A user on the Duet forum, called 'Sindarius' is building a gcode viewer/previewer plugin for DWC. Some features are: -It shows a marker on the tool path according to the Duet's current position (not sure how quickly this updates) - tool-path visuals for each tool (preview multi-color prints and purge towers) - A UI for the "Cancel Object" feature (if only one part in a multi-part print fails, simply cancel the affected part) - Previews for CNC/machining tool paths (this might be useful for getting an ASMBL preview, but I haven't tried it out) Github: https://github.com/Sindarius/DWC_GCodeViewer_Plugin Duet Thread: https://forum.duet3d.com/topic/11907/3d-gcode-viewer-integrated-with-dwc/204
