multiple printers on 2 pi

[summer seal]

I'm probobly missing something obvious. I have 3 printers on one pi, just added a 4th printer on its own pi. If I start one and log into mainsail then start the other I can add all 4 printers and switch between them. If I turn on both pi then try to log in the browser tells me the site is not available. The pi have differnt ip addresses, different host names and different Mac addresses. I should be able to connect to at least one shouldn't I? #NoLogsNeeded

So you can only access Mainsail if you turn on one of the pis? Or what exactly do you want to say?
Or do you mean starting both at the same time ends up in no mainsail?

Where is Maisnail installed? On both pis once?
