I have had my v6 for less than a week and it isn't really any better than my crappy j-head clone I got with my Prusa i3 kit. I thought the E3D v6 was supposed to get a respectable print speed? Am I wrong. It works 100% fine at around 30mm/s print speeds in slic3r, but as soon as I crank up the speed to 100mm/s and print something with lots of infill it just clogs up and bends at the extruder as well as inside the bowden tube. I am pretty certain it has something to do with excess pressure building up in the hotend. I have searched and searched these forums and the web to try and find the maximum print speed for a v6 and I just can't. My setup is a 1.75mm ABS bowden setup, that is fed with a wades extruder, I am retracting only 4mm when needed. My E max feedrate is 15mm/s. My PID settings respectively are 35.71, 5.14, 62.02. I am using a non-E3D thermistor as mine broke during installation. (set to 1 in Marlin) (my supplier could not identify my the thermistor) (EDIT I have done some hunting to try and figure out what the thermistor actually is, and I have found that it is table 71 in marlin so I'll give that a go tomorrow and post it here) I am relatively new to the 3D printing game, so please could some one help me with this? Here are some things I have tried: Increasing the temperature from 240C to 260C. Decreasing E steps/mm. Re-leveling bed (fixed it for about two more layers than normal). Auto-tuning my PID settings several times. please ask if I need to provide more info, and please tell if there is something I can do.
