Version 1.20RC1

New features:
- Heater PWM frequencies are limited to 1kHz to protect
the heater mosfets
- Tool offsets and fan mapping are now passed to
DWC
- More free memory is available, especially in the Duet 0.6/0.8.5
build
- Maximum bed heaters increased to 4 for the Duet WiFi/Ethernet
-
The software reset data now records the date/time of the reset if known
and a longer stack trace
- The maximum length of GCode commands has been
increased, in particular to allow long passwords in M587 commands
Bug
fixes:
- Fixed M28/M29 file upload
- Fixed some USB/Telnet response
formats when in Marlin emulation mode
- Fixed move timing when a long
slow printing move follows a faster printing move
- Heater tuning was
not possible in 1.20RC1
- If a file being printed executed a macro right
at the start, DWC could assume that the print had already finished
