Filament sensor not working when printing via USB [NO-BUG]
thomas41587 opened this issue · comments
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:
- Start printer
- Start a print via Octoprint
- Cut the filament so there is no filament within the sensor
Expected behavior
The print pauses
Printer (please complete the following information):
- Firmware version: latest precompiled from this repository
- Printing method OctoPrint
- Model Mega

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.
I have not tested this however.
