µCNC v1.7.1

Version 1.7.1 rolls out a couple of additions and some fixes to jogging
A shout out to @patryk3211 for giving is first contribution to µCNC

Contributors

@patryk3211 - new events at each axis homing (#393)

Added

• new events at each axis homing start and end to allow custom actions like probe/limit deploying #393

Changed

• modified ~ char logic to allow passthrough if a Grbl system command is being sent. This allows to write short file names to sd card addon module via commands (#395)
• system menu now displays the axis realtime position while axis is locked for jogging (#398)

Fixed

• fixed position unshynchronized after cancaling a jog motion (#399)
• system menu jog command bad string initialization leading to random buffer overflow errors (#398)

µCNC v1.7.0

This is the final release of version 1.7. This version introduces the new system menu module.
This module was designed to handle all the user input and menu render logic for graphic displays and LCD's.

The module core was also modified and introduces breaking changes from the previous version so be aware of the version of modules to include with this release.

An example of system menu running on RAMPS/Mega board with the graphic_display module for RepRap Discount Full Graphic Smart Controller can be seen here

Added

• added system menu alarm screen rendering logic (#379)
• added system menu modal popup (#380)
• new system menu module to handle all display related logic (#374)(#379)(#380)
• SKR Turbo v1.4 Wifi Serial boardmap config (#385)
• added default PINS for RepRap Discount Full Graphic Smart Controller on several boards (#374)

Changed

• system menu tweaks and minor fixes (#391)
• reviewed TinyUSB mcu macros (#384)
• core module system function declaration tweaks (#373)

Fixed

• fixed some deprecated PIN checking with ASSERT_PIN that caused compilation issues depending on the enabled options (TMC drivers, and RAMBO digipot and digistep) (#382)
• fixed USB hang on high rate gcode stress with NXP LPC boards (#386)
• fixed extended M Codes parsing for TMC drivers when not all AXIS are defined leading to unexpected behavior (#388)

µCNC v1.7.0-beta

This is an early release of version 1.7. This version introduces the new system menu module.
This module was designed to handle all the user input and menu render logic for graphic displays and LCD's.

The module core was also modified and introduces breaking changes from the previous version so be aware of the version of modules to include with this release.

As an example, the added pre-compiled firmware is for RAMPS/Mega board with the graphic_display module for RepRap Discount Full Graphic Smart Controller. The display uses the u8g2 library handle rendering.

Added

• new system menu module to handle all display related logic (#374)(#379)(#380)
• SKR Turbo v1.4 Wifi Serial boardmap config (#385)

• fixed ? command being cleared before responding depending on the execution point were the call was made. This will make the status command more responsive (#376)
• 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

• added EEPROM emulation to STM32F4 mcu boards (#370)
• added Bluetooth support for RP2040 (#364)

Changed

• better STM32 variants support and configuration (#371)

Fixed

• fixed missing UART RX PULLUP configuration that caused random character input stream on noisy environments, leading to random error messages and deadlocks (#369)
• fixed RAM_ONLY_SETTINGS option that was default in v1.6.0 pre builds (#369)

µCNC v1.6.0

µCNC version 1.6.0 adds support for the RP2040 core (Raspberry Pi Pico and Pico W).
