This may not be the place to post this. I will move this if so. I know machines like this exist but I have not the money. I cut extruded aluminum a lot. I want to build a cnc back stop. It would be cool to just type in a length and have it move. I own a tiny shop that specializes in aluminum welding/fabrication. I can build whatever is necessary. I even want to build a cnc "turret" to change the angle of my saw. I know i need to learn a lot about CNC. I guess im just fishing for thoughts on how you guys (the pros) would do it. It would be nice to put up to a 24' stick in take a sliver off the end and "Zero" then type in a length, it moves, i cut. then either type in a new number or have a repeat button. I would also like back and forth buttons to move it manually. Any ideas on how i can make this happen. Is there a way to have a user interface like that (like a cnc shear)?
