Single tool G-Code on a multi-tool printer (XL)
Until now, multi-tool printers have always picked the first tool when given a single-tool-specific G-Code. Starting this release, the printer uses a preselected tool for printing single tool G-Code. Users can preselect the tool from the Menu -> Control -> Pick/Park Tool.
Selftest extension (MK4)
Nextruder allows for user-friendly nozzle changes, however, some nozzles have different thermal properties, which might affect the behavior during heating and lead to failures in Selftest.
Starting 4.7.1, the user can make the system aware of the hardware setup in Menu -> Settings -> Hardware -> Nozzle Type [Normal/High Flow] This setting can be also adjusted immediately after a failed Selftest with an option to repeat the test.
Support for xBuddy revision (MK4)
This firmware release is extending support for the upcoming xBuddy hardware revision. The system recognizes between the boards automatically and there is no need for user intervention.
The reason for a revision is due to a change in chip suppliers, however, there is no difference in performance between existing and upcoming hardware revisions.
Known Bugs
- In case of a hotend fan error (e.g., filament stuck in fan blades) is not properly resolved (e.g. filament removed from the fan) and the user selects to continue with the print anyway, the printer might get stuck and the only option is to stop the print.
- A hotend fan error followed immediately by a Print fan error can lead to a system loop in the error screens.
