Thanks for the reply. I upgraded to the MK5 and now find that I can lay down a 3 x 3 raft and get about 30 secs into a build and the extrusion stops - tearing down the extruder tonight to examine for blockage. Thanks again. I like your design but perhaps would consider reconfiguring the motor mount to hide one bolt behind the gear enough to access bolt head thru a hole in the gear. If I can get printing again, I would look forward to a build of your design - good job!
