k40 Gantry Upgrade for linear rail
Description
K40 Gantry for linear rail. laser head is adjustable up and down, forward and back, you will most likely need a longer belt for this gantry. I did not put holes in the top for the drag chain so you can drill them to fit your drag chain. There are 2 holes in part B that you can heat set brass inserts so you can put screws in it and lock down the adjustable height. The belt locks in like the y axis belt on a Prusa, you will want to use m3 screws, there are optional slots to put nuts in the bottom is you want, but not necessary. Important: Print 2 of part C in the orientation they are it will help with the sliding up and down of the gantry. after you slide the two part c's into part A, glue them on the top and bottom. you will need a well tuned printer for these parts to fit, the tolerances are tight, you may need to sand them down a bit to fit if your printer is not well tuned.
