There's someone in the next city over with a new roaster and he might let me play around with that some time to expand Typica's support for setting controls on the roaster. He's not interested in automation, but the machine is massively overpowered and he wants an easier way to make small adjustments. None of my machines are set up for computer control so I haven't spent much time on that.
None of the machines at work, that is. I've got a machine at home with some computer control capabilities modded on but it's a weird enough design that anything related to that isn't generally useful.
