Complete metal MK8 extruder for 1.75 mm filament without motor.
Motor 400 steps NEMA17
Bipolar, four-wire stepper motor.It has a resolution of 400 steps per revolution (0.9 degrees). Powered by 3.0 V, it consumes 1680 mA for the coil. The torque is 4.4 kg * cm (0.45 Nm).Dimensions are 42 x 42 x 48 mm (NEMA 17).
Version 6 has been refined construction based on the experience gained from previous heads. Improved and improved operation of new filament types such as NinjaFlex. The smooth and undistorted travel of the filament provides a PTFE tube that enters the head but does NOT reach the hot zone of the head, so it is still a fullmetal head. The head can be operated at temperatures of over 300C with thermocouple instead of thermistors.
The heating block allows the target operating temperature to be reached quickly. The head is warmed up from 20C to 200C in 65 seconds and can be stabilized at 0.5C
The changed design of the cooling element and the new fan mounting also made the entire head shorter – the verge 6 has only 62 mm in length and reduced weight.
