Compiling and Leveling problems with DW7.4.7 an Ender3 V2-BLT-V422 -- SOLVED :) --

[rstalde]

I have compiled the DW7.4.7 version for an Ender 3 V2 BLT with a V4.2.2. Board
Thereby 2 problems occurred:

1. compiler error in line 691, port assigned twice.
   I could solve the problem myself: the port LCD_SERIAL_PORT must be 3 (by the way, the same error is also present in DW7.4.6 ;))

2. after homing, the hotend is > 10 mm above the print bed, but 5 mm are displayed.
   It is not possible to set the hotend to the required height for printing (setting range not sufficient / assumed height wrong).

10.07.23 The problems are solved!

Attached is the configuration.h file with all changes.
The configuration was tested with an Ender 3 V2 as well as with an Ender 5 Pro. Both with Ender 4.2.2 and BLToch with holding brackets from Creality.
The changes are marked with //RST. For type dependent parameters the type is additionally indicated. For changed values, the original value is usually given.
Have fun at testing ;)

Hi there. I hope you don't mind if I ask an unrelated questions. I have an Ender 3 V2 with 4.2.2 motherboard, CR Touch, BTT smart runout sensor, and a touch screen upgrade kit I bought from Amazon. It looks like the touch screen only works with the Creality firmware because Marlin doesn't have support for those screens. I'm not sure what DW7.4.7 is for, but there is this video of a guy that was able to install InsanityAutomation's firmware and make it work on an Ender 3 Max with the same motherboard and screen I have, which give some hopes. Does anyone know whether there is a firmware from InsanityAutomation that supports all those features above?

In response to your question, I looked at the current version 7.4.8 (Bleeding).
There, a touchscreen is specified as a special configuration.
However, you would need to have some configuration file customization skills to use these configurations.
Since I myself have no interest in using touchscreens on the printers, I won't bother with this configuration any further, though.
I am currently using the current version of the original Marlin.org software in customization for various Ender 3 / 5 printer configurations. (An extremely unpleasant and widespread bug has been fixed there only a few days ago, hence this step. ;))
