      So I went to the my first print and I chose the Cube.
      https://www.thingiverse.com/thing:1278865/files

      I am using Cura 3.5.0 for the slicer. It seemed to start out great but then thing went horribly wrong.

      The first few layers look correct then it just started shifting. Then is just decided to move to a different location and print.

      Here are my Cura settings for the printer that I added:

      I am so close I can taste it. Any idea what I am doing wrong.

        Looks like severe under-extrusion to me. Did you calibrate your extruder?

          How do calibrate it? I can't find any instructions

            Not to sound too snarky, but "How to calibrate 3D printer extruder" turns up a lot of hits in any decent search engine, include a somewhat dated video... Basically: Disconnect from hotend, mark/cut filament, extrude some arbitrary length and measure what actually was extruded. Use the difference to adjust the M92 E setting.

              Yah. I was looking at the duet page and didn't find it. Googling I did find it. I am calibrating it now. Figured out why the print shifted. For some reason the gear screws on the X & Y motors came loose and it was slipping.

                @twistedfab13 Apparently the page linked from https://duet3d.dozuki.com/Wiki/Step_by_step_guide#Section_Initial_configuration still needs to be written

                  Well the print looks 100% better. Still have a little adhesion issue at the half way mark. But the size is about spot on.

                    I'm not convinced these are adhesion issues - still looks like under-extrusion to me. The first third of the cube does look good though. Make sure that the extruder motor is not skipping steps and that the nozzle is not getting clogged. Also, check that the printer is able to pull the filament - I got similar issues one day when the filament spool was blocked and the extruder motor too weak to pull the filament from the spool.

                      @twistedfab13 Stepper skipping steps/grinding filament? Which filament do you use and at which temp? Speed and layer height?

                        I wrote this as reply to a similar thread last week.

                          I did the extruder calibration and once calibrated it seemed to be dead on.

                          Hatchbox 1.75 PLA

                          From Cura:
                          Printing Temperature 200
                          Printing Temperature Initial Layer 200
                          Initial Printing Temperature 190
                          Final Printing Temperature 185

                          Printing a temperature tower to check the temps for this new roll of PLA.

                            The temp I had it seemed to be too low. Tower at temp 205 and below fell apart. 210-220 worked the best with 220 being the cleanest.
