Grbl **STM32** is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. It will run on a STM32F746 (Open746I-C Standard from **[Waveshare](https://www.waveshare.com/product/mcu-tools/stm32/open/open746i-c-standard.htm)**).
The controller is written in highly optimized C utilizing every clever feature of the STM32-chips to achieve precise timing and asynchronous operation. It is able to maintain up to **200kHz** of stable, jitter free control pulses.
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 includes full acceleration management with look ahead. That means the controller will look up to 18 motions into the future and plan its velocities ahead to deliver smooth acceleration and jerk-free cornering.
