GRBL 32-bit 250KHz 3-Axes CNC Controller STM32F103 ARM Demo GRBL32 F13

A 3-axis CNC Controller based on the STM32F103C8T6 in module form, aka “Bluepill”. Designed as an upgrade to existing GRBL installations, providing higher resolution for PWM control (Spindle/Laser), smoother motion, and a fast step rate of 250KHz for each axis while under 3-axis coordinated motion. GRBL32 firmware is a port of GRBL to the STM32 platform. More details at Shop on ebay:
