      Could you please tell us what is terrible with your prints? Wrong dimensions, warping, ... Is it the printbed problem of the other thread?

      If you setup your stepper motion and extruder motion the same as for the ramps, the print should be similar in my understanding, if you didn't change the hardware.

        I'd be glad to help if I can but I need a bit more to go on than the fact that prints are coming out worse than ramps. I can let you have all my configuration files but as mine is a CoreXYUV (for homing) and has five extruders, it might be a bit complex and lead to further confusion. I'd be willing to take a bash at converting whatever the ramps config files are though.

        One statement that's just plain wrong is this

        "Guess this things sensitivity also means it need all high quality components and that is fair".

        Quite the opposite in fact as Duet firmware has the ability to compensate for all sorts of mechanical defects, and just about everything is configurable, but of course that does lead to extra complexity.

          The bed is fine

          • The extrusion is uneven and inconsistent

          • The BL-Touch has been a hassle and still is non consistent in its behavior

          • Layer adhesion problems

          • Problems with using my 12V fans (as I do need for the blower!)

          • The layerlines are very prominent

          • PID tuning problem - Warning??

          • Thermistor issues - Beta value?? Do we really need to calibrate this as well?

          • G29 S2/M561 Not clearing mesh? What is the difference and why do we have two options in the GUI??

          I think it goes on but this is what comes to mind

            That's a really great looking printer build. I'd love to see it running well on the Duet. If you change your mind and want to take another crack at it from a fresh start let me know. Answering questions on here is more of a hobby than a frustration. 😉

              I wait for the answer of the expert, but for BLTouch: I ordered one for me now, so here are my help links I found yesterday in preparing:

                I migrate from Marlin/Ramps to Duet and it was not easy. But the potential of macros and fully gcode based configuration is so vast that I can not even think of rolling back 😄

                There was a lot of things, like unload and load a new filament, that I find it very difficult to implement with Marlin and now it is just a very clever macro that even asks me to confirm the insertion of a the new filament. My printer is so silent (of course you can achieve that with better drivers with the Ramps) that sometimes I tough that there was some issue.

                Also the electronics and wiring does not look like a bad neighborhood in the Blade Runner universe like it was with my Ramps. 😄

                So... Finish your design and polish it. When you have time get the Duet again with more time to tweak it. When you get used o the configuration/macros things it will even feel (and be) much that recompile and rewrite your firmware every time you change something.

                  Its a shame someone can't help you iron out the issues, my corexy when I swapped to duet just worked better than ever. True it was my second board and I had a handle on it at that stage, but if we look at your points in detail:

                  The extrusion is uneven and inconsistent
                  What microstepping are you using and what extruder? What motor current (is it 75%-80% of the motor's rated current?)

                  The BL-Touch has been a hassle and still is non consistent in its behavior
                  That's BLtouch for you, but I have managed to run one for testing purposes from duetwifi without any apparent problems.

                  Layer adhesion problems
                  That has nothing to do with the firmware, unless you are under-extruding or the nozzle isn't staying the correct height above the bed - probably related to bltouch issue.

                  Problems with using my 12V fans (as I do need for the blower!)
                  I presume you are running the duet on 24v, fans and different voltages are a challenge and the range of 24v fans is much more limited. I was using 5v fans until it killed 2 duets and 2 paneldues from a wiring short - won't make that mistake again. Get a few buck converter modules, there are detailed instructions to use them to get 12v PWM's fans from 24v supply.

                  The layerlines are very prominent
                  Got me on that one... could be a million reasons.

                  PID tuning problem - Warning??
                  What warning?

                  Thermistor issues - Beta value?? Do we really need to calibrate this as well?
                  Well no, I'd dump thermistors and go to PT1000s absolutely the easiest way to measure temperatures, just plug them in, add the correct line in config.g and you get known, predictable, (near) linear response to temperature changes.
                  I have calibrated thermistors using k-type thermocouples and measured resistance at known temperatures then used online calculators to get the beta value - but PT1000's are the way forward.

                  G29 S2/M561 Not clearing mesh? What is the difference and why do we have two options in the GUI??

