DEMO PRECOMPILED VERSIONS

To incentive the test and the feedback of the firmware by the community I'm releasing these demo firmwares compiled using the current sources from the main repository https://github.com/mriscoc/Ender3V2S1

These experimental DEMO pre-built firmwares are restricted to 1 hour of print time, so they are not intended for production but for testing purposes only.

Currently I don't have other hardware/boards to test other configurations, so I need your tests to be able to post reliable releases.

Warning

This is a placeholder. Do not download the zipped source code from here, if you want to build your own firmware, download the zip file from the main page of the repository and use the Configurator to create proper configuration files.

Depending on the positive feedback or bugs found and solved I will release unlimited official versions. Please use the discussion page in the main repository to leave your feedback: mriscoc/Ender3V2S1#1226

Sorry, I'm a little busy these days, so I must prioritize support to sponsors and subscribers, my free support will be very limited. Some special composite versions (which include more than one feature) are sponsored versions or compiled as requested by subscribers, so the unlimited version may not be available as a public release.

Special support for TJC Displays

This special release has support for the TJC displays, including thumbnail preview and fixed mesh viewer fonts for show the leveling values. The Precompiled TJC versions are in the assets section at the end of this release page.

Note

Some TJC displays also need a new display firmware to boot and show previews, download it from: TJC firmware update

Warning

This is a placeholder to get the precompiled versions for TJC displays. Do not download the zipped source code from here, if you want to build your own firmware, download the zip file from the main page of the repository and use the Configurator to create proper configuration files.

TJC displays cannot display small fonts, so the bed tramming wizard and mesh viewer may lack numerical information.

Set your slicer to generate a square thumbnail from 100x100 to 200x200

Use the G-code sample file, to test your printer's ability to show previews.

TJC can't draw lines very fast like DWIN, so a compromise must be reached between time and drawing. It can draw full circles but at slow speed or draw the lines interleave for faster circles. I choose for now the last option; it is not a glitch or bug.

CV Laser Module (CVLM)

Warning

This is a placeholder. Do not download the zipped source code from here, if you want to build your own firmware, download the zip file from the main page of the repository and use the Configurator to create proper configuration files.

This special release of Professional firmware supports the CV LaserModule from Creality compatible with the Sprite extruder mount of the Ender 3 S1 (Pro/Plus) with a supported display unit. This firmware allows you to switch between 3D printing and laser engraving functions.

Input Shaping (IS)

Warning

This is a placeholder. Do not download the zipped source code from here, if you want to build your own firmware, download the zip file from the main page of the repository and use the Configurator to create proper configuration files.

Currently Marlin is experimenting with Input Shaping (IS) support. You can follow the progress of that feature here: MarlinFirmware/Marlin#24797

From that post:

Use record and replay of Bresenham algorithm calculations to effect ZV input shaping for X and Y axes.
It's quite rough and ready at present. At least the following are on my mind:
It requires record buffers which consume more SRAM than I like. Longer term there are ways of doing this with no buffers. The "echo" comes after the main signal.

There are mixed reports about if it is working with stock Creality boards. This feature is enabled in this release, its parameters will be set using a menu in Control/Motion or using the M593 G-code.

Special Builds for Marlin #05 temperature sensor and "All Metal" heat break with 300°C support (E3D V6 Volcano).

Warning

This is a placeholder. Do not download the zipped source code from here, if you want to build your own firmware, download the zip file from the main page of the repository and use the Configurator to create proper configuration files.

The T5 versions have support for the E3D V6 Volcano hot ends and any heat block that have a Marlin #05 temperature sensor as 100kO ATC Semitec 104GT-2/104NT-4-R025H42G thermistor (E3D, Hemera, Slice engineering, etc.)

Thermistor #5 calibration table

The upper limit of the calibration table of Marlin for the type 5 thermistor is 713°C. That table supposes a linear behavior from 300 °C to 713 °C, but there is no guarantee of accuracy temperature measurements above 300°C, the current max user selectable temperature is 285°C (300-15 overshot protection) it is possible to increase the selectable temperature by using the custom G-code C104.

// R25 = 100 kOhm, beta25 = 4267 K, 4.7 kOhm pull-up
// 100k ParCan thermistor (104GT-2)
// ATC Semitec 104GT-2/104NT-4-R025H42G (Used in ParCan)
// Verified by linagee. Source: https://www.mouser.com/datasheet/2/362/semitec%20usa%20corporation_gtthermistor-1202937.pdf
// Calculated using 4.7kohm pullup, voltage divider math, and manufacturer provided temp/resistance
constexpr temp_entry_t temptable_5[] PROGMEM = {

Special Builds for Marlin #13 (3950) temperature sensor and "All Metal/Sprite Extruder Pro" heat break with 300°C support.

Warning

This is a placeholder. Do not download the zipped source code from here, if you want to build your own firmware, download the zip file from the main page of the repository and use the Configurator to create proper configuration files.

The T13 versions have support for the HT-NTC100K thermistor or any heat block that have a Marlin #13 temperature sensor and a All Metal heat break. The Sprite extruder Pro could be compatible with this version (there isn't an official confirmation) see here: mriscoc/Ender3V2S1#218.

Marlin TEMP_SENSOR number:

 *    13 : 100kΩ  Hisens up to 300°C - for "Simple ONE" & "All In ONE" hotend - beta 3950, 1%

Note for Extruder Sprite Pro users:

This version only sets the proper thermistor for that extruder but not the physical settings because those depend on your printer, fan duct, etc.
To adjust the correct position of your nozzle and probe use this guide: https://github.com/mriscoc/Ender3V2S1/wiki/Calibration-Guides

Printing temperature limit:

The stock upper limit of the calibration table of Marlin for the type 13 thermistor is 300°C, So the editable limit will be 300-15 (overshoot) = 285 °C. However, the latest precompiled versions are loaded with a extended Steinhart- Hart regresion table, that allows us to extend the maximum range of operation with better accuracy, for enable higher printing temperatures use the special G-code C104. The image shows why overshoot protection is necessary when there is a PID control, the temperature shouldn't go beyond the absolute manufacturer limit.

To reach an efective temperature of 300 °C it is possible to use the custom g-code C104:

C104 U1 T315  ; set absolute limit to 315 °C (300 + 15 overshoot)
M500          ; save settings

Linear Advance (LA)

Warning

This is a placeholder. Do not download the zipped source code from here, if you want to build your own firmware, download the zip file from the main page of the repository and use the Configurator to create proper configuration files.

Linear Advance Documentation

This special feature is experimental for the stepper's drivers in standalone mode (Creality 4.2.2, 4.2.7, F1, F4) and is here for your test. It is possible to enable it by editing the configuration file, of course, Linear Advance can be used normally in boards where it used to work. The precompiled binaries for LA have Classic Jerk and S-Curve Acceleration disabled and Junction Deviation enabled.

Background

There was an old problem with the configurations of the drivers that Creality uses on its boards. LA was incompatible with drivers in standalone mode.

 #define E0_DRIVER_TYPE TMC2208_STANDALONE  // Ender Configs 

Some months ago, that was resolved by this: MarlinFirmware/Marlin#24533
