I'm taking the plunge!
Going to try this one out.
I like it, Tim. It makes a lot of sense in many ways. Also, this would really be the best of both worlds where you can print with just one extruder without issues of having the other bump in to things.
All parts are on order (I actually had a lot of them as spare parts already) and looking forward to start modifying my work horse!
