Summary

  • Issues with numeric keyboard repaired (MK4/S, MK3.9/S, MK3.5/S, XL)
  • Returned nozzle diameter setup (XL)
  • Printhead position during calibrations changed (MK4/S, MK3.9/S, MK3.5/S)
  • Cold pull (XL)

This is the stable release of firmware 6.1.3, which adds cold pull support for the XL, fixes bugs, and restores functions that were removed in the previous version.

Issues #4149 numeric keyboard repaired (MK4/S, MK3.9/S, MK3.5/S, XL)

There was an issue with setting numerical values for nozzle temperature, bed temperature, and print fan speed using the on-screen keyboard. Although the values appear correctly in the menu after input, the settings do not actually take effect—resulting in the fan not turning on or the temperatures not being applied. This problem did not occur when using the scroll knob to set these values.

Note: It is currently not possible to control the extruder motor movement via the on-screen keyboard.

Returned nozzle diameter setup #4151 (XL)

In version 6.1.2, the option to set the nozzle diameter on XL printers was unintentionally removed. We've acknowledged the oversight and have now restored this functionality in the latest update, allowing users to adjust the nozzle diameter settings once again.

Printhead position during calibrations changed (MK4/S, MK3.9/S, MK3.5/S)

Adjusted the print head position during printer calibrations to prevent it from colliding with the spool in the enclosure, ensuring smoother and safer calibration processes.

Cold pull (XL)

The Cold Pull method is a popular method used for unclogging or cleaning your extruder. Starting from this release, you can take advantage of a new feature that will guide you through the entire process using a step-by-step Wizard and provide assistance.
