[BUG]: Probe failing only with Bed Level Visualizer plugin enabled

[jordansilva]

Describe the bug I tried several times to update the bed level with bed level plugin visualizer enabled, by calling G29 T myself or calling the script via plugin using octoprint. Every time that I had the plugin enabled or tried via plugin I had a consistent Probe failure at the same point. G29 T worked every time I had Bed Visualizer Plugin disabled.

I never had any issue before using the plugin. The issue started after I updated all my plugins and OctoPrint to 1.9.2.

Expected behavior To run the probe without failure.

Debug Log octoprint.log serial.log

M117 Homing all axes ; send message to printer display
G28 ; home all axes
M420 S0 ; Turning off bed leveling while probing, if firmware is set
; to restore after probing
M117 Creating the bed mesh levels ; send message to printer display
@BEDLEVELVISUALIZER ; tell the plugin to watch for reported mesh
G29 T ; run bilinear probing
M500 ; store mesh in EEPROM
M300 S440 P200 ; make calibration completed tones
M300 S660 P250
M300 S880 P300

Try it without the T on the G29 T line so that it's just G29. There's nothing in your serial.log that indicates a failure of any kind, it just never completes.

I found this article that covers a couple of possible reasons for probing failed error, I would focus on the options that don't require Marlin firmware changes as it seemed to have worked for you previously. One that stands out is where the screws are out of a wack so much that distance traveled is causing a failed probe point.

I have checked this article as well, and also tried G29 but no luck. It was consistently failing at 6/49 (front right).

I just reconnected every cable and raised up the side that was failing. Apparently it worked now. Checking the bed level I noticed my x axis is the one that was really messed up, so probably the issue was related to my X axis was crooked.

Thanks for the assistance, nothing related with the plugin. Thanks for the plugin :)
