I've made a little more progress this afternoon.


I've finished a mock assembly of the carriage. This is subject to being shortened on the height as much as the finished design will allow so that I can still get a good travel in the Z axis (up and down).








As a contingency factor I’m considering the prospect of using 4 linear rails in the X axis rather than just 2. This isn’t my first choice though as it costs more. BUT if I can get good stability without drastic effects from inertia of the carriage rapid traversing then I'll leave it with just 2. There will always be the option to upgrade to the 4 though so that will be a bonus if like said required.


Just doodled over a picture if any can can’t understand what I’m babbling on about, the square blocks are the linear bearing blocks and the “?” are the extra ones factored.








The side supports like said are subject to being shortened as much as I can with the top brace to follow suit so the set up is as pictured, just shorter.


Next thing to do will be to order some hardened rails, support brackets and linear bearings and take things from there as and when funds allow or the missus signs my pass to take over the kitchen.
