Error: Z probe was not triggered during probing move



  • Anycubic Kossel Linear Plus w/ Duet2 WiFi, Smart Effector, 288.15mm Hayden Magnetic Rods, E3D V6 hotend w/0.4mm Nozzle X.

    Got it all put together and things are working.... For the most part...

    After installing the hotend to the smart effector, I've tried running auto calibration after doing the PID tuning and setting the Z0 value via these instructions. When the probe gets to the section of the bed furthest away from the Z rail, I get this error message. So, I ran M564 S0 to disable axis limits and then moved the nozzle around to 5 points of the bed and ran G30 S-1. I got the following results:BedZHeight.PNG

    My bed.g:

    The printer is physically level. I just can't figure out why, even with trying Mesh Leveling, the Z-Probe still doesn't hit those southern points. Any ideas on what I can try? Been without my printer for a good month or so while waiting on parts to come in and am itching to get back to it.



  • @beanman1 are all your endstops at the same distance from the bed?
    IIRC, they are on little blocks that are moveable so can be adjusted.



  • All 3 endstops are the same distance from the bed. That hasn't changed since I initially put the printer together in January.

    I did change from a glass build surface to a magnetic sheet though.

    I thought setting the the Z=0 via the G92 Z0 command would adjust for that. It seems to have worked just fine, for most of the bed, just not that southern edge.



  • Here's a quick clip showing the calibration being ran and the nozzle not touching the plate.

    https://www.dropbox.com/s/as5gpwd4cs6ipm8/Delta Calibration Fail.mp4?dl=0



  • @beanman1

    M208 Z0 S1

    M208 Z-5 S1 see if it hits the bed then



  • Seems to just be the Point 2 that's not touching the bed.

    Not sure what the M208 commands were for, but I tried them and no change.



  • @beanman1

    The 1st is from your config.g
    The second was to allow the nozzle below zero
    The M208 line should be negative as the smart effector needs to go negative zero to trigger
    So Z-5 is 5mm below zero as your showing -4.19 in your G29 diagram so it should have been able to touch the bed with -5mm
    You only needed to type M208 Z-5 S1 not both as the first sets the axis limit to 0 which is in your config this is mentioned in the Calibrating Delta printer documentation.



  • ok. Made the change to the config.g and Point 2 still fails to hit. It's not that the probe fails to trigger, it's the nozzle never goes down far enough. lol

    Point 40 of the Mesh Grid Compensation is where it stops when trying to run that.



  • Tried auto calibration again this morning and it's P1 of the bed.g that's not touching the bed. Here's the M122:

    Watching the nozzle move, it seems to actually raise as it moves from P0 to P1. There's more visible space between the bed and the nozzle as it goes to P1.

    This is getting frustrating as I don't know what to do and Google ain't helping much! LOL



  • @beanman1

    Can you type G29 S2 then calibrate ?
    Also set your height to H400 in config.g M665 line

    Yeah M208 is telling it can go -5mm it still has to hit it to trigger
    Delete or rename your heightmap so it can't load before you calibrate



  • @Carlo
    Also add ; before M501 in config.g at the end so ;M501
    And rename config_override to Konfig_override.g
