MK-X Beta Stage V.1

Man I learned a ton of openSCAD, boy did it take long, but it's proving to be extremely useful too. Many things are turning out as I had hoped.

Here are a few updates below! 

First up, is a Cherry Pi IIIS 2nd derivative spring carriage: 

         I hate zip ties for anything other than tidying up wires for aesthetic reasons. This carriage is going to have an optional cover plate, but that's excess and will come later. I also always had trouble tightening up my belts on my Kossel and wanted a simple belt tension system where I didn't have to hold a belt extremely taut and then quickly ziptie it. This is what I'm working towards.No loops here, The belt goes through the top belt gripper, and there is a screw that travels left to right tightening the belt even further. There is almost an identical piece to the top belt gripper (not pictured), forgot it somewhere. This bottom piece has a peg that fits , snug into the slot so that it does not rotate in the XY plane (perspective looking down directly on the Z-axis from picture's pov), but can travel in the Y direction. The bottom belt also mounts in the same manner as the top. A fairly long M3 screw enters from above and goes through the bottom belt gripper into a nut insert. This way, you can easily turn the m3 screw and tighten or loosen the belt as you see fit.

Spring Effector Kraken Effector mount Alpha prototype

This one has a few kinks to work out, this is an old design, and has been edited since then. The auto-tool changer stuff is going so far back its not even on a back burner, its off in a corner cooling. Till then, Just a screw mounted hotend style. This raises the Kraken so that the block itself is flush with the bottom of the effector plate. I have V6 heater blocks which don't fit in the same manner as the V5 heater blocks so they are positioned at different angles. There are slots on either side that allow for the wiring to pass through. The effector was designed to raise the Kraken up for 2 reasons, to gain back 20mm of printing height, as well as bringing the bowden tubes higher up. I am running quad  dual-hobbed pulley extruders in a float configuration above the hotend which is pretty wide. This allows me to shorten the bowden tube as the arms widen up further up the rod allowing for clearance of the extruder setup.

MKX Crossmount

This is a 20mm tall cross mount, designed so you can stack multiple to strengthen if you want to. I only have a profile view of it, but its not flush to the extrusion. It is brought out 15mm because many people use build plates that extend past the plates and it gives me clearance so that the effector doesn't hit the cross arms. They are also M5 holes. It's designed so that it syncs up with the rest of the MK-X design, but I made it so you can just toss it onto nearly any 2020 delta for some extra strength. You just need to print 2 pieces then print 2 more but just mirrored. There is also a connector in the center of the X for extra mounting( tool change, pan and tilt cam, pick and place, etc)  Coming soon...
