Calibration kit
Warning!
The calibration kit is required before updating to the firmware version 0.3.0, to be released October 2025! After updating the firmware, the machine has to be calibrated with the new calibration kit.
This new calibration kit is an improved version from the previous calibration kit that consists of four rods. This new kit is provided to calibrate the sensor more accurately.

3mm "Long nozzle"
This new and improved nozzle design simplifies the nozzle change procedure and reduces the chance of leaking.

Filament stabilizer
This stabilizer is a new tool to improve the filament stability at the filament sensor. Filament can potentially move and wiggle by the cooling fans, compromising the sensor accuracy.

Tensioner spring
This new tensioner spring is tighter to improve the tensioner wheel grip on the filament when spooling. It can be exchanged, when extruding stiff materials.
