Was that while the 1F was cutting a project? The controller doesn’t use much power when idling but the power need goes way up when the RPi is running a program.
Yeah, they’re hanging out there defying gravity with the weight of the cable levering the connectors. I switched them to angled connectors so the moment of inertia was minimized. It’s also why I didn’t rotate the screen - where they are, the way I built my table they aren’t in jeopardy of me knocking into them as I move around the table.
I set up a laptop stand so I can use that too, but the controller & monitor let me put the laptop back inside while a project runs. I like the versatility.
