LinuxCNC with Raspberry pi 4

Hi everyone, I'm fairly new to this. You can say I am a noob in Linux.

We want to build a CNC machine for testing stuff. I'll be using nema 23 and 17 motors connected to TB6600 motor drivers as well as limit switches and other components down the line. This will all be connected to a raspberry pi 4 and we want to use the linuxcnc to control the motors and send gcode onto them.

I wanted to know if I would I go about the configurations on my Raspberry pi4 and the components so that the software can recognize these and give them control. i searched that i need to configure or map the GPIO pins in the HAL? any responses would be greatly appreciated. Thanks!

have anybody make rpi4 working linuxcnc, what need doing gpio pins config, this hal,demo and html not help anything what need doing, not understand what must make, ewer not has written and understand code, only test run "blink" code and working.

just buy rpi4 and encoder wheel, buttons, rotate switch, shift level converter 3,3V to 5V and stepper motor drivers DM556 and nema 23 470 OZ/ 3 Nm motors, and install rpi4 linuxcnc image to card and run image, ok, but were is config wisard gpio pins ?
config wisard has only paraller port pin config.
pnc config has only ower expensive mesa card config.
how config all pins to rpi4 gpio ???? has anybody make this and can tell step by step or send config files what need rpi4 working whit this linuxcnc rpi image.
image boot and run ok, step conf wisard no help how gpio pins setting.
