I teach at a University and we run a couple TAZ6 units for prototypes.
I have one with a dual extruder V3 and in recent weeks it has printed fine. However, last week and again to start this week, I have a student project that repeatedly fails (its striking me now that it could be JUST this one project - I should try something ELSE) - but anyway… As you face the machine the far right hand corner of the bed was like not printing -it was getting squished out bottoming out the print head.
I check Z offset Better but still not good.
Checked Horizontal runout on that arm and turned the Stepper a bit until the run was level.
And I’m wondering if my nozzle is open enough or what - the filament curls on the way out a bit.
Better - but NOW when the machine goes to move from the base layer to the next step - it sounds like its dragging again and eventually fails. I took some pics because you can see the surface finish on the base layer looks like it drags across - its all dull.
Thoughts? Do I need to look at the G Code on this?
I think for sure I need to try SOMETHING ELSE on that same machine and rule out that its not that student’s model.
I open to other input.!
