Prevent computer sleep while plotting

[reidab]

I hit an issue the other night where a plot stopped with the pen down and bled a bit of ink out when my computer went to sleep. While it's easy enough to just turn off sleep on the computer driving the plotter, it would be nice to have the driver hold a wake lock while plotting is active.

This seems possible from python using https://github.com/np-8/wakepy, or by making similar calls directly.

Interesting; I haven't seen that before.

If it's a Windows PC, I've used Caffeine before (https://zhornsoftware.co.uk/caffeine/) which works great. Just run it and it will make little keypresses to keys that don't exist (configurable) to keep your computer awake indefinitely. We use it at work when we need to run 3 day long tests and the IT departments forces a 30 minute sleep timeout.
