Can't home with new firmware #102

Closed Mharasim1 closed 7 months ago

Mharasim1 commented 8 months ago

After flashing new firmware im getting this error when trying to home z: Unable to read tmc uart 'stepper_z' register DRV_STATUS Z axis moves fine if i use SET_KINEMATIC_POSITION There are a few BD Sensor errors in klippy.log klippy (9).log

did it happen every time while homing? how about send M102 S-1 before homing gcode G28?

Mharasim1 commented 8 months ago

I get this after sending M102 S-1 : BDsensorVer:V1.1bpandapi3d.com ,switch_mode=1,collision_homing=1,collision_cal=1 but it still doesent home. It was homing before i flashed new firmware to the sensor @markniu

the bd sensor and tmc are two independent from the hardware and code, so not sure what's the reason. one way you can try to debug: remove the BDsensor section and replace the endstop_pin: probe:z_virtual_endstop with endstop_pin:PB8 in the stepper_z section, move the nozzle far enough from the bed and home again to see if the z axis is moves towards to the bed direction, and then power off the printer.

for the klippery source code, seems the error is that it can not read data from the tmc and timeout. image

I removed bd sensor section and and removed endstop_pin: probe:z_virtual_endstop and it tried to home fine. but when i add bd sensor to config i get tmc error So its something from BD sensor that is causing that @markniu

could you try to replace a code in the BDsensor.py as following? that will let the homing process as old firmware.

before

  def home_start(self, print_time, sample_time, sample_count, rest_time,
                   triggered=True):
        self.BD_Sensor_Read(2)
        if "V1." not in self.bdversion:
            self.BD_version(self.gcode)
        clock = self.mcu_endstop.print_time_to_clock(print_time)

after


  def home_start(self, print_time, sample_time, sample_count, rest_time,
                   triggered=True):
        self.BD_Sensor_Read(2)
        self.switch_mode = 0
        clock = self.mcu_endstop.print_time_to_clock(print_time)
