Trying to figure out how to drill the hole for the Eustathios but just laying it out it seems rather different to this image. If I use 80mm based on the BOM for spider v2 the gap highlighted green is almost non-existent. Is there a drill guide for the extrusion bolting for Eustathios or a list of drill measurements? Is the 80mm centre to centre of the cross extrusion (from top one to support one)?
I ordered the misumi drilled parts and the holes are at 470mm from the bottom. So 562-470 = 92mm from top to the middle of the extrusion.
Ah ok, I was measure 80mm from the top assuming the Misumi measurement started top down. Makes much more sense now. Thanks
I printed a drill guide: https://plus.google.com/111479474271942341508/posts/7wMEKzx9aw6
I added 3mm because I did not use end caps. With the drill guide, it’s easy to have the holes alligned. Measurements are in the thread.
Wow, thats amazing. I am even using the same extrusions as you ( because Misumi Europe suck 
)
That will help loads.
