GRBL-Advanced/README.md

2.1 KiB


Grbl-Advanced is a no-compromise, high performance, low cost alternative for CNC milling. This version of Grbl-Advanced runs on a STM32F411 Nucleo Board.

It accepts standards-compliant g-code and has been tested with the output of several CAM tools with no problems. Arcs, circles and helical motion are fully supported, as well as, all other primary g-code commands. Macro functions, variables, and most canned cycles are not supported, but we think GUIs can do a much better job at translating them into straight g-code anyhow.

Grbl-Advanced includes full acceleration management with look ahead. That means the controller will look up to 16 motions into the future and plan its velocities ahead to deliver smooth acceleration and jerk-free cornering.

  • Built on the wonderful Grbl v1.1 (2017) firmware written by Sungeun "Sonny" Jeon, Ph.D. (USA).
