Describe your issue:

My printer have started to get “BLTouch failed to verify sensor state”
When I start up the printer and then run home all, the probe works fine. When I start a print and the printer is ready to start printing, then theBL touch get this messatge.
I got I new BL touch to day, but I have the same result.
I hope you can help me.

Your klippy.log looks good. It looks like you’ve tried a number of different combinations of the options.

Two things:

  1. What is the make and model of the BLTouch that you’re using?

  2. Could you send pictures of how you wired the BLTouch to your Mini E3 V3?

The most likely cause of the problems is the wiring but if you have an obscure brand of BLTouch, that could require its own special configuration/tweaking.

The printer has working for 1½ years with klipper, the problem started around a month ago.
So the wireing is not the problem. Have used probe with no name on it for 4 years and go to day an 3D Touch V3.2, with the same problem.

That wasn’t explained above.

Now, I just took another look at your klippy.log. It looks like you upgraded your Klipper software (you’re running v0.13.0-154-g9346ad19) but you haven’t upgraded your MCU (it’s currently version v0.12.0-410-gcf3b0475).

I suggest you update your SKR Mini E3 V3’s firmware to the latest level and see if the problem with the BLTouch continues.

I have now upgraded the MCU
found this on Youtube

And have now mcu Version: v0.13.0-154-g9346ad19

I still got the “BLTouch failed to verify sensor state”
Run home all after and now the sensor works fine, but not when start printing.

In Orca slicer I have in “Printer settings” Machine G-code and Machine start G-code:
start_print BED_TEMP=[bed_temperature_initial_layer_single] EXTRUDER_TEMP=[nozzle_temperature_initial_layer] CHAMBER_TEMP=[chamber_temperature]

Under Material settings, and Filament start G-code:
; Filament gcode:
G90
G28
G92 E0
BED_MESH_PROFILE LOAD=default
M190 S80
G1 X10 Y10 Z10 F2000.0
M109 S244

I have removed the Filament start G-code from Material settings in Orca Slicer then it works, so the printer don’t liked the code…

Does any body have a nice G-code Filament start under Material settings?
Would like the purge line G1 X10 Y10 Z10 F2000.0
