You never know when something can go wrong. I was running full depth along 5/8" (15.875mm) 6061 at a 1mm step over with a 3/8" Tas Rougher at 12k rpm at 1000mm/min when nearly half of the spindle clamping area snapped. This pulled the spindle down into my bed a bit. I'll work on breaking it apart tomorrow. I did see this particular design as flawed, but didn't think it would actually be an issue. With that said, I had already designed a replacement with a much better clamping setup months ago, but never made it as I don't have a printer. A buddy of mine will be making it for me.
This was PLA+. I don't like the idea either, but it's the best route for the time being. My z axis plate has five rows of bolt holes spaced at 20mm increments to account for this in the future. Like I said, design flaw, not choice of material. If designed properly to account for the material that is being used you won't have any issues. I know this thing is capable of running much more aggressively than this.
Well, good luck with that. Personally I'd rather use baltic birch plywood cutouts stacked up than rely on an extruded plastic. 3D printing is great for a lot of things. Just not that.
I think you are missing the entire point of me posting though. My point is that you never know when, where, or how something can go wrong. Just because they are somewhat autonomous does not mean they are self operable.
