    Hello all,

    I have a delta Kossel clone running a Titan extruder to a Bowden V6 hotend that is consistently grinding filament even when extruding at 5mm/sec. It had been working flawlessly for over a year, right up until I moved it from one room in the house to another. I didn't change anything at all, which is why this is so baffling.

    My current setup is:

    - E3d V6 hotend with genuine nozzles
    - Titan extruder with the a big (not pancake) motor
    - Duet Wifi brain
    - 12V power supply
    - Nozzle is 0.4mm
    - PLA filament is is a perfect 1.75mm when measured with calipers
    - 700 mm long PTFE Bowden tube
    - Cooling fan directly attached to hotend runs as long as power is on

    Steps to reproduce: extrude 100mm of filament at 5mm/sec or more in the Duet Wifi web console.

    At this point I've tried everything I can think of:

    - Replace filament
    - Clean nozzle with probe
    - Clean nozzle with cleaning filament
    - Replace nozzle with a new E3d 0.4mm one
    - Replace Bowden tube with new one
    - Disassemble and clean the extruder
    - Move extruder to new positions on top of the frame
    - Reseat extruder motor cable
    - Run different PLA filament
    - Reassemble hotend according to E3d instructions

    If anyone has any other ideas, I'd love to hear them. Thanks in advance for all your troubleshooting wisdom.
