So according to E3D customer service, the V6 is designed to have higher back pressure than the MK8. This leads to underextrusion with PLA and all kinds of problems unless you increase the temp by 30 - 50 °C so it will heat the filament faster and reduce the back pressure. They recommended getting a geared extruder such as the titan when I contacted them. Why none of this is mentioned on the V6 product page I have no idea, but I am not about to spend the cost of the V6 again on an E3D extruder unless it is truly the only option. I would imagine one could just replace the stock extruder motor with higher torque.
Does anyone know the max amperage motor you can replace the stock extruder motor with?
Is a 2 A NEMA 17 too much?
Will a 2 A stepper give any more torque than the stock one (I know it is rated at a higher oz-in but does that actually translate to more torque)?
Finally, where are the specs for the Ender 3 stepper drivers listed?
