(Mine is X=160 mm, Y = 160 mm and Z = 55 mm) X,Y,Z axis maximum travel distance Not your bed or axis dimension, how much your axis actually moved.

Microstepping, half step or full step configuration for stepper motor controller (В I choose 6th microstep for my linisteppers ).

X,Y,Z stepper motors step/revolution (eg:В 200 steps/rev for my stepper specs).

(My Linistepper min step pulse is 3 us, so 10 us isВ fine for me) If not sure, use default value, 10 us and trial and error method.

Your stepper controller, step pulse duration.

Default serial baudrate is now 115200! (Up from 9600).

But, I choose this version 0.9i for testing some advanced features. And version 9.0x also has some issues with PC side software in some case. Most of 0.9 user face difficulties in using this. This version is a bit different from old versions.

Grbl v0.9i Atmega328p 16mhz 115200baud with generic defaultДЄfter flashing the Grbl firmware, I connected with 115200 baud rate and hit enter key.

I used Xloader and flashing done after minutes. Another helpful source is вЂњShapeokoвЂќ, fully opensource and commercial CNC wiki.

Connecting Grbl with stepper controllers and CNCДЎ# The first test is to flash DIY Arduino board with вЂњGrblвЂќ.

It is time to assemble main controller after finishing DIY Arduino and stepper controller boards a few weeks ago. Thanks Grbl buys for developing such simple/effective controller. If the maker movement was an industry, Grbl would be the industry standard.вЂќ вЂњGrbl is a free, open source, high performance software for controlling the motion of machines that move, that make things, or that make things move, and will run on a straight Arduino. For stepper, I already built Linistepper controllers. Yes, there must be two important things for me, must be free, opensource and simple.ДЄfter reading many DIY CNC build logs, I choose Grbl controller with DIY arduino board. But I like to search the net for better option. Actually, I have some old laptop and PC with LPT builtin. Most of these software use LPT port for interfacing with stepper and CNC. But there is one drawback or limitation in this, LPT port. Even and old PC can beВ the best choice for this option. Actually, it combines half of CNC and stepper controller functions in PC software. I love this software and the simple setup of Mach3 liked CNC controller software. I have some experience in Mach3 CNC software in past.
