Bltouch correct homing, but problem while printing

[Amazon62]

Hi,

Nice to meet you all. Since a year I've been printing with an Ender 5 machine with great joy and good prints. Now I upgraded the machine with a V4.2.7 silent board + th3d software and a bltouch. All good, except for the bltouch. I calibrated the probe and it homes on the desired height of the nozzle to the bed, but when I start printing, the nozzle hits the bed. I searched the internet for solutions, but I couldn't find a pleasing answer. Could anyone help me out? I have used the end-stop connector, not the 5 pin.

Thanks in advance!

Hi, @Amazon62 According to your description, it may be caused by high compensation value, please according to the video tutorial on leveling to adjust the compensation value.

You can remove the limit switch used before, and the wiring of BL-touch is shown below.
