Interface is great and handy and all but here is what I have been thinking as a user for improvements. Move x,y,z to zero function: Even if I raise Z before this operation, this currently moves z down then across which takes the bit through material. I think this should be changed to at last do z plunge last. Ideally IF there was any required x/y travel in the operation it would retract z to a known recent max z. Running control software via usb cable to the interface. Mostly we want it standalone but sometime we want g-code and logs, but connecting to computer on my MacBook take several attempts at booting blackbox/interface in various orders. As we are asked to remove the usb-mode jumper when installing interface, I assume the correct route is via interface. Sending files to interface. moving a usb stick around is inconvenient, would be great to have it like Octopi where a web interface allows you to upload files. Or even some private protocol where openbuilds control software can push a file over wifi.
