CNC machine / 3D printer
my idea is to use a opi to control a home built combined CNC machine / 3D printer. i have yet to receive my opi mini2 so i have not been able to test whether it can send pulses to the stepper drivers fast enough.the machine is designed to switch "tools", milling spindle, 3D printing hot-end, laser for cutting/engraving.thanks! things are getting moving finally! all hardware programming is basically done, just tcp-server left. Failed to realize that i needed to attach a heat sink on the orangepi, but a few standoff pillars and it will be fine. although it has never reached soc temperatures over 45 degrees celcius so far..
A 3d printer is next on my list. Would be good to see your experience and results with this.. i have actually built the machine already, and all software for calculating tool paths and stepper timings is also done. so i am basically just (anxiously) waiting for my opie to arrive! I'd like to have the plans for the CNC.It would be nice to have one at home. the pcb got etched today! unfortunately i can only etch double sided boards in my kitchen.. when this board is finished then these pcb's will get milled instead of chemically etched
Could you share the frame design? I have everything I need electronically, but I am still looking for affordable frame. Edited by matsumo at 2015-11-4 21:02
my design is pretty different from most of those home built machines available on the internets. because the spindle motor is very heavy (especially since it is water cooled) i decided it better to have the portal/gantry bolted down instead of having it move across the table like in most designs. not only does it help with stability but also a number of other benefits. this is the 3d model of my machine.
it is constructed out of standard upe steel beams and sheet steel. in retrospect though, i should have used a higher guage sheet steel... but it works for my usage so far!
finally orange pi is here! after a month and a half in the mail! must have freighted on donkey... nice project.
please, inform us of your advances
