class TMC5160Stepper' has no member named 'SGTHRS

[MarkEvens]

What is a replacement for this in TMC5160?

and driver.VACTUAL(50000); and driver.SG_VALUE() this two also.

[WillemBrx]

Same problem. Can't do anything with stallguard

[cattledogGH]

void sgt (int8_t B)
void sfilt (bool B)
uint16_t sg_result ()

These Stallguard functions are all Public Member Functions inherited from TMC2130Stepper.
It is indeed possible to use Stallguard with the TMC5160.

Thank you. Could you give me an example on how to use that? maybe I can send you the code to take a look at? I would be very grateful!

[cattledogGH]

Typically, I have first monitored the running stepper and determined the sg_result value when running and when stalled. Then in the application I have read the sg_result and compared it to a value and if it's less than that value I call it a stall detected.

If you want to post some code for review, do it here, and make a minimal, reproducible, example which demonstrates your issue.

When i hold the motor with my hand

[WillemBrx]

The strange thing is that i do get a SG_result but only when I restart the esp32
