Tmc #43
Description
I have a TMC5160 stepper driver that I’m trying to get working.
The goal is to control it only via SPI, but I can’t get the driver to start up at all.
I’ve tried both SPI control and Step/Dir signals, as well as several C++ libraries, but nothing seems to work.
This is the official github repository for the panel:
https://github.com/FYSETC/FYSETC-QHV5160
Most recently, I tested with this library but the driver still didn’t respond.
I also have a TMC2209 driver, and with that one my motor runs perfectly over UART, so I know the motor itself is fine.
With the TMC5160, however, the motor doesn’t move at all — it doesn’t even hold torque.
Using a multimeter, I confirmed that it’s receiving the correct voltages (3.3 V and 16 V), GND is common everywhere, and as far as I can tell the pins are wired correctly.
It just refuses to start in any way.
I’m starting to suspect a hardware fault, but I’m not 100% sure.
Does anyone have any tips or things I should check?
Here is some images of the current wiring.
Thanks in advance to anyone who can help.
