v-minion sensorless homing
Hi,
I still have problem to configure sensorless homing on my v-minion.
then I resume what I did and what I have as problems. 1° I put the jumper for homing under x and y drivers as it is noticed in the Btt skrat documentation. 2° As It is noticed in Ratos printer.cfg I copied the sensorless-homing-tmc2209 in the root and uncomment [include sensorless-homing-tmc2209.cfg] in the printer.cfg 3° put driver_SGTHRS to 255 and start first homing... normally It must not move at all and on my side the carriage go to end and don't stop at all.... I have to make a emergency stop. I don't know what's wrong

can you upload your printer.cfg please?
we need a bot for this
hehe I asked Mitsuma about that a LONG time ago, and basically there isn't one
no someone will have to make one i guess
thanks for help
can you take a picture of the top of your board?
just to avoid the possibility that we're conflating problems here, please remove klipper_tmc_autotune. You can reenable it once sensorless homing is triggering correctly.
I thought i had read something about this. And indeed, klipper_tmc_autotune makes sensorless homing work differently. From their docs:
This autotuning extension can be used together with homing overrides for sensorless homing. However, remember to adjust the sg4_thrs and/or sgt values specifically in the autotune sections. Attempting to make these changes via gcode will not result in an error message, but will have no effect since the autotuning algorithm will simply override them. Also, check the pinouts of your stepper driver boards: BTT TMC 2240 boards require configuring diag1_pin not diag0_pin, but MKS TMC 2240 stepsticks require diag0_pin and not diag1_pin. There may be other unusual drivers.So my guess is your problem stems from installing a third party klippy extra and not knowing how it affects your setup. that said, i've been eyeing klipper_tmc_autotune for a while now, and i like it a lot
Send you that tomorrow…
I Will try it … Thanks for help. Keep your informed.
@miklschmidt you are right man... Now it works...
but now can I use TMC autotune ?
I just reactivate tmc_autotune and homing is not working any more
all is working ... just have to speed up the homing speed
excellent 👍
