Firmware 2.03beta2 available


  • administrators

    I've just released this at https://github.com/dc42/RepRapFirmware/releases/tag/2.03beta2. Highlights include:

    • Configurable endstop assignments
    • Configurable minimum speed
    • Fan speed is scaled by M106 X parameter
    • Leadscrew bed levelling bug that was introduced in firmware 2.03beta 1 is fixed

    I would particularly welcome feedback from users of CoreXY and similar printers. Please read the upgrade notes first.



  • @dc42 thank you ^^



  • I can confirm that Leadscrew bed leveling is fixed, thanks

    Leadscrew adjustments made: -0.008 0.016, points used 2, deviation before 0.009 after 0.000
    15:55:54M98 P"0:/macros/X Axis callibration"
    Leadscrew adjustments made: -0.088 -0.086, points used 2, deviation before 0.087 after 0.000

    That was quick!



  • @dc42 When I get a mo, I'll try this out and see if I can home my 3rd gantry. Could you expand on how to use the configurable end stop assignments please? The release notes say .....
    "M574 allows endstop input numbers to be configured (C parameter). Currently only the first input number specified for each axis is monitored."

    Can you expand on how to use this "C" parameter please - instructions haven't made it to the wiki yet.

    Here's an example of swapping the X and Y endstop inputs:

    M574 X1 S1 C1 ; X endstop is connected to input 1 which is labelled Y
    M574 Y1 S1 C0 ; Y endstop is connected to input 0 which is labelled X

    Thanks. One more question. I assume that if I go into the machine properties section of DWC, then in your example above, if I trigger the endstop for the X axis I would expect the Y axis switch to trigger. Correct? Or is the Machine Properties section of DWC clever enough to know that the switches have been re-mapped?


  • administrators

    The endstop states are passed to DWC after remapping, so DWC should read correctly.



  • Just did a quick print on my CoreXY. No obvious issues.



  • CoreXY - everything seems to working fine.



  • @dc42 Sorry to be a pain but for the purpose of re-mapping end stops, can I just ask if the following input assignments vs labels is correct?

    On the Duet Ethernet......

    Label "X" is input 0
    Label "Y" is input 1
    Label "Z" is input 2
    Label "E0" is input 3
    Label "E1" is input 4

    On the Duex 5.........

    Labels E2 to E6 are respectively inputs 5 to 9.

    Is that correct?

    Correct. Also inputs 10 and 11 are the two on the CONN_LCD connector. It's the same numbering as in the M591 command.



  • @dc42 Thanks. - I don't have any filament sensors so I've never looked at M591.

    May I suggest that this input numbering vs label be included in the Wiki somewhere. Either in the section entitled "connecting end stop switches" or in the section dealing with M574. I don't think I trust myself to edit the Wiki personally but I'll have a go if you like.


  • administrators

    Next time we revise the Duet we will number the endstop inputs and motor outputs, instead of giving them axis and extruder labels.

    Yes I believe you've said that before - makes perfect sense. Hindsight is always 20:20 ☺



  • Just want to report that this (firmware 2.03 beta2) is all working well for me. CoreXYUV is all doing what it should do. Also I have been able to get homing working on my 3rd gantry by temporarily assigning both drives and end stops to X and Y axes.

    The homing file is a bit complicated because basically I'm homing 7 axes - initially a course home, followed by a finer home at slower speed for each axis. Then re-mapping all drives and end stops so that for printing, it becomes a 3 axis machine.

    Anyway, big thanks to David.

    I have put it in with M574.

    Thanks - I'm sure others will appreciate that information.

    And for the sake of completeness I also added a table to Connecting endstop switches in the wiki.



  • @wilriker Very nice ☺
