The problem is simple: these drivers do not work) But everything is not so simple, as you can think.
I have a homemade CoreXY printer and Chinese RAMPS-FD. At start I tested my printer with A4988 drivers, and everything was good, but it was too noisy. I installed DRV8825, and, when I send move command, X motor moves slowly and Y motor gets in hold mode. I tuned current correctly (I checked!), I installed drivers correctly (I also checked!), but it doesn't work.
I swapped X and Y drivers, bit it doesn't work too. The interesting thing is, despite drivers' swapping, the motors' behaviour didn't change: X motor still move slowly, and Y motor still enter hold mode.
I have DRV8825 on Z axis, and it works good. But it don't work at X or Y axis.
After all tests I checked DRV8825 at another printer, and they work good there.
Now I continue using my printer with A4988 drivers.
My brain is blowing... What I do wrong?
