This is getting silly, 3 times you post, I did try to help you with your first post. You didn't say you were using RPi3B to begin with. I did politely ask what your native language was, so we could find someone to help you, as it quite clear English is not your first language.
First of all I think you need to find some Linux info in your own language, this forum is not here how to teach people how to use Linux takes way too much time. Anything Linuxcnc we can help.

forum has made help any peoples how do linuxcnc to raspberry etc other linuxcnc problems, forum need help and teach all newbie how make somethink. my own language not have forum and maybe not many peoples who can help newbie user, Finnish language need be. but i believe not have many peoples. i has build many many cnc machine before but now think need one small simple dovetail tool made whit my old rpi3 board but search google lot and not have any image what can use, all has only lot problem code and install and what have kernel compile or what need doing not understand and know what need doing. need only image what can install to SD card simple not more need doing. same than normal computer can install linuxcnc 2,8,4 my daily used cnc machine, easy simple fast install and setting workig. no problems, why not has made normal image to SD card and can use similar than computer this working. not big job all computer engineer gurus and nerds. all not have nerd and understand linux code but lot have peoples who want use rpi3 cnc.

i just order some shift level converter can use whit rpi gpio can make out 3,3V to 5V all gpio pin, and then one optocoupler board can add rpi inputs safe, 5V in to 3,3V to rpi,
then can add all STEP,DIR,Enable pins traight to drivers DM556 i used normal,
but problem is were have image can use rpi3, not need be fast, this come only dovetail jig tool make long plank top dovetails not more, no need be full cnc, working area has need only XY axis, what has moved Z axis to 90 degree and spindle have horicontal not normal vertical system. simple hardware but image need old rpi3 board first.
