TMC2208 behaving strange (?)

#1

Hi guys,
I purchase a set of TMC2208 for my Geeetech A30, Install them, adjust Vref’s, changed direction and try some basic moves.

On E,Y and Z all good, no problem, but on X I see something that not make any sense for me.
Every time the printer start file, all axis go home, reach the endstop switches fine, but the X stays there and disengage.
I try to manual move from the menu, and nothing, I can move it by hand while the others working and locked.

I tried to swap drivers but it’s the same…
Push back the old A4988 just to the X and it’s working fine…

Any ideas?
