### Basic Information: Printer Model: Ender 3v2 MCU / Printerboard:4.2.2 Host / SBC PI 3 [printer.cfg](https://klipper.discourse.group/uploads/short-url/lod6sQQROpOSEYZf6NiXdTHSTAp.cfg) (2.9 KB) klippy.log [klippy (4).log](https://klipper.discourse.group/uploads/short-url/bysgEWo3svMlMQJdGPDVdRpu8gh.log) (1.5 MB) …Hi , I setup up the parameter for screws\_tilt\_calculate. then i start the comand: it happens: Z goes to 50, printer moves to screw1 position, probe comes out, printer goes down, probe contacts and goes in, printer moves down until it stopps. I tried it with the command probe→ the same behavoir, then I tried in Z postion 200, the pin comes out, I touched it and it stops mms later. I just made it again with bed\_mesh\_calibrate. the same, it crashes into the bed… what is wrong? thx Dirk p.s. The Homing is working…. ---

Do you have a genuine BLtouch or a clone? If the latter one, you may read here: [BL-Touch - Klipper documentation](https://www.klipper3d.org/BLTouch.html#bl-touch-clones) ---

I now have the following settings: bltouch sensor\_pin: ^PB1 control\_pin: PB0 x\_offset: -42 y\_offset: -10 z\_offset: 0 # Note: You will set the z\_offset later via the web interface (PROBE\_CALIBRATE) probe\_with\_touch\_mode: True pin\_up\_touch\_mode\_reports\_triggered: False stow\_on\_each\_sample: False speed: 3 # Slower measurement speed (mm/s) lift\_speed: 10 # Faster lift samples: 2 # Measures twice for greater accuracy samples\_result: average sample\_retract\_dist: 5.0 # Moves up 5mm after the first contact pin\_move\_time: 0.680 (This was a recommendation from Google AI) After a successful G28, I start the Command screws\_tilt\_calculate After that, it moves cleanly to where it should. Then the pen retracts and it continues moving slowly and steadily. The pen shifts and the Z-motor continues moving… I previously had Marlin, and everything worked fine. No function works here: Probe, bed\_mesh\_calibrate, etc. Manual testing (QUERY\_PROBE) works without any problems. ---

I found the problem: I switched of the printer, but the cr touch was still iluminated. Cause the 5V comes via USB from the raspberry, so cut the 5V (red one) Now it is working First with a little bit of Styrofoam under the pin. that was working.. Now I started in reality. The same as before. connecting to the bed. Could be that there is a problem of the length of the probe? - Next Day: I put some plastik sheet between the mounting braked and the sensor. Then I started the measuring again. and it is working now. - ---
