µCNC v1.4.6

Version 1.4.6 adds the followin changes:

Added

• added software I2C (bit-banging) (#215)
• removed encoders dependency of modules. Stepper encoders and regular encoders reset is now independent (#216)
• encoders counting pulse and direction can be inverted via setting $8 and $9 (#216)
• modified settings initialization code. Added option to hase settings on RAM only (volatile) (#217)
• added option to store G92 offset in non volatile memory to prevent undesired wear (#221)

Changed

• module system complete restructure. Core complementary modules kept in the core code. Remaining modules pulled to a different repository (#215)
• encoders initial state aquired at startup to prevent initial noise counts (#216)
• fixed dir mask detection for ENC0 and ENC1 (#216)
• moved the mod_cnc_dotasks_hook callback to allow it to work even if hold is active (#218)

µCNC v1.4.5

µCNC version 1.4.5 changes are listed below.
Next release will will have some extensive changes in µCNC modules to make it more easy to add an use modules in a need only basis.

Added

Changed

• option to enable self-squaring and dual-drive axis is now independent (#208)
• option to disable homing on each individual axis (#209)
• modified encoder to make it and independent module. This work a bit like a core functionality and not a module. (#213)
• stepper encoders now report directly the position via the interpolator (#213)
• added example of mirror RAMPS board (with encoders) (#213)
• redesigned limit/control/inputs switch logic. All logic is now performed inside the respective mcu callbacks (#212)

Fixed

• EIMSK not being set on AVR MCU making external Interrupt pins not to trigger (#213)
• fixed ISR mask evaluation that prevented the correct ISR to catch the call leading to fault reset (introduced with #213) (#214)
