After a some time setting up the exhaust system, I have finally started to use my Glowforge Basic a couple of days ago. Unfortunately, it soon became clear that something about the gantry was off.
In brief, when printing even basic shapes such as squares, the left side of the gantry seem to get stuck when moving backwards (see attachments).
This of course leads to very low quality printings for more complex designs. I have tried all the alignments / perfect squares troubleshoots, thoroughly checked the rails for detritus and gently placed the head under the lid camera (as suggested in several related forums). Unfortunately nothing seems to work.
Is there anything I am missing? Any suggestions about how to fix this?
