The
First Batch of part drawings will be for the "625" cube then
I'll re-dimension for the rest
The
"Motion Module" is the first in a series of specialized machines that
will give cubes the ability to make the parts for a whole range of
added functions.
This initial design is for a 3-Axis, "gantry-style" milling machine.
Clearly, due to the materials used, it is very light duty.
But for a CNC this is not necessarily a detriment, since repetitive
light cuts can be made, under program control.
Therefore, it should still be possible to get substantial useful duty
out of the machine regardless of its capacity.
This is the first of the two "universal machines": A mill and a lathe.
Keep
in mind, these designs can and will be modified, revised and upgraded
as better implementation ideas are discovered or submitted.

I
have linked to Fastenal for the screws, bolts & nuts, since
they
list cross reference info to multiple international standards for
hardware.
The four "Series" are derived from the four likeliest methods of
construction
"610" is a 600mm cube made with 1 inch T-Slot extrusion
"615" is a 600mm cube made with 1.5 inch T-Slot extrusion
"625" is a 600mm cube made with 25mm T-Slot extrusion
"640" is a 600mm cube made with 40mm T-Slot extrusion
The aim is to place minimal limitations on what material can be used,
while still ensuring inter-operability between designs
