Hi, I’m very new to Creality, but have been around computers for longer than I care to think about, so not a complete newbie.
Bought a ender 3 max neo, not working, and the person who had it had clearly given up after spending some time with support, they never did get it working, and bought another printer and they sold this one as not working, which I knew, so I’m now trying to get it working, and getting royally confused in respect of the firmware it’s supposed to have.
So, from the beginning, when I put it on the table to see what was or was not working, the fuse holder was missing, but in a bag of bits that the previous owner had put with it, there was a new socket, which had the fuse carrier in it, and there was also a spare power supply, and a main board cooling fan. and a good few screws either loose or missing, so I decided that a closer inspection was called for before applying any power to it.
The check was interesting, one of the PSU’s was set to 115 volts, which made me wonder if maybe they’d missed that critical step, and possibly blown something, so I went a bit deeper, and checked the PSU to see if it was working, and the right voltage, with the boards disconnected, which it is, so at that point, I checked the motherboard and display, to see if there were any issues like a blown fuse on the board, it’s good, so I then went a bit deeper, and discovered that the display also has a SD slot for updating, but at that stage, I didn’t worry too much, and put everything back together, to see what happened, and on powering it up, I got a Creality display, but nothing beyond that.
In a box in the garage, I also have a Ender S1 in parts, and looking at it, the display looks similar, so I tried that display on the Ender 3, and got a result, it powered up and the basics are working, it will home, and do a basic bed level, but clearly, it’s not going to have the right software or configuration on it, so at that point, I went to the creality site, and downloaded what in theory is the right software for this device, but despite doing the right things, it’s not loading the firmware from the SD card on power up, and when I got into digging a bit deeper, I’m not sure if I’ve got the right firmware for the configuration that this machine is built with. The motherboard is a version 4.2.2, and there’s a T8 sticker on it, the sticker on the back of the board ,has 1000069170, E-3 MAX NEO, 2101020199 on it, and the QR code comes up with 2101020199A240414189A,
The label on the display is TJC4827X243_011N_P04, and the QR code comes up with HXEL****XSEK15ELV1.65+10807012
So, the basic machine seems to work with the S1 display, but refuses to allow me to load the replacement firmare in the non working display, and I’ve not gone near the mainboard to do anything firmware wise at the moment.
The label on the box says it’s an Ender 3 Max NEO, a clatter of Chinese characters, and then UL/ROHS and under the bar code, EUW030-1001020445A, the last part of that number is then repeated on the next line. The packing list number is RVEUW030-231226-0002-66, the QR code on the top of the motherboard housing is 100006284633423LYSX.
It didn’t come to me with an SD card, I’m not even sure if it had one from new, and there wasn’t a manual either, at some stage, I think I will need to check the set up of the Z axis, as the belt seems very loose, but that’s a little down the road, the first thing is to try and determine if I’ve got the right software, and how to load it, or if I need to get a new (later ) motherboard, or possibly a display, with how much worked using the S1 display, I don’t want to get boards if the issue is a wrong firmware.
So, help please, where do I go from here, I’d like to get this working if I can, as I have plans to do some 3 d printing of model railway track, and this looks like it could help with that.
Thanks
Steve
