5 years ago How does this duplicate mode work? You simply enable it with M605 S2 and the printer firmware will use every gcode command for both extruders? Does OctoPrint support this (shows the length for both extruders)? Since I don't have a dual extruder I have no experience with it.

5 years ago Yes, Enter M605 S2 and the printer firmware automatically does every gcode with both extrudes at the same time. They are typically on the same Y axis and obviously Z axis, so the X motors move in unison. It cuts the build volume in half in that direction as the heads are offset by exactly 1/2 from each other. Some youtube videos that show the setup: https://www.youtube.com/watch?v=8N4H9zN2VfE and https://www.youtube.com/watch?v=0J0Y5gtCsQ0
My printer has support for duplicate mode and mirroring mode. Basically 2 nozzles run at the same time, but the build platform is cut by the number of nozzles used (1/2 for 2).
From the G-Code, the use of duplicate mode can be detected by the M605 command, specifically M605 S2 http://marlinfw.org/docs/gcode/M605.html.
When in duplicate mode, the spools for toolheads T0 and T1 should both be used equal amounts.
