Zaribo / Prusa i3 MK3s - Duet 2 WiFi - RRF 3.11



  • Zaribo/Prusa i3 MK3s - Duet 2 WiFi - RRF 3.11

    This is a dump from my GitHub. I figured people in search of doing similar to their i3 MK3s might have a better chance finding it here.

    ! Wiring guide: Duet2-compressed.pdf
    ! Always look here for latest revisions of all code and settings: My GitHub

    Hardware changes from stock MK3s:

    Note: The config.g file contains notes to facilitate easy adaptation to stock Prusa MK3s.

    • Bondtech Mosquito Extruder

    • 0.9 Stepper motors on X & Y axis

    • Duet WiFi

    • Zaribo 10mm Upgrade

    • PanelDue 5i

    • PT1000 hotend thermistor

    • BLTouch v3.1

    ⁉What do those hardware changes mean for your config?

    🔧Motors, microstepping resolution, and steps/mm.
    Unless you have the same setup as referenced above, you may have to change the microstepping resolution and the steps per millimeter located in the 'config.g' file. To retrieve your current machine's configuration, issue a M503 command in the terminal connected to the running printer. Pay attention to the microstepping assigned to the axis as that can change your steps per millimeter. Read through the /sys/config.g file comments and make the applicable changes as needed. More about this can be read here: https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors, here: https://www.linearmotiontips.com/microstepping-basics/, and here: https://blog.prusaprinters.org/calculator3416/.

    ⚠Once you have changed/verified the motor settings, review the networking top portion of the file. When completed, copy all the files located in the 'sys', 'macros', and 'filaments' directory over to your sd-card. The 'www' and 'gcode' folder are present in the repository for reference and should not be needed to copy over to the sd-card in normal circumstances. More can be read about sd-card here: https://duet3d.dozuki.com/Wiki/SDCard, more can be read about macros here: https://duet3d.dozuki.com/Wiki/Macros.

    🔧Sensorless Homing / Stallguard sensitivity.
    The TMC2660 drivers used on the Duet WiFi support the stallGuard feature. This feature allows the driver to detect motor stalls under some circumstances. Stall detection may be useful for detecting when a motor has skipped steps due to the nozzle hitting an obstruction, and for homing the printer without using endstop switches.
    As the given configuration files were authored while using 0.9 degree stepper motors on the X and Y axis, you may need to adjust your stallguard sensitivity and sensorless homing. For stallguard sensitivity, look for the "M915" in the current-sense-homing.g and current-sense-normal.g files. Read the full documentation here: https://duet3d.dozuki.com/Wiki/Stall_detection_and_sensorless_homing.

    💡Use the included Macros for filament handling.
    To make filament loading, unloading, and changing the most straightforward and simplistic possible evolution, I have made a macro set that is readily accessible from the PanelDue. To take full advantage of the duet filament system you will need to make the system filaments PLA, PETG, ABS, and PC. This will allow you to have custom instructions for each different filament, by adding such to the filament's config.g file. !Note: Based on my current macro version, it is required that each filament's load.g and unload.g remain empty. Placing code into these files will make these macro fail.
    "Set Filament Type" asks what type filament you are going to use; PLA, PETg, ABS, or PC. Based on the selection, this macro rewrites the "Heat Nozzle" macro to heat the nozzle for the selected filament type. !Note: This macro only has to be executed once for the given filament type change as it's settings are nonvolatile, regardless of reset or power off. !Note: The script will not let you change the filament type while filament is loaded.
    "Filament Handling" is for any filament unloading, loading, and changing regardless of the printer's state, printing or not. This macro will load, unload, and change filament based on two conditions; whether it detects filament is currently loaded or not, and if a print is in progress or not. !Note: The logic function in the macro retrieves the current status of the filament sensor to base the perceived desired action to enact. If your printer's filament is currently empty and you intend to load filament, please do not place it into the extruder until requested to do so by the macro. Else the macro will determine that filament is loaded and that you desire to unload filament, instead of load.
    "Heat Nozzle" is created by the "Set Filament Type" macro and can be selected to heat the hotend to the set temperature for the last chosen filament type. You do not need to run this to change filament, the "Filament Handling" macro automatically runs this macro to perform the heating of the hotend to carry out the filament handling, whether it be loading, unloading, or changing.

