Z probe 0 not found after upgrading to Firmware v3.2 from v3.1.1



  • I upgraded to firmware 3.2 from 3.1.1 today and now my printer will not home the Z axis. Before the upgrade, everything worked fine. I'm sure that it is a configuration issue; as I had to change a lot of my configuration syntax when updating from firmware version 2 to 3. I don't understand why the config formatting has to change between firmware versions to the point that it breaks things?

    I am using a BL Touch as my z probe. The error that I am receiving is below. I will upload my config.g, homez.g, and homeall.g for your review. I ran the M98 P"config.g" command in terminal, as was suggested by another post with this error. The printer returned that there is in an invalid P parameter in my config, but it does not say which line that invalid parameter is on. Please let me know if you need any additional information. I appreciate your help!

    M558 P9 F300            ; speed up homing probe
    G30                     ; home Z by probing the bed
    M558 P9 F120            ; slow down homing probe for second pass
    G30                     ; home Z by probing the bed
    

    Remove the P9 from the M558 commands in your homeall

    Is that from you running M98 P"config.g" or from trying to home?



  • @Phaedrux The errors are from trying to home all and home z.

    In that case I am sure the P9 is the problem. Reboot the printer after you remove the P9 and try homing again.

    M98 P"config.g"

    That fixed it! Thanks a lot! Was that a change from v3.1.1 to 3.2?

    Also, I am still receiving the following error. It doesn't seem to affect anything because OctoPrint just ignores it, but can you tell from my config.g what is wrong? Is there a way to output the line number that the error is referencing?

    Hmm. I wonder which P parameter it means... I can't see anything obvious from your config at a glance.

    You could try adding some echos to the config.g at various places before any commands with P parameters. M117 with numbers to try and identify where it's happening would probably echo when you use M98 P"config.g"



  • M350 X128 Y128 Z128 E16 I0 ; configure microstepping without interpolation

    this puts unnecessary load on the cpu.
    unless you have a specific reason, its better to go with x16 and interpolation.



  • @Phaedrux @jsn0327
    This line gives the invalid use of P parameter error

    M574 Z1 S2 P"zstop"
    

    Remove that line
