TwoTrees TTS-55 Configuration

Hi, I just come to compile LinuxCNC on Debian 11.
I'm new to the application.
For now i'd like to drive 2D+light laser TwoTrees TTS-55
Until now i used it with LaserGRBL but i'm designing my thinks into Linux.
I do not make artistic work : I'm an electronician and the main thing i must reach is to
produce PCB cards. I allready have succès with the paint burning method.
I'm begining with black en white image with pads and tracks printed on it 
no greyscales no special effet : it's quite trivial.
But the speeds, and algorithm to print is very important... which i actually do not control with 
laserGRBL.

The machine is accessible via a tty port encapsulated into usb.
[19580.062336] ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0
The motherboad is an arduino and the firmware is GRBL Firmware if i'm not mistaking.
And the usb-serial chip is ch341-uart.
USB works pretty well : i'm able to make the machine work if à redictect some code into the port.
But i have no control at all that way.
I would like to know if other people did configure the same machine or something cloth w​​​​​​ith LinuxCNC.
Or documentation about ports configurations and the way to manage files.
I thank you in advance.
