welding steel base or just getting aluminium extrusion

[reefy86]

Cant decide what i will need until i finish my gantry design and report back as the way i am going like boyan said is i may need servos which i was trying to avoid, what price range am i looking at per axis setup for servos? the hiwin rails and ball screws are whats taking up a lot but i am in no rush

edit.. just going to point out just in case someone can rescue me from over designing which eventually is going to push me to servos lol, the only thing i will be cutting is wood or up to 10mm acrylic and thats it but it does need to be a solid gantry for 3d carving. i will however want to make a small machine to mill aluminium and steel eventually :)
