What am I doing wrong?

  • 3D Printer Model: Test towers
  • Slicer: Cura
  • Hardware Setup: Tina2, Quantum3d PVB Black
  • Problem description: The bridges are just not working. I don’t think it is technically stringing, but is definitely stringy. Not even sure what the proper search terms are to find help. please see photos.
  • What I tried: Printed a full set of test towers to try and figure out what I am doing wrong.

I am very new to this, hoping its something obvious and easy to fix.


The first thing would be to ensure that the printer is properly calibrated; extruder stepper steps, flow, retraction… and then, set appropiate parameters on the slicer of prefference before printing (I advice you to use OrcaSlicer !); printing temperature, printing speed, cooling.

I was under the impression that the calibration process is derived from the outcome of the test towers prints.

How do I calibrate these values when I can’t complete the test towers?

Great advice! Calibration is definitely the foundation for good prints.
