Desktop size steel welded router 3 axis

[Dragonfly]

For a machine this size I'd go for the fixed gantry option.

doing miter cuts on the gantry frame is going to be a mission, unless you got a very accurate machine to cut at 45 degrees ...

agree with the rails on the plate ...

my thoughts :D

Here is how I did welding before I got those HD clamps - previous design - travel 900x400x150

Mitre cuts is no problem doesn't need to be so accurate - 89-91 deg will do as I leave the gap for welding bead.
Big problem is to keep control distortion - cooling/pulling after get cold. I bought HD clamp £45 each to keep the angle.
Heat treatment is important as well - annealing (releases tension in welding joints)

This will reduce already short travel of 320mm to 220mm. Was considering that as is much simpler build
