What about using some Trinamic 5160 drivers over spi/uart? Instead of step/dir.

TMC5160-EVAL seem to be an excellent product. Thanks for this information. I'll keep this in mind for another project.

For this project, it's out of budget. One TMC5160-EVAL costs 100 € where a lot of five DRV8825 cost 15 €. But agreed with you TMC5160-EVAL and DRV8825 are totally different in term of functions and power.

How high voltage do you wnt to run? Check out the 5160 stepstick. Super cheap. And there is also the 5160 bob. If you dont have super high power check out trinamic 5161. 5161 have fets included.
