Marlin: Sensorless homing with TMC 2130 not working when homing all axes at once

Created on 4 Feb 2018  ·  3Comments  ·  Source: MarlinFirmware/Marlin

Hi

  • Description:
    I have some issues using sensorless homing feature of Fysetc 2130. SPI - resistor is soldered out, CF4 and CFG5 are properly soldered. When Homing via GCODE "G28 X", X homes successfully by sensorless homing and detects the end of the axis. Same for "G28 Y". However, if I say "G28" or "G28 XY", both axes are raming into the end without detecting anything.

  • Expected behaviour:
    Proper detection of sensorless X and Y endstops

  • Actual behaviour:
    "G28 X" and "G28 Y" working fine with sensorless homing but "G28 XY" and "G28" do not (ramming without detection)

  • Steps to reproduce:

    • MKS Gen L 1.0

    • all axes TMC 2130 (so far properly working)

    • Marlin Tarantula (1.1.8 with quick setup from here ( https://github.com/JimBrown/MarlinTarantula )

    • My current config:

Thanks in advance

Thanks a lot! I would never have found that one. Works perfect!

See if adding this to the very end of quick_home_xy helps, and you may then be able to use QUICK_HOME again…

    #if ENABLED(SENSORLESS_HOMING)
      safe_delay(500); // Short delay needed to settle
    #endif
