMC2225). This is the only firmware in that folder for Ender 3v2, it is "official", so it must be the correct one! … WRONG!
- I found some other "official" download links, giving me options like : 4.4.7 and 4.4.2 … 1.1.1 and 1.3.1 … I tried them all, some just beeped, most got stuck.
- After a while I flashed the original 1.0.1 (non BLtouch) version and figured out that e.g. X axis is moving when triggering manually.
- So opened up my board again, found out that I had an 4.4.2 board, assumed that 1.1.1 was the right BLtouch version (due to the clue "without adapter board", as I had none)
- Motors moved, just now downwards. Autohoming started, but got stuck in the middle (I assumed it waited to move down, but it somehow did not)
- I read some information about the firmware blocking downward movement if the Z-axis switch triggers (which is replaced be the BLtouch here) I also recalled youtube video that sometimes the BLtouch gets stuck. It is a magnetic mechanism, which gets pushed down and then pulls up when pushed upwards. My BLtouch was light up red.
- I manually pulled out the pin, just to see what happens. And carefully pushed it back in. The BLtouch turned off …
- I retried autohoming and it started with pushing down the pin by itself.
So aside from the firmware issues, it looks like the BLtouch probe simply was stuck a bit too much. Maybe because it wasn't used yet, maybe because of another reason. Manually pulling it out made it work.
However, I think the following things have gone horribly wrong here
- The BLtouch product page should not link to a google drive which contains only one version of the firmware, which might not be the correct one for everyone.
- The firmware should ideally verify that it is running on the correct board and warn the user if not.
- There should be clear indications on the BLtouch and the Ender which revision they are … opening up the board compartment isn't a good idea to find out about that. Any my BLtouch probe actually shows the version 3.1.
- On the firmware download page there should be some clear explanations which version to download, its a mix of versions … and when you are new, you have no clue. And users will always pick the "newest" version, so 4.4.7 over 4.4.2 … because it doesn't mention that this is the board version and not the firmware version.
- Ideally there should be an error code displayed when the auto-leveling fails … and error code which you find again on the web page … which explains that this might be due to "cause 1 … 2 … 3" … and one of the tips should be to "carefully pull out the pin of the BLtouch"
That was my first day with the Ender 3 v2 … tomorrow will be better I guess
I just assembled my Ender v2 with BLtouch and have the same issue. Nothing moves.
Flashing the 1.0.2 linked below allows me to move the motors again, however it doesn't seem to be a BLtouch firmware.
So are newer firmwares or BLtouch simply broken?
Did you do a RESET EEPROM after flashing new firmware ?
This menu item can be found under configuration > advanced configuration > initialize EEPROM < ?
I understand this frustration. My machine is brand new. It worked on day 1. Did some test prints. Worked fine. This morning, blank screen. Did some sleuthing and found an online solution. It fired back up! But, before I tried printing anything, I wanted to make sure it was still leveled and correct after the firmware flashing. Went to auto-home and it's stuck on the auto-homing mode too. I noticed that as of this morning (03.08.2021) there is a new firmware update for the LCD screen. Not sure if this is for the auto-homing issue or the blank screen. Any thoughts, ideas or fixes to get the auto-homing to finish it's procedure and not be locked up?
I'm having this same problem, and updating the firmware did nothing... I am really disappointed in Creality customer service. I read a bunch of reviews that said this was a good 3d printer to get as a beginner, but that is turning out to be very untrue. I have been emailing with customer service as well, and they are no help. I am beginning to think I will never figure this out and I just wasted 270 dollars.
I’m having a similar issue. Fully assembled my new Ender 3v2. Following the instructions, I tried auto homing. The print head repositions to what looks like the spot that would be 0,0 on an x y coordinate and then the display is stuck at “Auto homing...Please don’t other operation” and the display stays there. I checked the voltage (115) and the x/y cable. Firmware is 1.0.2. I have not opened the cover to see if the motherboard is wired correctly.
@admin I had exactly the same problem. I hadn't tried my printer, I just built it and then flashed it to 1.3.1. When I powered it up none of the motors worked. They all locked up for 2-3 seconds and then released. That was all it did. The bed heated, but nothing else worked. To keep it short, I flashhed it down to 1.0.2 and everything worked. Suffice it to say that I'm a very happy camper! I hope that this works for those of you with the same problem.
My printer is the Ender 3 v2. The original flash was 1.0.1.
did you fix it? having the same issue!
- Please check whether the power supply voltage is adjusted to the local voltage
- Refresh the motherboard firmware
Ender-3 V2-Marlin-2.0.1 - V1.0.2.bin
3, Refresh the display firmware
