Highly accessible vertXtruder for OB1.4
by Wired1, published
This is highly experimental at this stage :)
Uses the standard gear set for my other extruder, included here for convenience.

Yes I found the x-axis travel considerably shortened as well because of the motor position on the x-carriage. The original bowden tube carriage slipped in behind the printer frame to get the full width and the motor now fills that space. Another option would be to put the motor out the front where there are less obstacles. Next printer I build will have no upper frame :)
With this extruder on the OB1.4 I need to move the gantry for the X-carriage towards the back of the printer to be able to cover the full print area. I think the nozzle is a bit forward of the original Bowden type setup for the OB14. It should just mean shortening the diagonal struts slightly to move it back about 15- 20mm. I am going to change it on my printer this weekend.
I attached a peg to the left/motor end of the extruder with some acetone to trip the X limit switch and also reduced the size of the X-limit switch mount about about 33%. Without these changes either the extruder or the limit switch holder will jam up against the brackets and bolts for the diagonal brace, but it could just be the way I mounted the limit switch?

Print it out and hope.
Remove the support material.
Put it all together if you can.
Still unproven **very experimental** design but knock yourself out.
