If you have a Basic machine you’ll want to watch the temperature range…the machine will pause if the unit starts to get too warm, and it can take several hours for the tube to cool off enough to restart if the room is warm. (That’s a safety feature designed into the machine to protect the tube.) If that happens, you might see a “Cooling” notice next to the Print button on the app screen.
There are some suggestions for cooling things off here:
(Unfortunately, opening the lid will kill the print, so I’d start with aiming a fan at the outside on the right first. Or if you can modify your design to take it in sections with different colors, and give the machine about ten minutes to cool between sections with the lid open, you might wind up spending less time overall waiting.)
