What is the problem?
-
When the SD card file is printed by octoprint, the status is normal when the pause button is clicked, and then when the Cancel button is clicked, the octoprint service loses its response, so I can't get the follow-up status. I found the document that I could not click the paused button in octoprint. I needed to click the paused button on the printer. So I went to click the paused button on the printer. At this time, octoprint got the status of Printing from SD, while the printer status was print paused. After I stopped printing on the printer, the octoprint status was still Printing from SD.
-
Similarly, when my printer connects to octoprint and chooses to print the file, I cancel the printing task directly on the printer, at which time octoprint still gets the state Printing from SD and cannot get the correct state Operational. When I disconnect the printer and reconnect, the printer state becomes Operational.
What should I do with these situations?How can I get the correct state from octoprint.
What did you already try to solve it?
I can only restart the octoprint service
