Yes, the more I think about it, I see it might be too much of a hassle. I have 2 wifi and expansion board already from never realised project of a big printer I have no time to build, so I just bought two kit frames that seemed like too good to pass, but smaller in print area, so was thinking as I already have an option for that much motors, why not to try and run them both side by side, It it would have its merits, single power supply, single board, single centralised control... And half the print time. 🙂
