MK-X Beta Stage V.3

A few updates, been away designing and printing some prototypes:

This is optional base extension. It goes underneath the main frame and gives another 60mm of height so that all of your electronics can fit + storage of allen wrenches and what not. The circle is for wiring which is concealed by insulation and the mount has a hole in the center( hard to see because it's white) that you can feed the wires out of.

This is the MK-X frame extension mount, It adds 40mm on either side for insulation and just a bit of extra space for those who have plates that extend just slightly beyond the extrusions. It also has mounting holes and magnetic slots on the other side for the metal plate exterior that can be taken off quickly to access wiring.

Here they are stacked:

The accompanying top piece:

It also has an optional mount for the top frame extension for more electronics etc.

Extruder:

This is a slightly modified Airtripper for short mounting holes, you'll see why shortly. Still working on the dual hobbed , coming soon..... Derived from http://www.thingiverse.com/thing:731585

This is the Floating extruder base (slightly old design, there has been significant new design changes within the past hour). It has a top piece as well, but I didn't print it yet. It's designed so that it is oriented short side is facing you and has minimal amount of bowden bending for the kraken. I haven't installed it yet, but my rough guess, the bowden tube from the top of the heatsink to the E3DV6 bowden couplers is around 100mm. All wiring and watercooling tubes fit through the center. It is also designed to house 4 flat watercooling blocks if you see fit.

Pan and Tilt Camera

Pan and tilt camera, uses 2 micro servos and the top piece mounts to the X-brace with 1 M5 screw. Side panel for second servo not shown. Derived from http://makezine.com/projects/raspberry-eye-remote-servo-cam/

Next update: PEI bed and X-Brace mounts

 

Here's the X-Brace center connector. I designed it to be split in half for ease of printing and installation. It allows you to have some leeway in the installation of the extrusions, so you don't have to painstakingly get them equal the very first time as you can adjust it to fit the printer's extrusions. it takes 16 M4 10mm screws - same as the ones for the robotdigg alum corners ( Trying to minimize the # of different nuts and bolts required.) It also has 2 M5 screw holes for a tighter compression of the braces ( not necessary), but really it's more for additional screw mounts for tool holders and the pan and tilt camera. 

Also started on my PEI bed today!
