This is the stable release of the firmware 6.1.2 adding support for upcoming printers. There are also multiple upgrades and improvements for the existing printers.

Note: This firmware 6.1.2 is a direct successor to the firmware 6.1.0. Version 6.1.1 won't be released to public as a major bug was found and is fixed in 6.1.2.

Support for MK3.9S and MK3.5S printers

This release extends compatibility with the latest printer models, ensuring access to new features for MK3.9S and MK3.5S printers.

Numeric keyboard

You can now use a numeric keypad to enter numerical values by simply touching and holding the adjustable numeric field value, e.g. move axis or nozzle temperature.

Custom names for steel sheet

Users can now assign custom names to their steel sheets via touch keyboard.

User-configurable hostname

Users can now define their own hostname for the printer.

Binary G-code check

A new binary G-code validation process has been implemented, which enhances the security and reliability of print operations. This feature checks the integrity of binary G-code blocks during printing.

ESP firmware flash during boot (MINI, MK3.5/S, MK3.9/S, MK4/S)

Flashing the ESP module now occurs automatically during each boot if the firmware version doesn't match, eliminating the need for manual updates via the menu. The runtime process that previously handled this has been completely removed. Now, if an ESP module is inserted during printer startup, it will be automatically flashed with the new firmware without any prompts.

New bootloader 2.3.5

Fixes the issue where the .bbf file was being requested on the USB drive for MINI printers.

Network Status screen

A new Settings menu screen that gathers the most important information about network status and connectivity to key servers.

Steel sheet name in footer (MK3.5/MK3.5S)

For MK3.5 and MK3.5S printers, the name of the currently loaded steel sheet is now displayed in the footer of the user interface.

Powered Z-motors during calibration procedure (MK series)

During the gearbox calibration process, the Z-motors will now remain powered, leading to more accurate and consistent calibration results. The motors are then powered off again after the calibration is completed.

Default nozzle diameter set to 0.4 (XL)

The default nozzle diameter setting for the XL model has been adjusted to 0.4mm.

Japanese language (MINI)

Added Japanese language support to the MINI, enhancing accessibility for Japanese-speaking users. The firmware version with Japanese is available as a separate build, just like with other language versions on the MINI printer.

Bug fixes

  • fixed M73 report #4089
  • fixes for unexpected USB disconnection