                  I run this macro to do a mesh:
                  M561 ;disable compensation
                  G1 X135 Y97 Z5 F2000 ;move to bed centre
                  G30 ;set Z=0 level
                  G1 Z5 ;lift nozzle
                  G29 ;grid compensation
                  G1 X140 Y100 Z50 F2000 ;centre head

                  Then load it in config.g with
                  G29 S1.

                  I suspect any mesh issue you have relates to the BLtouch - have you considered a slightly more accurate probe?

                  If I had more time on my hands and you were not too far from me I'd come and help you iron it out and take a look at your printer which looks very interesting.

                    Seems like a worms-nest... ☺

                    Well thanks for trying to help out. I guess I want something more plug and play like Marlin does for me an it is easy to configure without all kinds of special equipment and macros or what ever

                    I would never be able to support my customers in RRF configurations as it is now and with Marlin it would be easy

                    I just want something simple that works with the equipment and components I have and are used to

                    It sounds like I need more expensive equipment and what not to get this right and use a lot of time tuning it when I just want to print good prototypes as I do with the old setup and same components

                    You say the BL Touch is not good enough? Then this must be related to the Duet/RRF as it works as a charm in other configurations

                    Then I need a PT100 board? Well here we go - adding more stuff I dont have and ever needed printing from from PLA to Polycarbonate and up to 275c no problem

                    Sorry I just want something that works on the printers I am building and supplying to others as well

                    I guess in this time next year I might have changed my mind but the thing is that the flexibility of the firmware seems to be the bottleneck in my mind

                    Just wonder what all the fuzz was about and still dont get it except it is very quiet...!

                      I would say some of problems are due to the extruder (layer lines, extruding uneven, layer adhesion). So I would test and calibrate it first, then Z-leveling with BLTouch.

                      I changed to 24V also and bought 24V fans to avoid the dangers of wrong wiring, it costs only a few bucks. But there are forum threads for wiring 12 or 5 V here also.

                      One about 12 V fan:

                        @pro3d You can connect PT1000 or thermistor directly, only for PT100 or thermocouple you need additional boards.

                          @pro3d I hope BLTouch is good because I bought it 😉 Presicision is 0.01 mm, this should be enough precision. I bought it because it works with all print bed types, glass or anything else.

                            @joergs5 It used to be good before I converted to Duet. Now it seems like a bad probe...

                            I guess I just had to high expectations for this board and did not anticipate these problems I have run into and all the macro world I dont really like

                              @djdemond How do I attach a PT1000 to the heater block? Or do I need another heatblock? seems like they are 4mm?

                                  I also experience whining. I read about this on the trinamic 21xx but is this the same thing? They whine a lot I think. 24v 1200 mA

                                    One more thing I miss about this setup some camera solution. Seems like we need the rpi anyway or some wifi cam.

                                    Or what do people do for camera?

                                      I use a PiZeroW with camera module running MotionOS as an IP Cam. It works well for viewing, but no time lapse function.

                                      There is currently no solution as easy as that provided by Octoprint.

                                        @pro3d at certain microstep/current settings the Trinamic drivers have an audible whine when standing still (I have only experienced this when they are holding a position, not while moving). This is not unique to the Duet, but a "feature" of the drivers, however because we have SPI control of the drivers we have idle current reduction and standstill current reduction that drops the current by a configurable % when the stepper is stood still or moving very slowly. See:

                                        https://duet3d.dozuki.com/Wiki/Gcode#Section_M906_Set_motor_currents
                                        (the I parameter)

                                        This is the percentage of normal that the motor currents should be reduced to when the printer becomes idle but the motors have not been switched off. The default value is 30% and always be at least 100mA.

                                        https://duet3d.dozuki.com/Wiki/Gcode#Section_M917_Set_motor_standstill_current_reduction

                                        This command sets the percentage of the current set by M906 that is to be used when the motor is stationary but not idle, or moving very slowly.

                                            @pro3d Odd, all reports we have are that with the TMC 2660s the steppers are significantly quieter while actually moving. are you using interpolation to 256 microstepping? Something like

                                            M350 X16 Y16 Z16 E16 I1

                                            The interpolation is set by the "I1" but it only applies at 16 microstepping.
