Delta semi-automatic calibration (M558 P0) along X axis instead of Z

  • I'm using delta printer without z-probe. I used to use semi-automatic calibration many times before (using DWC, where popup with up-down controls for Z axis shown). Today I replaced hotend heater block and decided to re-calibrate printer, but I ran into an incomprehensible problem - instead of up/down (Z axis) controls DWC shows me controls for X axis:

    Adjust height until the nozzle just touches the bed, then press OK
    Use the following controls to adjust X:

    Seems like I should change something in configs after upgrading to firmware version 1.19, but I don't understand where I'm wrong.

    Current firmware version is:

    Firmware Electronics: 	Duet WiFi 1.0
    Firmware Version: 	1.19 (2017-08-14)

    I think you are using incompatible versions of DWC and RRF. Use a more recent version of RRF or an older version of DWC.

  • It seems for me that I'm using latest available release version:

    But anyway I will try to re-upload & update, thank you.

  • Upgrading to latest stable firmware files that available on github (1.19) did not fix this issue.

    But latest edge version is working OK (1.20beta10). I hope beta10 stable enough for production printing 🙂

    Thank you!

  • administrators

    Latest stable firmware uis 1.19,2, not 1.19. See

    There have been reports of some layer shift issues with 1.20beta10. I haven't been able to reproduce these yet.

  • Oh… thank you again. I thought that latest version is available here:

    I did not think of looking at the releases page at github at

    I will try to downgrade back to 1.19.2.

  • administrators

    Yes, I need to remove the "Stable" folders, because stable versions are now released using the Github Release mechanism.

  • @dc42:

    Yes, I need to remove the "Stable" folders

    By the way, this was useful for those who know about [c]git pull[/c] command. I'm one of those who used this command - just two words to get latest available firmware, readmes and source code together. But I agree that releases page is more appropriate place for binary files.
