BLTouch not working

hsverre

THanks a lot

The photos of the wiring look correct, but if it's not getting power perhaps there is a break in the cable. I suggest doing a continuity test on your cables with a multimeter.

I havent dont a continuity test but i have replaced all of the wires and connected the bltouch directly on the bord. But, with the same result.

If you are absolutly shure a test will be a good idea i will do it. What cables are preferably the best to measure? Which of the cables are power to make it run the self-test when it gets power?

Can you send M122 and M98 P"config.g" and post the results?

connected the bltouch directly on the bord. But, with the same result.

Have you tried connecting this BLtouch to one of your other printers? Perhaps the BLTouch itself isn't working.
