We just got two new TAZ 6’s last week. So excited!
One of them is working great. It’s been running basically non-stop since it came in. The other… not so great.
We’ve tried printing in PLA and ABS, sliced with both Cura and Simplify3D. We’re getting weird problems with bed adhesion. We’ve cleaned the bed sheet several times.
At first i thought it was just that the printer needed to be squared. The lower left corner of the plate was significantly lower than the rest of the plate, leading to poor adhesion on the lower left. Adhesion elsewhere was fine. This is what the feet on the bad printer looked like:

This was leading to the left front corner of the Y axis being elevated by over 2mm.
So, we loosened the brackets on the bad printer that connect the left-side 80/20 to the control box and lined up the feet.
Now adhesion there is better, but elsewhere it’s a problem. This is this morning’s print in PLA:
It’s the exact same gcode file that printed correctly, with no problems, on the other printer, so I know the file is fine.
I see a little bit of bubbling, etc., on the plate. Maybe that matters?
The auto-leveling seems to be behaving normally, but I’m really not sure what’s going on. Any ideas?
