Pausing a Print Overnight

Help! 

I purposedly paused a long print overnight, left the bed, and tool on low heat. Then I woke up this morning to resume printing, but I pressed resume printing on my Octopi and noticed it remained on resume, but nothing would happen. I noticed the temperature was now zero, so I went over to the printer to find a message that says "heating disabled by safety timer" and I don't know what to do now. If I hit the X button on the printer, will that resume my print or will it cancel the entire print job? Right now, Octopi just says "Resuming" but nothing happens.

the x button is reset so that will definitely clear the print.  Dont use octoprint so cant advise on the correct sequence to resume (if its at all possible even at this point).

If it were me, I'd use the Gcode command to re-set the nozzle temp via the terminal

Or maybe..

I'd then try and resume the print... 

Bear in mind I got my first 3d printer a few days ago though!

Thank you for your response. I was trying to save the print, in the end, it did not work. The only option I had was to press the X button. I had to start over, boo. What I was told by someone in the chat @ Prusa was to use the card when printing something that may require me to pause. Thanks for trying to help though! 🙂

I didn't know about these resources, thank you so much for sharing! I wish I had seen this earlier to try it. We got on with someone from Prusa who tried to help us, but we ended up printing the x button and because the bed was cold my print came off. They suggested using the card and not OCtopi when needing to pause again in the future. I will keep this in mind though, learned something new! 

Enjoy your printer, it is so much fun!

No problems!

There are Gcode commands for warming the bed up too... but if the bed has also switched off due to inactivity, its probably not a good idea to warm it and cool it and warm it again in a single print.

I often use Gcode commands during prints if I feel the printer is going too fast, or i get too much stringing etc. It's not something I'd recommend for "production" prints, but you can put commands into the terminal in octoprint to change some settings on the fly for testing.

I have a square box I print in vase mode for example, then I change nozzle temp and speeds to tune the filament for best results on a single wall.

By the way, if you print from the SD card you can pause a print and then go to sleep for hours, come back and hit resume and it works! But it is better if you do it from the SD card and not Octoprint in this case. I did two prints already that were going to take 20 hours and needed to do that to go to sleep. It worked great!
