I am sure this has been thought of, conceived, tried; but I am gluten for punishment.
I want to build an “all in one”.
A gantry I have recently built is pretty large. Dual Y motors, single X, Z controlled at the head. So pretty much run of the mill (pun intended) cnc mill, plasma cutter, laser cutter.
I want to be able to put all these things plus an extruder and a blast head on it. Yep love a challenge.
So talk me out of this, off this cliff. Challenges I am aware of.
Stepper motors: I need to go with something with umph. I believe the heaviest load would be the mill head, I don’t want to use a dremel. I want to place a Dewalt motor (heavy) on it.
Deflection: I currently have open builds 20x40 running across the X. I had to use 80/20s second moment of inertia on their 20x40 to calculate, open builds does not have this information, but should be similar. This would suffice for all things but the mill head.
And the creme de la creme of challenges all in one software: so I can finagle a marlin/repetier/slic3r-cura to do almost all things… Additive and removal, but not without major firmware changes every head change. I can play with a grbl/Chilipepper for all things but the plastic extrusion, I think.
Tell me other design challenges, why not to take this design on.
This would be for my own amusement, not looking for speed, but accuracy and precision.
