While I didn’t initially buy the Hemera for the Up mini, it most certainly looks like it can be a good fit. Will first install on my i3 rework and update this if I make the necessary adapter and cooling shroud
(both the change in e-steps and additional cooler will likely mean new controller, which is fine as I have a few Duet3D boards eager to get into the mini 2.)
Seemed to fit, even with the over-sized fan grill because to too long screws. Initial test show full range of motion, might even be possible to increase the travel a little with alternative firmware!
