In the past couple of weeks, my V6 hotend gets jammed very frequently. The nozzle is 0.4 mm and the printer is a D-Bot.
Here are some of the things I have tried so far,
- Switched between the original and a clone and both get jammed.
- Tried different heat breaks - the one where the Bowden PTFE tube goes all the way to the nozzle, the one where its an all metal one and the one that has a PTFE liner inside it.
- Checked and re-calibrated the E steps and the PID tuning for the nozzle.
- Used different filaments (PLA).
- Tightened the nozzle against the heat break every time
- Tried different printing speeds and also calibrated the extrusion multiplier.
- Tried different retraction speeds and lengths.
- Ensured that the heat sink is adequately cooled.
What could I be missing?
