Circuit I have no machine! it's stripped for a complete makeover...
The RepStrap makeover uses more MCS Aluminium framework.
And Ballscrews for the X and Y Axis.
Z Axis will be Trapezoidal lead-screw or just M8 rod to start with.
I also invested in a Fury3 Chop-Saw for Christmas, this can cut Steel, Aluminium and Wood with one blade - Nice!
Some off-the-shelf Internal R/A fittings and also external brackets will be used this time instead of R/A cut Aluminium.
It's easy to cut, drill and fix together with T-nuts and bolts.
And the last things I printed with Repstrap V1 before taking it apart included a load of Extruder parts, including these nice Herringbone Gears by Rhys Jones -Here > Thingiverse - Rhys Jones Herringbone
Quite a few people have done work on Herringbone gears, Forrest Higgs has a nice post here about them Here > -Forrest Higgs (Herringbone Rack and Pinion) -
Forrest's RepRap Blog is here -http://technocraticanarchist.blogspot.com/
These parts will hopefully get me printing again if the V2 RepStrap does not go to plan...
This is the point I should have made a 3D model of my new machine, but I have a whole load of Ideas that may or may not work and I always find it better to evolve as I go.
I'm going to start cutting Aluminium later, hopefully I will have something to post in the next few days, and I'll try to get up a list of what I'm planning to achieve with this new design.
Onwards - >
