The initial draft for community-created BIBO2 vendor bundle.
This copies the Draft configuration bundle created from information in #3560 and currently hosted in my Github. https://github.com/photodude/BIBO2-PrusaSlicer

Known issues with the current draft 0.0.1-beta2.

  • z-seam blobs and pits
    • blobs at the z-seam is still an issue.
  • Bed model for ditto printing has an offset issue See issue Offset Print area origin doesn't match with custom bed model origin. #3798
    • bed model is currently commented out and there is no custom bed texture for the ditto printing options. (ditto printing aka copy printing or duplicate printing with multi-nozzle printers. Bed size in the x-axis is restricted to the distance between nozzles.)
  • Not all materials in the configuration bundle have been tested
    • I don't have TPU or flexible filaments, PETG, ABS, or PVA/HIPS dissolvable supports, to test with. Settings are drawn from those reported in the BIBO facebook group and the Prusa and Creality vendor profiles. No reports from the community have come back to verify testing with the settings at the time of this PR
  • Reported issue with start gcode being too long for printing over USB drives causing printers to stall on start gcode
    • I personally consider this one something that can't be addressed and is likely a limitation of the TFT28 screen and MKSgenL mainboard. Some simplification of the start and end gcode is still possible.

Additional known issues which are related to specific hardware not stock hardware. the configuration bundle is focused on stock printers.

  • reported issue with start gcode causing the filament to unload
    • I haven't been able to replicate this and the solution to remove use_relative_e_distances proposed by the user reporting the issue breaks the wipe tower functionality. The wipe tower requiring use_relative_e_distances is mostly only an issue with the dual extrusion profile; but currently, all printers are set to use_relative_e_distances. Sub-note, The user reporting this issue has a modified printer with a 32-bit mainboard.

Reported issue with start gcode causing extruder crash on systems with 32bit mainboard and sensorless homing.
This is a non-stock system and I can not replicate the specific issue as I have a stock printer.

Tagging those who have requested this PR @mikolaszuza, @bubnikv

Sorry, something went wrong.

Although the "present print" code works, it really seems more like a gimick than a useful tool. removed to simplify end gcode.

Thank you! I made pull request on your github repository where I removed unnecessary (I believe) printer models. This way only one printer will be visible in configuration wizard (BIBO2 Touch) but other printer variants (E1 only, E2 only, etc.) will be still installed and available for users.

I have a lead on reducing the Z-seam blobs. The suggestion has come in from Steve Blackmore on the facebook group that reducing the deretraction speed to 25-50% of the retraction speed goes a long way in fixing the z-seam blobs.

That brings up a question if deretraction uses the retraction acceleration and jerk or the extrusion acceleration and jerk?

If deretraction is using the extrusion acceleration and jerk that may be compounding the blobing as the extrusion acceleration and jerk are much higher than the retraction acceleration and jerk

machine_max_acceleration_extruding = 5000
machine_max_acceleration_retracting = 1100
machine_max_feedrate_e = 20
machine_max_jerk_e = 5

I'll be doing some testing today with some of these settings
