          ok that looks good.

          now do the test again, grab the hotend carriage and turn on clockwise and anticlockwise between probes. dont force it but do it gently.

          after that do it again trying to rotate it forwards and backwards.

            in practice I take the trolley and manually try to move it and then I do the tests again, did I understand correctly?

              yes. we are looking for backlash in the assembly. movement could cause the assembly to rotate and cause the result you are seeing.

                  M906 X800 Y800 Z800 E800 I30 ; set motor currents (mA) and motor idle factor in per cent

                  there are default values from the configurator.

                  a quick google shows the motors seem to be 1,68 A motors

                  so you are running way to little current. try 1300

                      @Leblond said in Triangular wave and print area:

                      1.7 A

                      so running them at 75% rounding to nearest 100 is 1300.

                            I'm retrying cold-meshing the plate to see if we've made any improvements

                                  it seems to be very consistent.

                                  can you turn the glass 90 degrees?

                                    Is the X carriage on wheels?
                                    I'm not familiar with the printer and can't tell from the photos I've seen,
                                    Almost looks like an eccentric wheel causing the nozzle to rise & fall with each rotation

                                          level 3.png

                                          I've had the same problem once , it was the x axis wheels and stopped the ripple with linear rails , but I guess getting better would have fixed it too.

                                          Ender 5 plus linear rail and hemera powered by duet 2 wifi , CR10s pro v1 with bltouch mostly stock , BLV mgn Cube slowly being built powered by duet 3 mini 5+
