BL-Touch works for Z home but not for bed leveling?

RomanVin · 13 Oct 2021, 16:16

The table leveling function has stopped working. The commands M280 P0 S90, M280 P0 S10, M401 and M402 are executed, the sensor works.

The table leveling function has stopped working

This implies it did work before. What has changed, if its the upgrade to 3.4b5, what firmware were you running before?

when you say it is working for Z homing, I presume you mean the BL touch deploys, triggers, Z home is set correctly as expected. What element of bed levelling is not working?

Please post your bed.g (using the </> option in the text formatting so its easier to read).

I didn't understand what happened.
I will clarify. The X Y axis moves as usual. When performing G29 or G32 probe does not extend. I returned to the RRF3.3 version, the initial config.g and all the files of the SYS folder with which everything worked. Didn't help, doesn't work as expected.

If you execute M401 (deploy probe) or M402 (retract probe) do they work?

Thanks.

@fcwilt The commands M280 P0 S90, M280 P0 S10, M401 and M402 are executed, the sensor works.

OK.

If you move the probe to the center of the bed, about 10mm above the bed, and issue a G30 does it work?

Thanks.

Yes, the G30 works.

Friends!
Found the problem. Together, everything turned out to be quite simple and complicated.
Simple - because in the harness from Duet2 to BLtouch there is a break in the probe control wire. Difficult - because I cut off the printer heads only in the zero position, floating fault. I could not even think that a new 3-wire cable could be defective. The printer hasn't really printed anything yet. Be careful with your choice of wires.
The topic is closed.

@romanvin thanks for letting us know what the issue was. glad its fixed.
