What happened?

I couldnt find any information on how to setup two tmc5160 drivers to a mks dlc32 v2.1. GPT says i need to parallel connect the miso, mosi and sck of both driver to certain pins. Im not sure how to do that, i bought the controller and stepstick driver especially to not do something like that.

GPT says i can use the tmc5160 driver as uart, how is that possible?

can anyone provide a guide or information how to make it work? Thanks in advance.

Use standard_stepper: as the driver type instead of tmc5160. The tmc5160 driver type is for SPI-configured 5160s.

I interpret your statement

i bought the controller and stepstick driver especially to not do something like that.

to mean that the 5160 modules that you purchased are factory configured in "standalone mode", where all the configuration is done via fixed voltage levels or jumper settings on the MS pins. My answer above depends on that assumption.

If my interpretation is incorrect, and the 5160 modules are setup at the factory for configuration using SPI, then you will have to change a jumper on the module, similar to what this says https://wiki.fysetc.com/S5160_V1.2/ , otherwise you will not be able to use them with DLC32. The reason I say "similar" is because there are many vendors of modules like this and they all have different layouts. Since you did not tell us exactly what you have, I have to give a handwaving answer instead of an exact one.

One more consideration: 5160s tend to draw a lot of surge current which can cause some power supplies to drop out, which then causes the 5160 chip to shut down. If you have unexplained glitches or failures when you are using the device, that could be the cause. The power level of 5160s is sometimes too much for the power delivery circuitry on stepstick boards.

Thanks for your replies, it sounds like the tmc5160 is a bit too complicated for me, i decided to use my tmc2209 and run my nema23 stepper motor with half its power. Luckily i have a good fan keeping my driver warm at max. even under full load.
