Duet 2 latest firmware



  • Hi,

    i dont connect to forums time ago...

    i have instaled

    Board: Duet WiFi 1.02
    Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 2.04RC4 (2019-10--9b1)
    Duet WiFi Server Version: 1.23

    with the crisis of Coronavirus, now I am more at home ... that I can dedicate to the printer ...

    The issue is, the first thing I want is to update the firmware, since I haven't touched it in a while.

    The current one, I think it is 2.05.1, but I am not sure, because I have read that there is a version, beta, 3.xx.

    What firmware do you recommend installing?

    Another thing is to adjust / configure my Zprobe, a Precision Piezo.
    In 95% of the points, its operation is correct, but in that 5% it usually fails, detecting false positives

    I have it config.g

    ; Z-Probe
    M558 P8 I1 R0.9 F150 Z1; set Z probe type to effector and the dive height + speeds
    G31 P500 X0 Y0 Z2.5; set Z probe trigger value, offset and trigger height



  • 2.05.1 is the latest of the version 2 of the firmware.

    version 3 brings more features, and is availbale as 3.0 release and newer release candidates - unless you specifically need features offered by RRF3 I'd go with 2.05.1 as the configuration changes to RRF3 can be non-trivial and there are imo still a few kinks to iron out of RRF3.

    as always read the whats new files before updating.



  • If you are getting too many false positive on the piezo you could try to back off the sensitivity resistor a bit. Be careful, that little potentiometer is fragile.

    With the old kind with a separate piezo element it is a bit of an art to tighten the screws to get the right squeeze on the piezo. The Orion is a lot easier to use.

    The Z parameter to G31 looks way off. For a probe that senses with the nozzle it should be very close to 0 (zero). I run with Z-0.1.

    And the Precision Piezo likes fairly high probing speed. I use F600 for M558.

    Thanks, for the moment rest in version 2.... i have updated to 2.05.01.
    Do you know if support for version 2, will be dropped?



  • @bondus

    Thanks too,

    for the moment its working, no false positives. Now i have:

    ; Z-Probe
    M558 P8 I1 R0.9 F600 Z1; set Z probe type to effector and the dive height + speeds
    G31 P500 X0 Y0 Z-0.1; set Z probe trigger value, offset and trigger height
    

    The results

    COMPENSATION

    Number of points: 25
    Probing radius: 75 mm
    Probe area: 176.7 cm²
    Maximum deviations: -0.352 / 0.138 mm
    Mean error: -0.060 mm

    The bulk of development going forward will be on RRF3. RRF2 may get some bug fixes if anything big comes up, but no new features.

    For the time being, it's probably best to stick with 2.05.1
