Ender 3 Max Neo G-code configuration file

Is your feature request related to a problem? Please describe.
I have an Ender 3 v2 and it's working great with this firmware, but I'm thinking of buying an Ender 3 Max Neo, which has the important upgrades an Ev2 would want, plus a larger bed size, and it's on sale:
https://store.creality.com/products/ender-3-max-neo-3d-printer?spm=..page_2510923.header_1.1

I see it is running a 4.2.2 board and doesn't use a touch screen, so it should be fine. However, I see there are quite some settings to change to get a larger bed size. It would be nice if it had an easy support for the 300mm printers with a custom build or something.

It would also be nice if the website listed on the front page the set of Creality printers that should work out of the box. It's a little confusing the documentation only mentions two models. I'm new to this codebase (and printer) and it's comforting to see in print what is known to work.

I decided to buy the Ender 3 Max Neo and sell my Ev2. A custom build, saving the manual configuration, would be awesome.

You can write a configuration file: https://github.com/mriscoc/Ender3V2S1/wiki/Configuration-files

The machine arrived. The build is trivial compared to the E3v2, I did the basic mechanical checking everything I know of. It was well built except the eccentric nuts were too tight.

I installed the professional firmware, with the below configuration file.
However, the bed tramming wizard didn't grab the heights from reasonable positions.
Also, when I would move the X axis to 300 mm, it wouldn't move the full width.
I thought maybe the steps per mm was different, but I saw in the Creality firmware it uses 80 for X and 80.1 for Y, so perhaps it is something else? I checked and the board is a 4.2.2

Did you edit you machine physical settings in the Advanced menu telling it your xyz dimensions?

[KeithCu]

I checked that they were 300mm after applying the config file.

[mriscoc]

Set the mesh insets after change machine physical limits

How does this look?

It seems to be good.

I found on the Max Neo that the X min position is -20.

I am using this which generally works but might not be correct regarding the Max X. I was having problems with using 280.

Why did you disable powerloss recovery, out of curiousity?

[cprgolds]

@RealDogDad - Take a look at this video and you will see a reason to disable power loss recovery.

thank you so much for this took me a bit to rap my head around the exact things to do but pronter face and your g code worked so far. bed mesh is off on the low side of x axis and y could go back about 10-15mm back. thanks again to everyone.

[mriscoc]

For the custom C-codes you need a special version of Pronterface: https://github.com/mriscoc/Pronterface-PFEd/releases Normal Pronterface will filter any non-standard Marlin G-codes, so if you try to use configuration files with C-codes, they will be removed and only the standard codes will be sent to the printer.

[ONEEYEWILLIE420]

the ver. i had was able to accept it. im just learning so takes me days to do what some can do in seconds hahahaha thanks sir.

version for macOS?
