Some notes on pausing the printer for several hours

I wanted to pause my printer for several hours while I was not able to monitor it, so I did the following (using an octopi):

To Pause:

1. Waited until it was starting to print the infill
2. Paused the printer
3. Noted the layer and height of the z-axis (easy to do when running octoprint)
4. Noted the bed and nozzle temps
5. Raised the Z by 10mm (optional)
6. Manually set the bed and nozzle to cool down and confirmed they reached room temp.

To resume:

1. Manually set the bed back to its' original value and allowed the temp to stabilize.
2. Manually set the nozzle back to its' original value and allowed the temp to stabilize.
3. Lowered the nozzle 10mm back and verified that it was at the correct height (only if it was raised previously)
4. Resumed the print

One gotcha was that octopi seemed to have lost track of where the z was when I went to resume.  I lowered it 10mm but it did not show up as lowered back to the starting height (17.6mm), instead it was still showing 27.6mm when the nozzle was back on the print.  I took a chance and hit resume however and it went well, and did not try to lower another 10mm further into the print.

Another thing to consider is bed adhesion since powering off the bed will sometimes cause the print to release.  Generally on my printers that does not happen and especially so when running PETG (which can stick too well).  If I think there my be some problem with that though, a brim may help if it looks like a long pause may be needed for a print.
