Filament sensor not working when printing via USB [NO-BUG] #96

Closed thomas41587 closed 4 years ago

thomas41587 commented 4 years ago

Describe the bug When the filament is empty, the TFT display reports that the filament sensor detected no filament. But the print just continues like before. I do not get any notification or similar in Octoprint. I am not sure if thisfeature is only limited to USB-printing or maybe I missed a configuration thing within Octoprint itself.

To Reproduce Steps to reproduce the behavior:

  1. Start printer
  2. Start a print via Octoprint
  3. Cut the filament so there is no filament within the sensor

Expected behavior The print pauses

Printer (please complete the following information):

Please make sure to use a search engine or read through previously closed issues before reporting a bug here.

This is not a bug, the filament sensor simply cannot stop the print if you use a USB host. You could connect it to the Raspberry'S GPIO pins and use a plugin for OctoPrint, then the sensor would be able to interrupt the print.

@davidramiro I think this is incorrect, after doing some research I found this discussion that states you need to uncomment the lines for ACTION_ON_PAUSE and ACTION_ON_RESUME in configuration_adv.h to send the M118 A action:pause for this to work.

https://community.octoprint.org/t/octoprint-windows-pause-octoprint-when-printer-sends-m600-command/13067/3

I have not tested this however.