    Print flow events:

    When initiating a print, the following sequence of events occur in this order.
    /sys/start.g is the first codeset that starts at the beginning of each print. This contains the generic processes that apply to all filament types. From this codeset, the fillament's config.g is called.
    /filaments/PETG/config.g is the second codeset that get initiated from the "M703" command in the "start.g" file. As written in this example, we are set to use the PETG "config.g" file, located in the "filaments/PETG" directory. This contains the gcode commands that are particular to PETG filament type.
    Slicer's Start GCode is the last bit of codeset to be executed before the object's sliced gcode starts. This contains the settings particulr to the actual print and the exact PETG filament loaded. This would be your 'fine' settings, where PETG/config.g could be considered your 'medium' settings, and start.g would be the 'rough' - performing evaluations to get the printer ready.
    The part's actual gcode made by the slicer.
    Slicer's End GCode follows the printed object's gcode. This codeset lets the duet know that the print is finished which calls
    /sys/stop.g, the very last codeset that is executed. This last part commonly shutdowns heaters, retracts a bit of filament, and positions the machine to easily retrieve the printed part.

    Additional notes:

    💡Electrically independent Z motors: On printers, such as MK3, which uses two Z motors to raise/lower the bed or gantry, you can have the firmware probe the bed and adjust the motors individually to eliminate tilt. The auto calibration uses a least squares algorithm that minimises the sum of the height errors. The deviation before and expected deviation after calibration is reported. Run G32 to initiate the process. Read the full documentation here: https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors.

    💡PINDA v2: Pinda version 2 is upgraded from the previous version in that it now has an integrated thermistor, which this configuration electrically ties to thermistor E1 on the duet. Pinda temperature compensation has to be mitigated via g-code macro but will be handled via integrated function within the duet firmware shortly. Read @Argo's posting in the Duet forums: https://forum.duet3d.com/topic/16972/pinda-2-probe-with-temperature-compensation?_=1593546022132.

    💡BLTouch v3.1: The config.g has comment sections for using this probe and the wiring guide covers the electrical installation of the BLTouch v3.1 in the last few pages. Read the full documentation here: https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe

  • I added a new macro, Hotmesh.
    "Hotmesh" preforms bed a mesh probing routine with a heat stabilized bed. This macro will heat the bed based on the currently set system filament type, wait 5 minutes for the bed temperature to stabilize, and then perform mesh probe. Once initiated, the nozzle will rise to 150mm and then lower 15mm for every 30 seconds elapsed - about 5 minutes in total. Once the nozzle is at the bed, the mesh probing cycle will commence.

  • Latest README: README.pdf
    Latest sd-card dump: README above contains dump.
    Latest wiring guide: Duet2.pdf
    Archive file containing the full set of sd-card files, wiring guide, readme, and ideaMaker example profile set.

    The next meaningful revision of my files will most likely occur once variables are enabled within the gcode macros.

    If you find any issues or have any suggestions please let me know so I can take the appropriate actions and make this a better guide/code for the public.

    Many thanks Duet forum people!

    Thanks for the excellent reference examples.

    Also just a heads up it looks like the forum software or copy paste error is inserting some random {1} to your blocks.



  • @Phaedrux Thanks much!

    I saw the {1} and tried to get rid of them but for some reason, it didn't work.
    I did attach my dump-list.pdf so people could view it there also - I keep this one updated too.

    I'll give it a shot once I get some time this evening. Do you know what causes them?

    Cheers,
    Kolbi

    They seem to show up on line breaks within the code blocks for some reason. It's a forum issue.

    Ah! Just add a space after a line break and that gets rid of it.

    Good to know!

    not for all types of code interestingly enough, but haven't experimented with the complete list of language highlighting.
