in process of a cnc 4x8 lowrider2 table this machine uses 5 motors on a ramps arduino 2560 combo. would like to make this system with interchangeable heads or functions. any suggestions on adding this to my system. would like to do large scale airbrush with it as well. open to ideas to make this happen.
Hi there Mark!
If I'm not wrong, 2560 have 5 places for stepper motor drivers. For this project as it is now, you will need one stepper motor to control quantity of paint. so I hope some of your X or Z steppers are controlled with same driver. Anyway you could fix the Z distance by hand and use the Z stepper to control the quantity of paint...
My actual CNC, "CoNChi" uses 2 motors for X, 1 for Y and 1 for Z. I made it previous to 3dprinting era, so it's made of DM wood and aluminum and skater bearings by hand.
I can just tell you about my "tooling" trayectory for my CNC... first I engarved and cutted wood with big spindle, then with dremmel, then I cutted 3mm aluminum plaque... After that I attached a 3dprinting extruder to my CNC and made my first prints... then finally I attached the airbrush...
You are facing a really big adventure! I hope you have as fun as I did and learn a lot by the way :)
Welcome to the group!
