What is the difference between grbl and mach3

Mach3

Mach3 is a numerical control software developed by bai American ArtSoft company with Windows as the platform.

The system version must be zhiWIN XP or WIN2000. The Mach3 software uses the LPT of the PC computer, or the USB port as the input and output of the CNC device. Pulse and direction signal, control stepper motor or servo motor driver. So as to realize the control of CNC machine tools.

This software supports all international standard G codes. Up to 6 axes can be controlled.

5-axis linkage with linear interpolation function can be achieved. High precision of complex parts Processing, the highest control accuracy is 0.0001MM.

When complex functions are required, MODBUS devices can be used to control the control of tool magazines, fixtures, and chip conveying mechanisms.

A simple system can be achieved with one parallel port. Two complex parallel ports will do. Its The peripheral switch points can be edited with VB for sequential input and output.

Grbl

And Grbl is an embedded G code compilation and motion controller for Arduino/AVR328 chip. Grbl is high performance, low cost, based on parallel port motion control, used for CNC engraving.

It can run on Vanilla Arduino (Duemillanove/Uno) as long as it is equipped with an Atmega 328 chip. The controller is written and optimized by C, using every smart feature of the AVR chip to achieve precise timing and asynchronous control. It can maintain stable, unbiased control pulses over 30kHz. It accepts standard G codes and has passed the output tests of several CAM tools.

The movement of arcs, circles and spirals can be perfectly supported like some other basic G code commands. Functions and variables are currently not supported, but will be included in future releases as a preprocessor.

Grbl includes complete forward-looking acceleration control. It means that the controller will plan the running speed 16 to 20 movements in advance to achieve smooth acceleration and impact-free turns.
