Yes, I wanted to give a heads up about this because it will catch some people by surprise otherwise.
Right now, units are allowed to operate when the coolant is beyond recommended limits and right up to the “do not exceed” temperature. They only react when the coolant is at critical levels, and then they kill the print.
We’ll be adding safeguards so they pause when the coolant is out of the recommended range, then seamlessly restart. Basically, prints in hot air just take longer. We’ll also add a sanity check at the start - if ambient temp is too high, we know the coolant can’t cool enough, and it won’t start until it’s somewhere cooler.
In practice, we’ve seen no pauses at the office (~70F ambient) over even long prints, but if you blow warm air into the intake, it will alternate between printing and pausing.
The functionality (pause/resume) works great; right now, we’re analyzing sensor data plus discussing with our tube vendor to figure out the right limits.
