Hello everyone, I do not understand what happens with my HOTEND, this one does not want to extrude at a speed faster than 5mm / second. At first I thought it was my original extruder which was defective indeed this one came with a TEVO LITTLE MONSTER. So I decided to buy an extruder of the same brand that my HOTEND which I want to report it has nothing yet print at all, it is an ED3 V6 in 24V. I buy an extruder from the same brand. But I am unable to print with all this material if I extrude my filament faster than 5mm / Second, this one literally finds crushing. I try everything I have repeated several times the hotend, I manage to pass the filament by hand at a temperature of 210 °. For the extruder, I have to disassemble this one also several times. Everything is well up no force. I know that one must play on the tension screw of the spring to exert more or less pressure on the filament but nothing does. I really do not know what to do I think I will order a hotend among the Chinese because the one I have on my BLACK WIDOW works really well. I find this really a shame because at the price or is the hardware at ED3 this one should work better than that. If you have an idea I am listening to you. Thanks in advance.
