Haven’t decided on the business end yet. The work envelope is only 12"x12"x6", so likely an extruder or laser. Left some of the cabling long in case I expand the X and/or Y axes. I’d like to use it for it’s original intended purpose - if I can ever make space in the garage. Sorry Ryan - your outstanding design deserves better than a Fisher-Price™ color scheme, but it got what I had on hand.
