Wire plug in Connection1.jpg Wrong

[brosskgm]

Just received your unit Today. Installing on Mega X with SKR V1.3 TMC 2208 and Marlin 2.1.2.4

Your Connection1.jpg picture in your instructions is not what is actually plugged in. Does not have the same colors as BLTouch install(BLTOUCHWIRESETUP Attached). Many of the other photo's only show 4 wires.

Also configuration setup in pins file mentions a SCL_PIN but it's not on the sensor(BD_Sensor Attached)

SKR V1.3 Pins file
#define I2C_BD_SDA_PIN P1_24 // Change to actual number which the SDA wire is connected to on your mainboard Z_MAX
(Will change to Z_MIN if code doesn't like Z_MAX as the pin and then use sensor for auto homing.)
#define I2C_BD_SCL_PIN P2_00 // Change to actual number which the SCL wire is connected to on your mainboard
#define I2C_BD_DELAY 20 // Default value is 20, should be in range [20, 50]

I changed all the wires according to the sensor and put the SCL where the CLK plugs in. Didn't smoke when turned on, the sensor only blinked a green light. Hope this means ok to continue with the setup. Tested the sensor closer to the bed and the green light stayed green so will print a new holder.

Was hoping to use Z_MAX pin for testing. Then will move to Z_MIN and adjust. Marlin complains about using X,Y,Z Max and X_MAX pins for dual z endstops is why all are on the MIN.

M102 S-1
Returns OK

M119
Returns:
X_MIN: OPEN
X_MAX: OPEN
Y_MIN: OPEN
Z_MIN: TRIGGERED
Z_PROBE: OPEN

Odd thing is the Z_Min endstop light is not on and Can touch to activate it. Sensor is on Z_MAX

Looks like it's not working. More configuraiton to do.

right, the SCL_PIN means the CLK pin.
there should some version string after M102 S-1 , else it's working.
and I just checked this skr v1.3 , there are signal filter capacitors on all the endstop pins, so we can not use those pins

please choose other pins like the EXP1 EXP2 or TFT

Hi Mark, Thanks for the quick reply.

I don't have the newer circuit version that plugs into the EXP1, EXP2

Do you have any instructions for the EXP1 or EXP2 with the current wires?. Already using the TFT pins for the screen. Finished wiring it to use the EXP1 GND, 5V, SDA, CLK and GND on EXP2

Changed the pins file to
#define I2C_BD_SDA_PIN P1_19
#define I2C_BD_SCL_PIN P1_18

Have it wired to EXP1 GND, 5V, CLK, SDA pins, and GND on EXP2

Now when turned on, solid green. Nozzle on bed. Then after system boots, fast flashing. Still needing more information for the wiring and programing for Marlin.

Thanks
Bob

are there some message returned after M102 S-1 like pandapi3d.com v1.2c

[brosskgm]

Plugged into EXP1 and Second ground wire plugged into EXP2

Command:
M102 S-1
Returns OK

Did the same thing when it was plugged into Servos and Z_MAX, just says OK

Couldn't find any setup information for the EXP1 or EXP2 pins and Marlin if other things need to be set.

When I plugged my old screen into the EXP1 and EXP2 sockets, screen worked fine. Just don't like the old style screen over the nice graphic style that uses the TFT pins.

I have the TMC2208s on this SKR V1.3 board also if that matters.

Hi Mark,

I decided to get the SKR V1.4 board since it has the Survo and Probe pins seperate. Will get in touch with you then.

Thanks
Bob
