450x300 Aluminium extrusion build from scrap/used parts

[Nealieboyee]

Hi Nealieboyee,

Good to see you going for a build.
Like me i think you will like building a machine your self.

Things i see that a lot of people do different.

Move the horizontal rails on gantry to top and bottom of the profile instead of front side.

The downside is that it will raise the height of the machine some 5cm


Move the vertical rails to the moving part of the Zaxis.

These changes will be more rigid and the spindle moves closer to the gantry


Please take a look at the routercnc mk3 and the Davek build.


Would end plates connecting the base plate to the Xaxis, to get the Xaxis profiles a little more rigid, be a good idea?

Thank you for your kind words :) I've moved the x axis linear rails to the top of the gantry as suggested. I've also rotated the base plate to give me more usable space in the x direction. If I can find a bigger base plate I may use that, or even welding a steel frame....We'll see soon.
I've also added bracing from the y axis rails to the base plate. Do you think it would really help on the x axis too? Those braces also serve as the new plates for the bearing supports for the ballscrews.

As for the z axis, I've moved the linear rails to the moving part of the axis and added side supports to give a bit more strength.
Anything else that jumps out at you?
