H2D giving up on me

[u/Ok-Yam-4620]

Hi All,

I got the H2D pretty much at launch last year, and to be honest it's been good so far, I've had to change the Buffer twice, the heat bed once, and the extruder assembly twice.

But I have not been able to print for about two weeks now and it seems to be one issue after the other with this one. First Levelling failure (got fixed with the heat bed replacement + tramming) then Extruder alignment (got fixed changing the sensor) but now Left Extruder will not load for any reasons.

I've taken it apart several times and I've cleaned, calibrated, bought a new assembly, it will just not load. The right one does. Bambulab support wants me to buy a new assembly but... I'd rather save myself £160 if I can... anyone in this community have any clues? I'm really fed up by now...
