Today I have tried Trinamics TMC2100 (Called SilentStick on some online shops). I have not expect this much improvement on movements. I strongly advice to use these boards instead of DRV8825 or A4988.
They are drop-in replacement, it is easily could be placed instead of DRV8825 or A4988.

I use it since one month and it works really well! No sound, better smooth movement,... but I expected some strange thing in motor speed. sometimes the speed get higher,...

Slicing effects movement speed too much, maybe speed bump caused by this issue.
Will try slow down slicing during printing so movements get less effected by slicing.

I never slice during printing, it occurs just printing

Have you switched to spreadStep?
Also I suggest 1/4 microstepping instead of 1/8 (it is not available) and 1/16 (very difficult to achieve meaningful speed through current structure)

No, I read about spreadStep but I think it's not enabled on my printer, I'll test it. And Also think its in 1/16 microstep. I'll test SpreadStep and 1/4 steps.
Thank's
