8x4 Router build thread

[Zebethyal]

I replied to the first response shortly after it came in, but my post is still not showing after 2 days.

I appreciate that new members posts are vetted for the first few occasions, but having to wait 2 days for a post to appear is a bit much.

I agree that a shorter X in preference of a longer Y would be more rigid, and this is how it was originally designed. The idea was dropped because of the increased cost. However I have since dropped the profile sections on the Y axis so it should be cheaper again - I am mid re-design on this again to see how it looks and costs out.

I also agree about the potential flexibility of the Z axis, which also has around 400mm of travel, especially with the B/C ideas that could have all sorts of slop in them - a more stable B/C would be a lathe type design on the bed that could either use one of my trunion designs or simply be a chuck geared down to a stepper with a tailstock.

I am also going back to some homebrew versions of the 'CNC router parts' carriages and some thicker steel for them to run on 6mm instead of 3mm, still redesigning the X/Z carriage interface.

Image shows the carriages on the alternate Y axis design.
