[dc42]

On behalf of the Duet3D team I am pleased to announce the availability of software 3.6.0-beta.4. This is mostly a bugfix release but includes a few new features such as experimental support for WebRTC streams in DWC, experimental support for using scanning probes in touch mode, and string functions in GCode expressions.

Users of Duet in standalone mode can find the files at https://github.com/Duet3D/RepRapFirmware/releases/tag/3.6.0-beta.4. Users running in SBC mode should update from the unstable feed of the package server.

Works great for me. Solved 2 problems I was having with 3.5.2, both seem related to synchronization of an extruder on an expansion board. See https://forum.duet3d.com/topic/37435/extrusion-gaps-after-arcs for one of the problems and my config.g for reference on what features I tested.

The other problem was sharp corners looked like they had too much pressure advance, even though I was using 0 pressure advance. They were under-extruded going into the corner (while the printer was decelerating), and then over-extruded after the corner. I had assumed it was due to the huge SuperVolcano hotend, but upgrading to 3.6.0-beta.4 fixed it.
