RatOS minor update v2.1.1 will be released soon, and includes some hardware pin configuration changes that may affect some machines.

NOTE: Machines built using stock RatRig V-Core 4.0 and 4.1 hardware are not affected.

Please review the following potentially breaking changes carefully before upgrading machines using the affected boards. You may need to adjust machine wiring or add overrides to printer.cfg.

• Octopus Pro H723 V1.1 (control board)
  • ratrig_vaoc_led_pin has been changed from PB0 to PB10 (#141)
  • y1_enable_pin and e_heater_pin were swapped. The assignments are now y1_enable_pin=PA2, e_heater_pin=PA0 (#134)
• EBB42 Gen 2 (toolboard)
  • filament_sensor_runout_pin has been changed from PA3 to PA10 (#141)

Other control and tool boards are not affected.

Crowsnest just recently made huge changes to the way it works. This is great news, because it should be much faster and more reliable. Unfortunately, it also means that there are major breaking changes, and you'll need to do some manual steps to upgrade. When you update to V4 through the machine tab in mainsail, crowsnest will stop working until you execute the following steps.

Major moonraker config and file changes​

As you might know, a couple of weeks ago, I issued a warning about updating moonraker due to a major change that involved file restructuring, config changes and deprecations.
