Chase Wichert asked me to post this here too. As mentioned here and there (@KS) before, I had the chance to collect some experience with the Rumba controller. It is a pretty reliable piece of hardware (except the USB socket on my old controller) and certainly a good choice. Nevertheless, as we have read here already a few times, there occur situations where you want to hit some sort of an emergency halt button. On my OrdBot-controller, the same LCD board is used like the one that comes with the BB. You have a choice of which housing you build there after assembling everything in more spaghetti-plate like manner. The boxes for the LCD display (you find them on Thingaverse) all have one very valuable feature - an integrated button to operate the reset switch that lives on the LCD board next to the rotary dial (incremental encoder). I am not sure how often I pressed that button in the past two years during prototyping new firmwares, new steprates, new PID configurations or just when something went not exactly als wanted. Definitely superior to a mains switch power cycle (remember you switch off the hotend's heatsink fan too then, allowing the heat from the hotend to climb up... ) in any case. So, what is the reason that the BB controller does not have a button there? - Or does it? I never read here, ' I hit the reset switch'. And I dont see one in the LCD cover. Cheers, U.
