Error stop called because of bltouch error restart with m999

Hello,

I’ve been working on getting a BLTouch sensor to my prusa i2. I’m running ramps 1.4 and octoprint. When my octopi starts this is what the terminal outputs:

Recv: ok
Changing monitoring state from 'Error: STOP called because of BLTouch error - restart with M999
' to 'Offline'

I’m able to restart the serial connection and run Gcode commands. I found some troubleshooting suggestions here and this are the results of my testing:

1. Blue LED will be ON if a servo signal is present. Blue LED is faint.
   Result: Blue LED is on
2. M119 ; should return OPEN. If not check that the BLTouch is enabled in the configuration. If enabled then check wiring and check that the correct pin is being used.
   Result: Open
3. M280 P0 S10 ; should deploy the probe and the orange LED will be OFF.
   Result: probe acted as it should
4. M119 ; should return OPEN
   Result: Open
5. M280 P0 S90 ; should stow the probe and the orange LED will be ON
   Result: probe acted as it should
6. M280 P0 S60 ; puts it into the M119 test mode.
7. The probe should remain stowed and the blue LED should be OFF.
   Result: probe acted as it should
8. M119 ; should return TRIGGERED
   Result: probe acted as it should
9. M280 P0 S160 ; returns it to normal operation
10. M119 ; should return OPEN.
    Result: Triggered

This is the output of terminal when I run G29:

> Send: G28

I’ve attached is my configuration.h file. If anyone has any suggestions about what my next step to get the sensor and printer running correctly I would certainly appreciate it.

Thanks so much!

Hy everyone, i just had the chance to install a cheap 3d touch, that i had laying around from a long time, to my ender 3 pro but i keep getting this error when i want to level the bed.

I have an mks gen l v1.0 motherboard with tmc2208 for XYZ and A4988 for E , tft28 v4 touchscreen, i have just flashed Marlin 2.1.2. Also i have 2 5015 fans installed.
i have followed several videos and tutorials for installing this touch probe, G28 sometimes work sometimes it doesn’t, it homes X/Y then goes to the middle, raises up a little, stays, probe down, come up then probe again but at the first or second time for sure i will get this error sayng that is something wrong with the bltouch. If it manages to pass the G28 and i send G29, it preheats then goes to the first corner and the error pop after the first probe.

The wires that come out of it are soldered directly to the long ones that goes to the motherboard where i have some connectors that i have squishes a little so i can fell that they make good contact with the pins on the board. the connections are as in the diagram for the mks gen l, black/white to z end stop — gnd/sign, the others to the servo pins.

i also have messed with internals, the wires are soldered good inside, i have magnetized the magnet again and it atracts verry well so i have changed the termo tube and cut it a bit longer so that the set screw doesn’t get in contact with the magnet directly but instead there is a bit of a distance enough for the coil to attract and reject it down. there was a play in the channel where the tip goes inside, the part with the magnet on top had room to go around since the hole in the plastic was bigger (hence the tip doesn’t stay perfectly straight) and i have placed another layer of termo tube just on the top of the magnet so it fills a bit more the space but still has room to move a bit, it work even if it not perfectly straight with the plastic housing.

i have tried different distances for the set screw so that is closer/further away and i got better results when it was closer for that i am thinking that there might be a time that is exceeded when it takes a bit longer for it to engage when the screw is further up and has to move more. Or the magnetic field that measure something might be messed.

At some point i got the error «echo:endstops hit: z:-0.11» (and even bigger like ~ -1.X i think) wich i don’t understand since it homes first with G28 then G29 gives me this. Isn’t the 0 position the one first measured with G28? i haven’t moved anything just the z axis moved by g code some mm up that is set in the firmware

Here are all the changes i have done in marlin so far for everything i have on going with the printer:
Changes in configuration.h marlin;

#define MOTHERBOARD BOARD_MKS_GEN_L //1113

#define SOFT_PWM_DITHER
#define SOFT_PWM_SCALE 1
#define PROBING_HEATERS_OFF
//#define WAIT_FOR_HOTEND
#define DELAY_BEFORE_PROBING 200

Changes in configuration_adv.h

#define BLTOUCH_DELAY 500
#define E0_AUTO_FAN_PIN 7 //for hotend fan
#define BABYSTEP_ZPROBE_OFFSET
#define BLTOUCH_FORCE_SW_MODE

Also if there is anything i have to modify for the serial com to work and not interfere with the tft screen would be great, the SERIAL_PORT -1/#define SERIAL_PORT_2 0 doesn’t allow me to set to -1. It works now but just to be sure that they don’t interfere.

I would really appreciate some help from anyone!
Regards, Alex!
