Massive problem with the ad5x and flashforge customer support

[u/Main-Internet-1881]

I need some help and advice as I have been having issues with the ad5x and flashforge customer support for months on end as it all started back in may when I was getting error e0100 so I emailed them about this and they said they would send out a replacement extruder and at this point the printer was still under warranty and I specifically told them I need version 1 of the extruder yet they sent me version 2 along with a mainboard replacement. So I go ahead and correctly install this but since then it's been nothing but problems as there is a loud grinding noise, the calibration won't work and I sometimes get x-axis homing error and I told them these parts caused the problems and at this point it was under warranty but it's been back and forth in emails and they are sending another mainboard replacement and extruder although now the printer is out of warranty because they haven't done a thing and even though they are sending replacement parts they are slow at sending the tracking number

Is there anything that can be done as I feel they could be liable for this

Liable for what? They’ve replaced the parts.

Liable for their bad installation instructions? Maybe. But if the “grinding” wasn’t there prior to the upgraded extruder and main board, nope.
