CNC Plasma | Gantry Upgrade

by Pertneer on January 9th, 2014

This version of the gantry has undergone some changes since its inception. Mostly because I didn’t foresee everything needed to make these changes before i started and had to make some more changes. Others were changed for future plans, while still retaining functionality until the other changes are made. This image is the future version it will finish in. The main difference from what I am doing now is the addition of the second linear rail on the y axis (gantry carrying axis). The other is a lower profile of the gantry itself to allow a better connection between the welded pieces and a overall aesthetics of the gantry itself.













In the image you can see that I lowered the cross member down into the side pieces to produce a better weld joint. This also allowed the linear rails to mount easier to the plate on the gantry by positioning the bolts above and below the cross member instead of drilling more holes in the tube itself. Less chance of a miss-alignment of welded pieces resulting in an uneven motion with the table. Also during the creation of the linear rail mounting plate I added two dowel pin holes to allow positioning of the plate onto the gantry to ensure accurate positioning.
