Exact length (height) of the XL side extrusions?
I'm going to order 8020.net extrusions for the front corners of my XL (whether this will reduce vibration or not I'd like this for a different mounting of my Rubbermaid 21 cup filament dry boxes). I'll order them pre-drilled for anchor fasteners and install them with roll-in nuts.
Unfortunately I didn't measure these extrusions when I was assembling my XL and now it is a bit difficult to know that I have a correct measurement. Can anyone tell me the exact length of these extrusions or point to a Prusa reference that lists them? (And just to be clear, I'm talking about the vertical extrusions at the back corners and midway along the sides of the XL, the frame pieces, I obviously need to match this length in the two new extrusions I install in the front corners).
RE: Exact length (height) of the XL side extrusions?
I measured them at 400mm.
Frankly, I think you're wasting your time and money on those additions. The vibrations aren't from a lack of rigidity. Adding more frame won't do anything but increase the cost and make your XL so different as being unable to handle virtually any enclosure that's built for the XL.
I suggest forgetting about this mod. It will prove to be ineffective.
