Special Configurations

In this repository there are the configuration files for several Marlin firmware features for the Ender3 V2/S1 printer, the main project files are in the firmware repository: https://github.com/mriscoc/Ender3V2S1

These special configurations and releases are sponsored by donors.

How to request a custom build

Please check the suscription levels on Patreon, there are levels that allow to request custom compile. Patrons from Patreon platform can request a configuration sending a message. If you made a equivalent donation through Paypal, please reply the message that I sent you or use any of the other communication media (Facebook, Telegram) providing the name used in Paypal. I'm happy and grateful for the contributions but please don't confuse that with paid work. I do what is possible in my little free time, be aware that a donation does not give you the right more than my thanks, a specialized job like coding and compiling a custom firmware could be a work quoted in 3 digits. Github also have a Sponsor platform.

Creating your own custom configuration

It is now possible to use an small Python GUI interface (Professional Firmware Configurator) for generate the configuration files, after downloading the repository execute the Python file Configurator.pyw:

On Windows, .pyw files should be opened by pythonw.exe by default.

Select the printer, board, leveling, thermistor (Ender's stock thermistor is T1), features and press the set config button; write a name for the configuration or press Auto button for fill the name automatically, that name will be used as a folder for storage the configuration files and also as a custom printer name in the firmware, then press the Generate button to start the creation of the configuration files. You can open the .json files in _printers, _boards, _features, etc. folders to know how each option in the Configurator works.

Compiling your firmware flavor

From the created custom configuration folder, move Configuration.h and Configuration_adv.h files to the Marlin folder inside of your project folder downloaded from the repository https://github.com/mriscoc/Ender3V2S1; move the platform.io file to the root of your project folder. Keep your path short, the compiling tools don't like large paths.

Follow any guide about Marlin compile to get your firmware binary: Install VSCode, then inside of VSCode install the extensions: PlatformIO and Auto Build Marlin. Open your project folder in VSCode and compile by using Auto Build Marlin. Remember: RE -> RET6 with 512 kB flash, RC-> RCT6 with 256 kB flash, do not use xfer and maple is a deprecated framework for some incompatible STM clones.

Custom features

Advanced user can create a custom configuration calling directly the CreateConfigs.py Python script with the following parameters:

CreateConfigs.Generate('CustomConfigName', ['Printer','Board','Features',...])

To create Ender3V2 Configuration files with a BLTouch and UBL support it is easy to write a little Python script to call the above function:

#!/usr/bin/python
import CreateConfigs
CreateConfigs.Generate('Ender3V2-422-BLTUBL', ['Ender3V2','422','BLT','UBL'])

For have a special build you can provide a config json with only your personal choices, for example: for get a special build for a Ender3V2 printer that have a hotend volcano, bltouch and 4.2.2 board it is necessary only write a Volcano.json with this content:

{
"Configuration_adv.h" : [
],
"Configuration.h" : [
  {
    "op": "CustomVal",
    "searchfor": "TEMP_SENSOR_0",
    "value": "5",
    "comment": "Volcano thermistor"
  },
  {
    "op": "CustomVal",
    "searchfor": "HEATER_0_MINTEMP",
    "value": "5",
    "comment": "Volcano thermistor"
  },
  {
    "op": "CustomVal",
    "searchfor": "HEATER_0_MAXTEMP",
    "value": "300",
    "comment": "Volcano thermistor"
  }
],
"Version.h" : [
]   
}

Put the Volcano.json file inside of the _features folder, then request to the CreateConfigs.py to build a configuration with CreateConfigs.Generate('MyCustomConfigName', ['Ender3V2','422','BLT','Volcano']); the last "Volcano" will overwrite the necessary values in the configuration file, you can also use the GUI, your custom .json file will be listed as a custom feature.

For write your json file take note that the CreateConfigs.py script supports these basic operations over the configuration files:

InsertAfter: allows to insert text after match a given mask.
Custom: allows to replace text after match a given mask.
CustomVal: allows to replace simple (numeric, booleans, etc.) values.
Enable: allows to enable a feature.
Disable: allows to disable a feature.
Replace: allows to replace a mask with other text.

For example to change the default tramming points you can write in the "Configuration_adv.h" section of the json the command:

  {
    "op": "Custom",
    "searchfor": "TRAMMING_POINT_XY",
    "mask": "{.*}",
    "value":"{ { 29, 29 }, { 299, 29 }, { 299, 299 }, { 29, 299 } }"
  }

For disable Multiple probing you can write in the "Configuration.h" section of the json the command:

  {
    "op": "Disable",
    "searchfor": "MULTIPLE_PROBING",
    "comment": "Custom disable"
  }

The comment line is optional. Masks are in regex format, use the provided json as examples.

Debugging Configurator errors with IDLE

If the Configurator doesn't open, load it into the IDLE Python editor and run from there, the possible error will be displayed in the IDLE Shell.
