you can increase the communication speed by reduce the delay
value in section [BDsensor] from 20 to 8 for BDsensor V1.2, and also try to slow down the printing speed of first layer or the max_accel
value.
here I just added a variables for the sample time,need to update and compile&reflash klipper.bin
so did the update for this and added the rt_sample_time line to my config and now I get a "Unable to obtain 'I2CBDr' response" during homing when starting a print.
seems that you have updated the code, but need to compile and reflash the firmware.
you mean flash the BDsensor or klipper? because I reflashed the printer this morning and still have the same error after it homes for printer start
flash the klipper.bin. you can try again. maybe you forget to recompile or the flash not success. the mcu can't recognize this new command rt_sample_time if the firmware is not updated.
recompiled and reflashed the printer. again only getting the Unable to obtain 'I2CBDr when the printer tries to home after starting the print. if I go back to doing KAMP I have zero issues. it's only when I try to use realtime Z
could you check if the BD_sensor.c is the latest as the shown below, and how about remove the rt_sample_time in the cfg file?
you can test it just send BDSENSOR_SET REAL_TIME_HEIGHT=0.3 and no need to start a print.
Also try this My klipper says dirty after installing bdsensor If it does... Log in SSH Run ./Bed_Distance_sensor/klipper/uninstall.sh (If this doesn't work. Run Sudo chmod +X ./Bed_Distance_sensor/klipper/uninstall.sh) Sudo rm -r ./Bed_Distance_sensor Go back to Mainsail Do soft recovery on klipper Make sure everything is updated Reboot Now start marks install guide again When you run make and the list scrolls through make sure BD Sensor is in the list.
This script does not seem to like Kiauh. So you will need to flash it at command prompt.
I'm getting this issue again. I had it working for a bit and then updated klipper, BD sensor, Moonraker etc and now I get it again. I've added rt_sample time and reduced delay to 8. The before layer change gcode is in the sliced. I've removed all bed mesh related settings and data from my config.
How about the CPU loading while printing with SSH command htop
?
and maybe need to slow down the printing speed of first layer.

Thanks Mark
Ok. I'll give that a go.
I slowed down 80%
If I enable it manually without printing the bed does move up and down.
I just did a print of a different gcode and worked correctly. This wasn't sliced and uploaded recently.
or continue to increase the value rt_sample_time. if still happen, you can disable the real time level to see if it caused that problem.
I tried all different values for that went up to 32. Yes it completed with realtime levelling disabled. I just tried reslicing again but same result. 🤔
I'm getting a MCU 'mcu' shutdown: Timer too close when running real-time Z Adjust. if I go back to just using KAMP or the bed mesh I don't have the issues. this happens with my BDSensor 1.1 and 1.2 running on Ender 3's with 4.2.7 Creality MCU's and Pi 4 4GB
