tool change macro issue

  • jag

    I am running RRF 3.0 on a Duet 2 Wifi.
    My setup has 2 extruders with a RC servo to lift the one that is not in use.
    Everything was working fine until yesterday. I was making a number of changes to the config file, nothing drastic. I think I just changed some of the settings for the extruder cooling fan.
    Now, when I attempt to change tools, the M280 commands in the tpre0 and tpre1 get stuck in the queue and nothing runs after that.
    The commands in the tpre macros are just:
    M280 P0 S110
    and
    M280 P1 S58

    I'm not sure what the extra code showing up in the queue is.
    If I run the M280 commands directly, I don't have any problem. The servo moves as commanded.
    Today I updated to the 3.0 release version. There was no change.
    Does anyone have any idea what is going on?

    This is a real long shot... I have seen a few oddities in R3 with toolchange macros solved by putting an M400 at the beginning of all the macros.

    Again, not a good fit for your exact symptom, but it is very quick to try.

    @Danal Thanks for the suggestion.
    For a minute, I thought it had fixed it. I turned the machine on this morning, added an M400 to the beginning of the two macros (tpre0 and tpre1) and it was working like a charm.
    Then I made some modifications to them (I made them call another macro that does the actual servo moves) but I left the M400 in (and added it to the other macros as well).
    It worked for a while, until a reboot and now it's all broken again.
    I changed it back to just the M400 and M280 P0 S110 and it still doesn't work.
    From looking at the queue in the M122 output, it looks like it is continuing to read past the EOF of the macro.
    There is some garbage in the queue that appears to be code from previous revisions of the macro.
    So, I tried putting an M99 at the end of the macro figuring that would make it exit even if it is ignoring the EOF.
    That unfortunately didn't fix it. The queue is still showing some gibberish after the gcode:
    Queued 'M280 P0 S58�D�M�>(��F��a��hgM6"��V�(�D'r�?�G�n$������~UT ' for move 7

    I can't figure out why it was working for a little while and now it isn't.

    Please check that the problem still occurs in 3.01beta1. Then post your config.g file and tool change files.

    @dc42 It does still occur with 3.01b1.
    Here are my config files and my tpre files.
    Let me know if I am missing something obvious.
    Thanks!

    config.g
    tpre0.g
    tpre1.g

    I realize this appears to be a flaw with the end of the tpre... nonetheless, may we see your tpost and tfree as well?

    And, even longer shot... M400 at beginning and end of each.

    Oh, and HUGELY long shot. Format a different SD and copy everything over.

    Tfree for both tools is empty (just comments at the top):

    ; tfree1.g
    ; called when tool 1 is freed
    ;
    ; generated by RepRapFirmware Configuration Tool v2 on Thu Jan 10 2019 13:50:44 GMT-0500 (EST)

    There is no tpost for either tool.
    I had been thinking of the SD card route. I just got a new SD card and tried it (I backed the old one up with tar and unpacked it onto the new card).
    Same deal.

    I just deleted the tfree files so that there are only tpre macros. Same behavior.
    I added M400 to the end of both the macros (after the M99 so it should theoretically be skipped anyway). No change.
    I added it before the M99, still the same.

    Interestingly, the selected tool does change in the web UI. If I attempt to move the machine (G0 Z100 for example), the machine does not move but the web UI location does change.

    I seem to have found a workaround. I'm not sure if it will continue to work.
    I changed the macro to have a relative move before and after the M280 servo command. Suddenly it started working.
    So, now my code is:

    M400
G91
G0 Z5 F4000
M280 P0 S110
G0 Z-5
M400
M99

    Nevermind. I made another change to the config.g (reduced the extruder cooling fan speed to make it quieter) and now it isn't working again.
    Strange...

    And interestingly, the symptoms in the output from M122 are different:
    Now it gets stuck with:

    It is currently working again. I'm not sure what happened. I thought the problem might have been that my homeall.g called my homez.g with an M98 with no quotes around the filename. I modified my homeall to not call the homez (and a few other tweaks) and everything suddenly started working. But, when I put the bad M98 back in (with no quotes, just to see if it would fail), I couldn't reproduce the problem.
