      Hi,

      I put this question here because I have no idea what is due, I explain the problem:

      • Delta printer
      • PETG
      • Printing speed 45 mm / s
      • Temperatures: 240/75
      • Layer height: 0.15 mm

      The problem occurs after the first layers, never at the same height, many times, only occurs once in the entire model, sometimes occurs, 2 or 3 times.

      What happens is that the layers move, maybe 1 mm, at most 2, the first few times I pass, I thought it was because the straps of the towers were not tense, and I tensed, the same thing happened to me again . Then I thought they were very tense ... and loosen them, but nothing. The same.

      The only thing that occurs to me at some point, the engine of a tower loses steps ... but is there any way to check this?

      I am using thiese currents in config.g:

      M906 X1200 Y1200 Z1200 E800 I40

      How do you see them?

      Two main doubts:

      How can I check if some engine is losing steps?
      What are the recommended currents for Nema 17 motors?

      P.D .: I take this post to congratulate Christmas to all .... Even David. XD.
      MERRY CHRISTMAS!!!!!!!!!!!!.
      Let's see if Santa Klaus brings you an OLSSON RUBY

        You could configure stall detection to report any stalls.

        Current should be set around 85% of the motors rated max current.

        Is the plastic curling and getting caught on the nozzle? Maybe you need to add some Z hop.

          Which Duet are you using, and what is the specification of the motors?

              there are many different nema 17 motors. each with their own current rating.
              also is it a duet wifi/ethernet/maestro.

              are you using 12v or 24v?

                  @peirof Since you're using PETG, is the nozzle leaving blobs behind? The blobs left behind would cause skips when they got left behind and when I upgraded to the silicon socks on my e3dv6, the blobs disappeared.
