Final calibrations for RostockMax V3.2



  • I have already found a lot of help here with troubleshooting my printer. There are some
    issues I am still having trouble with, for example printing from the SD card inserted in the LCD. Thanks to helpful comments on a previous topic, i managed to connect my printer to access point mode. There is M375 and Z probe trigger errors when trying to start up bed mapping. My files:
    homedelta.g:
    M203 Z25000
    G91 ; use relative positioning
    G1 S1 X750 Y750 Z750 F5000 ; move all carriages up, stopping at the endstops
    G1 S2 X-5 Y-5 Z-5 F500 ; move all towers down 5mm
    G1 S1 X8 Y8 Z8 F500 ; move towers slowly up 8mm, stopping at the endstops
    G1 S2 X-5 Y-5 Z-5 F500 ; move carriages down 5mm
    G90 ; back to absolute positioning

    I was also wondering how to update my panelDue's firmware. Thanks!



  • Additionally, when i just started it up, i got an Error M375: height map file heightmap.csv not found.

    Have you used G29 to create a heightmap yet?

    https://duet3d.dozuki.com/Wiki/PanelDue See here for the PanelDue firmware.



  • @Phaedrux
    no, i haven't done that yet. I thought commenting out M375 would make the error stop showing up for now. Thanks for the firmware update. Should i go ahead and put g29 in my config.g?

    @insertcoin said in Final calibrations for RostockMax V3.2:

    Should i go ahead and put g29 in my config.g?

    No. G29 will run a probing routine of the bed surface as defined by the grid setup by M557. It won't run from config.g because it hasn't been homed yet.

    You would either have it run once, and then load the saved heightmap (such as with M375) or you would run it before every print. It would depend on your needs. For a delta, proper calibration is critical, and if the bed surface is flat glass, you likely don't need to run G29 at all.
