Even the labels aren’t really useful. People forget to erase them more often than not.
I have the same challenge, My commute is ~1/2 hour (one way) What I’m learned is that watching this category and “Issues and Requests” will give you a sense of the number that are functional and the cameras show how many folks are in the area. Those, and time of day will give you a good sense of how likely they are to be available.
I use a lot more than the printers at the space, so I have a queue of things to work through, and any print tasks I have are usually possible most trips, unless everything is broken.
The cameras are especially usable for the resin printers.
