This direct drive extruder impresses with its weight and size. It weighs just 140g with a filament feeding force of 70N+. It also has a locking lever to load or unload the filament with one hand. Biese version stands out because it also includes a filament sensor with a programmable button for a follow-up function. With the sensored version you also have the option of installing a thermistor in the gearbox in order to be able to monitor this temperature, which is an advantage for remote monitoring. The filament feed has been optimized for the HF nozzles from Revo.
