Hello everybody.
I'm trying to start my new CNC machine. It's just cheap CNC 1010 15W Laser Engraver Machine GRBL Control 2 Axis. The first thing I decided to start was generating a g-code in the Inkscape and editing a bit.

Since I use the Linux operating system I installed the candle program. Because in my opinion it is the simplest. When I sent the code to the machine. The machine began to move as expected along the given trajectory, but after the command M3 C255 (M4 C255) the laser was turned on at a very low power (does not cut or engrave the material). I tried to disconnect the wire ttl after which the laser began to cut through the material. Maybe I need to add something in the candle setting or add something in the g-code? Since I'm a complete beginner in CNC, I don't even know where to start. Thanks in advance for any help.
