This is the stable release of firmware 6.10.1 for the Prusa XL+ and XL, introducing firmware support for the hardware of the new XL+ edition. Because the XL last received firmware 6.4.2, this release also carries across everything introduced for the other Prusa printers in the 6.5.1, 6.5.3, 6.5.7, 6.6.0, 6.8.1 and 6.9.0 releases, which is why the list of changes is unusually long.
Support for the new Prusa XL+
Firmware 6.10.1 adds support for the hardware that ships with the new XL+ edition. The printer recognises which variant it is at startup and configures itself accordingly, so no manual selection is required; the detected type is shown in Settings → Hardware.
The XL+ brings:
- A tool offset sensor, replacing the pin-based calibration. It is described in its own section below.
- A Nozzle Wiper, which physically wipes the nozzle clean before mesh bed leveling and during the tool offset calibration. The wiper replaces the original nozzle cleaning procedure.
- GT1.5 belts.
- A new print fan.
- Additional cooling fans for the mainboard and the heatbed electronics.
- High-flow nozzles as the default nozzle type.
NOTE: G-code sliced for the XL can be printed on the XL+ without changes.
Contactless tool offset calibration [XL+]
On the XL+, the calibration pin is replaced by an inductive sensor mounted on the print bed. Each tool's XY offset is measured by sweeping the nozzle across the sensor coils without touching them; the Z offset is then measured by touching the nozzle down.
The tools are heated during the measurement so that the result accounts for the thermal expansion of the nozzle. With the Nozzle Wiper installed, each tool is also wiped during the measurement.
Nozzle thermal expansion compensation [XL/+]
The printer now corrects for the nozzle length changing with the temperature. Please note that this feature is in the early stages of development.
The bed moves down after finishing, pausing or stopping a print [XL/+]
When a print finishes, is paused or is stopped, the bed now travels down so that the printed part is easy to reach and remove.
