CNC 3018 Full metal upgrades

grabcad

Decided to upgrade my CNC 3018 full metal with a neje 20W laser and needed a laser holder.To position the laser accurately I decided to install end switches.I used square inductive switches I had used before for auto leveling the print bed on my 3D printer for repeatability and accuracy.Because of the extra cables to the X and Z axis carriage I needed to install a cable chain. The cable chain is mounted on the Z axis stepper with a clamp and on the X axis frame with the 'support cable chain frame'. Enjoy the works. And be nice, if you download, you like it.If you make it, you upload a foto.The cable chain support is also the mounting for the Z axis upper limit switch.All fastening holes are for M3 bolts and nuts. please use washers and spring washers to stop the bolts from loosening from the vibrations of the spindle.
