Problem with Original BLTouch v3.1 in Marlin 1.1.9

[RedJohn14]

Hello,

I installed Marlin Build from your repo here: (v.1.1.9) https://github.com/MNieddu91/Marlin-AI3M-BLTouch

My settings in configuration.h looks like this: `//#define PROBE_MANUALLY //#define MANUAL_PROBE_START_Z 0.2

/**

• A Fix-Mounted Probe either doesn't deploy or needs manual deployment.
• (e.g., an inductive probe or a nozzle-based probe-switch.) */ //#define FIX_MOUNTED_PROBE

/**

• Z Servo Probe, such as an endstop switch on a rotating arm. */ //#define Z_PROBE_SERVO_NR 0 // Defaults to SERVO 0 connector. //#define Z_SERVO_ANGLES {10,90} // Z Servo Deploy and Stow angles

/**

• The BLTouch probe uses a Hall effect sensor and emulates a servo. */ define BLTOUCH if ENABLED(BLTOUCH) define BLTOUCH_DELAY 100 // (ms) Enable and increase if needed

  /**

  • BLTouch V3.0 and newer smart series
  • For genuine BLTouch 3.0 sensors. Clones may be confused by 3.0 command angles. YMMV.
  • If the pin trigger is not detected, first try swapping the black and white wires then toggle this. */ //#define BLTOUCH_V3

    if ENABLED(BLTOUCH_V3)

    define BLTOUCH_FORCE_5V_MODE

    define BLTOUCH_FORCE_OPEN_DRAIN_MODE

    endif

    endif`

I used the original BLTouch v3.1 from here: https://www.amazon.de/gp/product/B075B57CHD/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1

I also tested your new repo Marlin 2.0.x: https://github.com/MNieddu91/Marlin-Ai3M-2.0.x-BLTouch

I have home everything with G28 and use G29 all works perfekt. BLTouch Pin comes out but if I TRIGGERED it from hand nothing happens Z axis not stop!

If I home everything again with G28 and looks with M119 I see this: < 13:10:36: x_min: TRIGGERED < 13:10:36: y_min: TRIGGERED < 13:10:36: z_min: TRIGGERED < 13:10:36: z2_min: TRIGGERED < 13:10:36: z_probe: open

The z_probe status won't change. I TRIGGERED the Pin manual but the status won't change. The Server cable on my motherboard is correct because I can use this command without any problem:

M280 P0 S10 ; pushes the pin down M280 P0 S90 ; pulls the pin up M280 P0 S120 ; Self test – keeps going until you do pin up/down or release alarm M280 P0 S160 ; Release alarm

Only the trigger status will not work Z axis not stop! Any idea what the problem is?

Attached you find a picture from my BLTouch mount in the printers head. And a picture from the cable on my motherboard. I have the new Board 1.1.

I had the same problem, but believe I have resolved it. Following the instructions in the Configuration.h file, I swapped the black and white wires. That allowed me to stop the Z-movement by manually triggering the pin.

I'm continuing to work out my configuration now, and will update here if I have any further issues.

All seems well now - I've set my Z-offset and it seems to level correctly. Pending a test print, I'm calling this a success, and will set about cleaning up my wire mess :)
