Internal error on command:"G28" #65

Closed rolohaun closed 8 months ago

rolohaun commented 11 months ago

I am using the BD_sensor on a Manta M8P plugged into the BLtouch port. I have verified the sensor works, but when I try to do a G28 I can an error.

If I remove the BDSensor section the printer homes fine

I am not using any pin aliases or anything my config is below

[BDsensor] sda_pin: PB2 # Don't use aliases for the board pins scl_pin: PB1 # example of connecting to main board Creality V4.2.7 delay: 20 # 20us per pulse, this value should be >=20 but must be below 50 z_offset:0 # this z_offset must be set to 0. z_adjust:0.0 # z axis adjustment, replace the z_offset function. within -0.3 to 0.3mm x_offset: 0 y_offset: 0 no_stop_probe: # enable this for fast probe, the toolhead will not stop at the probe point. position_endstop: 0.8 # the Z axis will stop at this position (mm) while homing z, recommend value is 0.4~1.0 speed:0.8 # this speed only works for the z tilt and PROBE_ACCURACY command.

what's error? you can attach the klippy.log file should be better to find that the error.

I got it, I found out a bed mesh is needed for the probe to work, just wasn't clear in the install guide

Thanks, I will this into the guide.

Please add this to the instructions. I was racking my brain trying to fix the error and almost gave up. Thank you for all the hard work.

Hi, let me start by saying that I'm new to Klipper. I have a self-built Corexy printer , octopus v1.1 . Running G28 from the terminal I get an error. I'm sure I'm doing something wrong but I've been banging my head for too many days now. Can you help me? I attach log files Starting Klippy....txt e .cfg

This is the same error

    self.config.getsection('bed_mesh'), self.bedmesh.bmc.probe_finalize, self.bedmesh.bmc._get_adjusted_points())
AttributeError: 'NoneType' object has no attribute 'bmc'

just add the section bed_mesh in your printer.cfg, here is an example

Great! I thank you! The printer finally moves. Unfortunately I have other errors, I'll recompile it, I'll do it again and hope for the best

Hello @markniu , Same problem with the recent Klipper Update (Release: v0.12.0-98-g5e433fff). Here is my Klippy.log for a custom VCore 3.1 klippy.log

Chienhuycu commented 10 months ago

I found this on my log:
File "/home/pi/klipper/klippy/extras/BDsensor.py", line 1190, in home_start trsync.start(print_time, self.trigger_completion, expire_timeout) TypeError: MCU_trsync.start() missing 1 required positional argument: 'expire_timeout'

markniu commented 10 months ago

Hi, you need to update the BDsensor.py file too, since there is an important update of klipper that change something about homing with probe.

Hi @markniu, Is there a guide ?

markniu commented 10 months ago

you can try this in the ssh

cd ~/Bed_Distance_sensor
git pull

Thank you @markniu , I have just update with MoonRaker Update_Manager. Looking good
