I have the same setup and no issue. I noticed that it probed the front row correctly (2 touches per location) but then when it went back to the 2nd row it probed the same spot rather than move left and do the other 2 locations. |

Hi, I've got the same problem on an Ender 3 Max. I've correctly set the bed size in the configuration.. but when I auto home, I can see the printhead is farther from the middle than expected. When I try and level, the X axis crashes and the previous two points are offset too far to that side as well. Did you figure this out? |

I've got the same problem as OP. It probes spots 1-4 fine. Spots 5 and 6 get probed in spot 4 and the bottom 3 all get probed in the bottom right corner. That's why it looks like it's probing multiple times in one spot. It seems like it is having issues making the x axis move left, but right movement works fine. Still have no clue how to fix it. |

This is a timer issue conflict with the stepper ISR and the probe timer and a whole gamut of other timer conflicts that as far as I know are fringe case timer conflict/issues that were never fixed in maple. This was reported by me (and others with various other issues related to timers) upstream on marlin. It's an issue only in the Maple HAL not STM32HAL, and the devs who looked into it decided that since they were intending to retire Maple at some point and decided putting resources into getting all the Maple boards supported by the STM32HAL was better use of time. They are keeping around the maple HAL right now for legacy, but it will eventually go away. This issue also is on more boards than just the creality ones, i had the exact issues described here on a BTT SKRE3Mini. And moving to STM32HAL solved it completely. See MarlinFirmware#21429 and MarlinFirmware#21488 All firmware on these boards and others if based on the Maple hal suffer from lcd flickering, random no prob deploys, tool head randomly crashes to bed or axis because an end stop trigger was missed. And so forth. |

@tititopher68-dev I've tried to compile code. I downloaded source code, moved configuration.h and configuration_adv.h from directory Marlin-bugfix-JyersUI/Configuration Files/E3V2 Tempates/BLTouch-3x3 to Marlin-bugfix-JyersUI/Marlin. I changed also configuration as you described above (Marlin / SRC / HAL / STM32F1/Hal.h). Also replaced old files by new ones (provided by you).Then I compiled code with success. I put it on the sd-card but I am not getting any response during boot up. LCD display is completely blank/ no interactive. If I compiled source code with default configuration files, compiling was succesfull and also boot process - of course without levelling possibility. Did I miss something or did I do it in wrong way? Thanks. |

Hi,
after installing BLTouch v3.1 on my Creality Ender 3 v2, I am facing the issue with x and y axis. During auto bed leveling seems like printer is trying to go outside x, y position of bed and make levelling there. By doing that it is crashing to printer's frame. It is happening for x and also y axis movement. My motherboard version is 4.2.2, I've tested many different firmwares but situation is still the same and I am not able to make auto bed levelling successfully. Manual movement of x/y/z axis is working correctly. Probe offset X and Probe offset Y are configured correctly.
Video of behaviour - crashing to the printer frame visible at the end of video
I am using direct connection from BLTouch to the motherboard port (no adapter used).
I am using pre-compiled firmware version: E3V2-BLTouch-3x3-v4.2.2.bin
I've tried many different versions 5x5, also HS but still the same issue.
Could you please advise me what I can do to fix it? Is it needed to make any configuration changes in firmware and compile it? Can you advise what kind of changes?
Thank you.
