ETA Override

The best ETA in 3d printing is ETA coming from slicer software. Slicer adds M73 commands with estimations of print progress, time, time until next pause etc.

This plugin uses firmware reports issued to serial output and coming from M73 g-code commands. Supported firmware issues M73 Reports for SD-card and USB printing.

Data used by plugin:

  • time until end of printing
  • time progress reflected in OctoPrint web UI progress bar (but due to OctoPrint limitations not in API, see OctoPrint/OctoPrint#4663)

Also this plugin queries for position (M114) when every M73 command parsing happens and fires z-change event (to support sending status message every X millimeters via telegram).

Supported firmware

Supported firmware list and recognized messages.

NORMAL MODE: Percent done: 21; print time remaining in mins: 33
SILENT MODE: Percent done: 21; print time remaining in mins: 34

NORMAL MODE: Percent done: 21; print time remaining in mins: 33; Change in mins: -1
SILENT MODE: Percent done: 21; print time remaining in mins: 34; Change in mins: -1

echo:  M73 Progress: 10%; Time left: 20.0m; Change: 7m;

(each part of report is optional and configurable in Marlin 2)

Enable Marlin2 options:

  • SET_PROGRESS_MANUALLY, SET_PROGRESS_PERCENT, SET_REMAINING_TIME, SET_INTERACTION_TIME, M73_REPORT

Disable Marlin2 options:

  • M73_REPORT_SD_ONLY (disabling allows plugin usage when printing from OctoPrint over USB/serial)
