    Before my last upgrades, these configs are for Ender3 Pro which has a Bullseye duct and its BL Touch Mount, I am also running a Maestro board in my printer and using a PanelDue touch screen. All original hardware.

      Ok. So I printed a test cube yesterday. Usually when I printed something with the stock Ender 3 Pro board, the BLTouch would probe the bed before it starts to print, but not this time. The print looked decent, but a little squished in the layers. I need to experiment a bit here. BUT the strangest thing happened when the print finished. The extruder just stopped at the very last point in the very last layer and then the extruder retracted all filament from the nozzle and all the way back to the filament spool.

      I think this has to be related to Cura somehow. I’m going to try reprap flavor and some tunings found on this forum.

      This is a learning curve, but it’s fun to see progress.

          since a lot of people are converting their ender 3s it might make sense to include this as a default option in the configurator

            @Veti Those configs are for a stock Ender 3 Pro with a BL Touch mounted on these parts.

            I was still unsure of the thermistor params, but the ones in the config seemed to work OK.

                  Thanks again for sharing your configs. I noticed right away that the heated bed/nozzle did not get hot enough so I kept the stock config here.

                  M305 P1 T100000 B4138 R4700

                  I also changed the xy offset to match my bltouch mount because I don't have a bullseye. Even after that it still seems to probe on the outside. I bumped "Y" again and it is probing on the bed again.

                  I am running a test print again using Slic3r. Checked "Use relative E distances".

                    You'll need to check your start and end gcode in the slicer. It specifies what happens before and after the print. To home before printing there needs to be a G28. And to lift the nozzle after or at least move it away you can use G28 X to home the X axis to move it away from the print. You can get as fancy as you want.

                    The retracting all the filament thing happens when cura is set to use absolute extrusion and the end gcode tells it to retract a bit of filament but instead of retracting just a bit, it commands it to go all the way back to the very beginning of extrusion. Setting cura to use relative extrusion distances will solve that.

                      Thank you @phaedrux Slic3r stock with checked " Use relative E distances" solved it, but I really don't like Slic3r. I find Cura much easier to use.

                      I will look into how to use relative extrusion in Cura.

                        It's an option under the Special Modes menu heading. It might be hidden by default.

                            Now everything seems to be working like it was when using my stock Ender 3 Pro board.

                            Print quality is more or less the same, maybe a bit worse than before, but I need to experiment a little more with the duet config and in Cura.

                            But the stepper motor noise is almost gone they are so much quieter now!

                            I also had to lower the current for the stepper motors. They where running really hot using stock (x, y, z, e) (725, 725, 725, 900). Trying to find the magic numbers here.

                            I see everything from 400 to 900 on this forum.

                              The Ender 3 uses low current motors and 24V power, so I am not surprised that you need to reduce motor current. Stepper motor current is adjustable in steps of 100mA on the Duet WiFi/Ethernet, and 50mA on the Duet Maestro. So 600mA may be a good value to try, perhaps a little more on the extruder motor if necessary.

                                I've been using the following currents on my Ender 3 since I put the Duet wifi in it without issue.
                                M906 X950.00 Y950.00 Z850.00 E900.00 I30

                                I think the motors at their hottest hit mid 40C range so not hot for stepper motors.

                                  the ender 3 motors are
                                  x,y,z 0.84A
                                  e 1A

                                  950 might be a little bit hight for x and y.

                                    I guess I can try lowering the current. At some point I'm going to replace the X and Y stepper motors with 0.9 degree ones with more torque now that I'm using a direct drive extruder as well as glass with PEI on the bed.

                                        @veti you are right. I missed the 90% -_- thanks. My motors run extremely hot with what I already have so I will try with 600(x, y, z) and see.

                                          Haha so the 1000 mA I had set in my config mayyyyyy be toooo much is what you're trying to say 😂

                                          hmmmmm hahaha
