    So I was kind of frustrated in my previous post not being able to print anything reasonable with the Duet after 100 hours of troubleshooting..

    tl;dr - It was all MAINLY due to a new Cura release during conversion and 3.4.0/3.4.1 does not work slicing a XYZ cube or other object - least not here...

    I converted back to Marlin on my old setup but I had IDENTICAL prints - the worst kind and picked everything apart and added new components to troubleshoot.

    Although I did find a stripped grub screw on the extruder motor gear so it might have slipped as this was moved on conversion - Fixing it did not help me printing on the Duet

    When you look at filament usage sliced with cura 331 and 341 you see MAJOR difference so it under-extrudes big time

    From Left - A: Marlin/MKS Gen 1.4/DRV8825/Cura 3.3.1 - B: Duet/RRF/TMC2660/Cura 3.3.1 - C : Duet/RRF/TMC2660/Cura 3.4.1 - D,F: Same as C but with RRF extension/wo

    Sorry about my behavior and letting my frustration go towards the Duet setup

    Here you can see some cubes sliced/uploaded and sliced/printed with DRRF Extension

      These are all printed NO layerfan so dont mind the hot corners ( Yeah I burned my fans when installing the Duet... 12v fans dont like 24V)

        Hooray, I'm glad you got things sorted, the duet is a fantastic board, as for your fans there's plenty of posts regarding hooking 12v fans up to a 24v system. Basically you can use a buck converter to go from 24v to 12v and feed that into either the middle pin of the fan selector jumper or into the + lead on a fan, as long as you're connecting the - to the fan connector of your choice your fans will work.

          I have the fan thing sorted out but waiting for new fans

          There still are some issues though as the Marlin config still prints better than the Duet but I have to calibrate some more

          Left Ramps/Marlin - Right Duet/RRF
          All no layerfans - Not sure what is going on with the right one but why are te corners so bad?

            I am not expert, but with both Cura setups being the same, you may want to look inside config.g to change the motor current or acceleration values. I use S3D to slice and get decent corners with layer fans on

              I run same accel/jerk as on the Ramps as is 2000/20 (mm/s^2:mms)

              Might be a temp issue? I only have a NTC3950 100K so it might give some deviation in the temp

                My guess is that the temperature was too high on the right hand print. What M305 H1 setting are you using in config.g?

                Also be aware that jerk in the M566 command is measured in mm/min like all other speeds. So you should use 1200 if you want to use the same 20mm/sec value as you did in Marlin.

                  Thanks for the response. I do know the conversion from mm/min to mm/s so that has been taken care of.

                    I do have some experience with TMC drivers before not able to handle this high accel but that was 2130 so these 2660 should be stronger?

                    Should I drop interpolation?

                        Oh I just measured the resistance after warming the thermistor in the oven. Not good?

                          That depends on how accurate your oven thermostat is! Also, if it isn't a fan oven, the temperature will be very different between top and bottom.

                          The Marlin table for that thermistor probably assumes B=3950 (incorrectly) over the entire temperature range. So using B3950 in the M305 command may give you more similar results to Marlin at the same indicated temperature.

                            I changed the M305 and printed new cubes. Something is not as it should be and I dont understand that it is all due to temperature as it shoudl be ok in a 20c temp span (190-210)

                            I also now tried different driver modes
                            A : 1/16 I1- M566 X1200 Y1200 - M201 X2000 Y2000
                            B : 1/16 I0 - ...
                            C : 1/16 I1 S2 - ...
                            D : A: 1/16 I1 - M566 X600 Y600 - M201 X1000 Y1000

                            Here are some cubes with the benchmark in the middle

                                I have tried ranges from 190-210 and it does not extrude much lower

                                I also now tried 1/32 stepping on XY as that is what I have on the Ramps but it was the same result. I will try one slower

                                  It really does look to me like a problem of extruding at too high a temperature without cooling. Have you checked how low you can set the temperature and still extrude when using the Duet? Bear in mind that the Duet may be displaying higher temperatures than your RAMPS did for a given actual temperature, because you are using a different thermistor configuration.

                                    +1 Looks like the temp is too hot. Have you tried running a temp tower with your duet setup?

                                      No temp tower - I just try to replicate what I do with the ramps controller

                                      I just now check minimum extrusion temp - 190 is ok, 185 it skips

                                          It should be yes - It is not the motor that skips but the filament starts grinding
