Depending on the B parameter of the M667 command, this could result in spurious "Intermediate position unreachable" errors, or non-extruding G1 moves being turned into G0 moves. +- A badly-formed GCode file that returned the layer height or object height as nan or inf caused DWC to disconnect because of a JSON parse failure +- M579 scale factors were not applied correctly to G2 and G3 arc moves +- M119 crashed if an axis had no endstop + +RepRapFirmware 3.0beta12 +======================== +Recommended compatible firmware: +- Duet Web Control 2.0.4 +- DuetWiFiServer 1.23 +- DuetSoftwareFramework 1.1.0.5 + +Feature changes since beta 11: +- Duet 3 0.6 and 1.0: pin io8.out is no longer PWM-capable because of a resource clash. If you have connected a BLTouch to IO8, please move it to IO7 and adjust config.g accordingly. +- Duet 3 all revisions: improved the temperature reading accuracy at low temperatures for thermistors connected to the main board (typically it used to read several degrees low) +- Duet 3 all revisions: M308 L and H parameters are supported for thermistors and PT1000 sensors connected to the main board. They should only be used if you have suitable fixed resistors to use for calibration. +- DHT sensors are now supported (thanks wilriker) +- M115 P parameter is now only implemented on those builds that support multiple board types, and only when running config.g at startup +- M500 now accepts optional P10 parameter to force it to save the G10 tool offsets (thanks wilriker).

To guard against this, always enable CRC checking in DWC 2.0.4. +- Extruder stall detection (G1 H1 E moves) is not implemented +- Stall detection endstops don't work properly if you home multiple aes at the same time |
