M102 S-1 no communication #75

Closed mighur closed 10 months ago

mighur commented 10 months ago

Hello. Just installed BD sensor in BTT SRK 1.4 Turbo. Connections: SDA: (Green) Servo pin 2.0 GND: (Yellow) Servo GND pin CLK: (Orange) Probe pin 0.10 5V: (Red) NPWR servo pin (+5V) GND: (Brown) GND servo pin (GND)

I followed all github instructions and double checked with Chris Basement video. I commented/activated all indicated options.

At the end of pins_BTT_SKR_V1_4.h I'v added:

define I2C_BD_SDA_PIN 2.0 // Please change to the actual number which the SDA wire is connected to your mainboard

define I2C_BD_SCL_PIN 0.10 // Please change to the actual number which the SLK wire is connected to your mainboard

define I2C_BD_DELAY 20 // default value is 20, should be in the range [20,50].

Compiled marlin with no errors. Everything seems to work ok (temperatures, thermistors, movement X & Y, M119 gives expected results...)

Connected printer via terminal: M102 S-1 outputs:

recv: bd sensor version:\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff recv: read error. check connection and delay.

BTT SKR 1.4 Turbo board is brand new. Just buyed. Exact same behabiour with BTT SKR 1.3. Same output message. I fact I bought SKR1.4 because I thought It was a board issue.

M102 S-6: Does de thing and z axis goes up but after that, S102 S-5 outputs:

If I put a bit of steel near the sensor, the white LED lights. If I try to home Z:

Recv: echo:BDsensor connect Err! Recv: //action:notification BeltSKeR 1.4 bugfix Lista Recv: //action:notification BDsensor connect Err!: Recv: Error:Printer halted. kill() called!

¿What can I do?

the motherboard can't communicate with the bdsensor. for testing, you can use the EXP1 pins for the bdsensor, also try to increase the delay value from 20 to 40.

Finally solved. It was a mistake with the naming of pins. Thank you

markniu commented 10 months ago

Glad to know.

Can you please post the pin naming you used. I have same problem on skr1. 4turbo

mighur commented 4 months ago

This is what I have for BTT_SKR_V1_4

define I2C_BD_SDA_PIN P2_00

define I2C_BD_SCL_PIN P0_10

define I2C_BD_DELAY 20

Using Servo and Probe pins

Thank you. Ive tried those exact pins named exactly how you now outlined it. I will try actually cutting and pasting what you posted here. Thank you for responding.
