How big a PITA will it be to replace the power switch

So Robo support gave me a new CD card image that booted up to an "Updating" screen, made the main board's yellow LED flash like mad, then rebooted into octoprint and I was able torun th z-offset wizard, bed calibration, etc, and the auto-leveling probe is happening again.

So, other than their new image renaming my printer, all looks well.

 

As opposed to the implicit backup in the form of the .bin file they sent me? I'm keeping that.

 

My R2 switch was also stuck in the ON position. Removed the board by undoing the 4 fasteners underneath. De-cabled. Cut the bad switch out with nippers, glued and soldered in a very similar rocker switch from my local VETCO electronics store ($5.50), recabled and WOW! it works!!
