I've been a bit busy lately and mainly working on other people's projects, so I haven't had a lot to post lately, but I have been working on the R3 (RepRap Router) again. My laser-strap prototype has taken up residence in the new CNC room at Hamerspace and is now sporting new endstops and tool mounts including a boom for its powerful little flex shaft spindle. I got in a quick test of the tool mount and spindle last meeting and grabbed some video:
Here's some additional pics:
Next on my list of stuff I need to do for this prototype is to get the hold down system in place and mill the sacrificial top flat. I plan on embedding some extruded aluminum T-slot that works with 1/4" hex bots into the MDF work surface like the bigger CNC setup at the space and using standard woodworking hold down clamps for now and maybe design some milled or 3D printed ones as the project progresses.
