Add config for Creality Ender 3 Neo and Ender 3 v2 Neo

[Matombo]

Creality now sells pre upgraded Ender 3 and Ender 3 v2 with the apendix "Neo".

The config relevant changes are:

• A magnetic print bed, so it has no more clips holding the bed that requires the machine_disallowed_areas
• An automatic bed levling sensor, so i added the automatic bed levling G29 code to the default startup gcode

[Matombo]

I spotted an error I made: The Neo also has a different Printhead so the printhead settings propably need to be adjusted too.

I don't have a original ender 3 neo printhead here, so i can't messure it :(

Can you sync your fork, with our main. We have added a printer-linter tool for our printer definitions and profiles. This should help us with processing our PR's. It performs some standard diagnostic checks and apply auto-formatting on the changed files in this PR, but you can also run it locally. See https://github.com/Ultimaker/Cura/tree/main/printer-linter

If it finds issues for which it knows a fix it should post a comment with that suggested fix such that you can easily commit that fix if you're okay with it. But please use commonsense with the suggestions because the tool is still in the early stages of development

Hey @Matombo, did you manage to get your hands on an original Ender 3 Neo printhead to measure?

Nope, still only have a non-neo to neo upgraded printer but with the original non neo printhead.

Hey @Matombo, I'm going to leave this in draft until someone can measure the Ender 3 Neo printhead. Please hit "Ready for review" once this is done.

Thanks 👍

Those are the values from the printer profile inside the Creality slicer.

I tested it with my Ender 3 v2 Neo and so far it seems to work just fine.

Hello, could we please get this merged in? I've tested manually adding the settings with my Ender 3 v2 Neo and they work - it would be good to have it part of Cura.

I don't know if this is helpful but I watched a YouTube video about the Ender-3 V2 Neo and they said to put G28G29 for home (this is the video). I have been using my printer with the Cura setup described in the video and its worked great.

Just a heads up. I bought an Ender-3 V2 Neo in late October of last year and there seems to be some confusion of the bed size. The dimensions Creality provides for the Neo is also what they refer to as the "print area" but the actual size of the print bed is 235mm x 235mm which I have personally confirmed.

This website theorizes it's due to the original design of the Ender 3, which used clips to attach the build plate. Since the Neo ships with a magnetic surface, that is a significant amount space being potentially wasted.

I bring this up only because I have been using the Ender-3 / Ender-3 v2 profile in Cura, which by default comes with a X and Y width of 235mm. In fact a well known creator in the 3DP community preferred using the regular Ender-3 Pro profile and setting the X and Y from 220mm to 235mm manually. I don't recall the specific reason he mentioned as to why, but it was a technical one.

I'm going to try and build the Xmas tree branch today with this pull request and do some tests on my V2 Neo.

I’ve been using prusaslicer because it has a profile for the ender 3 v2 Neo and it works great so that could be used for inspiration.

Hello, Do we have any updates on this?

[igorluppi]

Is there a timeout limit a draft can be up? May someone else create another PR with the required updates?
