A: You have completed MK8 extruder feeder configuration and assembly. Next steps will depend on how you are going to use this feeder, which extruder you will make using it. To complete assembly as direct drive extruder, you will need to use M6x1 threaded heatbreak tube, heater block, nozzle, heater and thermistor.
Q: What should M6 and M4 screws be for Mk8?
A: Large M6 screw should meet M4 screw, hold spring in a position and allow for tension adjustments. You have completed MK8 extruder feeder configuration and assembly. Next steps will depend on how you are going to use this feeder, which extruder you will make using it.
Q: How to calculate esteps for an aluminum extruder?
A: Calculating Esteps for the extruder is simple: Please take into an account filament gear driving diameter – 10.95 mm and calculate circumference of the gear – 10.95 x 3.14 = 34.38mm. Next calculation step will depend on the type of stepper motor you use and stepper driver setting.
Q: What’s the best way to install an aluminum extruder?
A: Use large button head M3 screw to hold bearing. Install Aluminum lever with M3x16 socket head screw. Screw on Lever to the extruder block completely and then loosen up just a little bit to allow lever movement. Secure filament drive gear on the stepper motor shaft with sets screws.
