• updated README

µCNC v1.6.1

µCNC version 1.6.1 adds Bluetooth support for the RP2040 core (Raspberry Pi Pico W) and EEPROM emulation for STM32F4.
STM32 platform is also improved to better support MCU variants.
Some issues were also fixed

Added

µCNC v1.6.0

µCNC version 1.6.0 adds support for the RP2040 core (Raspberry Pi Pico and Pico W).
WiFi is supported on Pico W. BT is planned to be included too.

This also removes tinyUSB files from code to an external library that is easy to update and maintain.
Further improvements to make the Web Config Tool easier to use on both Arduino IDE and PIO are implemented.

Added

• added core support for RP2040 MCU (#360)

Changed

µCNC v1.6.0-alpha

This is the alpha release of version µCNC version 1.6.0
This release is based on v1.5.7 and adds initial basic core support for Raspberry Pi Pico

For test purposes only!

µCNC v1.5.7

µCNC version 1.5.7 adds basic support for lathes (like spindle synched motions and lathe radius mode, via additional µCNC modules).
The internal machine states logic was reworked to reduced the risk of undesirable states/results.
µCNC now also adds option to supports internal height map generation that is mainly targeted at PCB milling without the need of external applications. With this feature a new subset of Gcodes is added (G39 - build map, G39.1 - disable map, G39.2 - re-enable map)
Several bug fixes were also addressed in this version.

A special thanks to @etet100 for detecting and fixing a bug related to servo control and also detecting and testing a random issue with homing motion.
