Sensorless homing not working #68

Open Avasty opened 1 year ago

Avasty commented 1 year ago

Hello, i cannot configure my printer to home with this script.

Here's my config:

[autotune_tmc stepper_x]
motor: moons-ms14hs5p4150
tuning_goal: auto
sg4_thrs: 45
voltage: 24
extra_hysteresis: 1
tbl: 2

[autotune_tmc stepper_y]
motor: moons-ms14hs5p4150
tuning_goal: auto
sg4_thrs: 45
voltage: 24
extra_hysteresis: 1
tbl: 2

[autotune_tmc extruder]
motor: moons-cse14hra1l410a
voltage: 24

And there is a dump of stepper_x using DUMP_TMC stepper=stepper_x command

just disable coolstep for homing

Avasty commented 1 year ago

Which setting is that?

Still happening.... I set those commands 

set_tmc_field stepper=stepper_y field=tcoolthrs value=1048575
set_tmc_field stepper=stepper_x field=tcoolthrs value=1048575
AUTOTUNE_TMC STEPPER=stepper_y sg4_thrs=75
AUTOTUNE_TMC STEPPER=stepper_x sg4_thrs=75
SAVE_CONFIG

Do i have to add this into my homing macro? I home the printer once all is ok... After that second homing is not working again.

Same here. Normally my TMC5160 work with sensorless homing at driver_SGT: 2 and noise level is ok.

My hope was that Autotune can even decrease the sound level and make the motors run cooler.

Reality is, that motors beeing louder (even at idle they wine pretty loud) and sensorless homing doest work any more (sgt set in autotune section, set homing speeds according to description and tried to reduce homing current).

If anyone finds a working solution, just let us know :)
