Who says we're guessing? The scientific method is what we're doing. We conduct experiments, publish our findings, and then reproduce the work of...
Yeah I just cut aluminum with my settings I used on acrylic. 20ipm is a little fast for me because I haven't completed the spindle yet but I would...
That's almost identical to my routy except my leadscrew is behind the v-slot rather than through it. The problem with mine is that it loses a lot...
Sorry to butt in, but I think it may be possible to make a large-format OX using the 1500mm v-slot and then put the rollers on simply by sliding...
This is the same for all v-slot builds, basically. So there's a little bending that happens in the aluminum Y gantry plates. There's a little flex...
Another option is to use C-clips... you can use a hacksaw to cut a groove into the shaft while it's spinning and then throw a c-clip on it.
I don't know. I think everything is done in GCode. There's a program called Skeinforge that is used to do both CNC and 3D printing gcode...
RE #2 I've found that a combination of the routy design which allows you to adjust the height of the gantry, plus mounting the spindle to v-slot,...
No that should work. I don't have a dremel so I used the 890kv motor to make the 890kv spindle. Lots of people just use dremels but they have bad...
True. I think the key factor here is the belt drives rather than threaded rod. There are other threads trying to make a rack and pinion, belt-rack...
yeah that's a big factor. People who already have a cnc will not need it. People who don't have a cnc won't be able to make it. It's like a catch...
Yeah dude I totally hear you. My machine just became very dangerous because of the speeds it runs at. I overclocked my board to 400kHz and now it...
hey that would be neat if you could slide the whole roller assembly into an OX and bolt it onto the v-slot
You can make this go as fast as you want. There is an upper limit for cutting speeds that applies to all machines. A cool think about the...
3D printers and CNC machines have identical components with the exception of the router/print head. If you can run GCode you can do CNC. The best...
well u know I have a joystick controller for the CNC so it's much easier than the drill press ;)
So my drill press is mostly obsoleted by my cnc machine. I might use it 1 out of every 365 days each year. So I was looking at recycling the...
Yes please do send it. I had read about the power up sequence and it would save me a great deal of time to start with a board that "just works"....
Anyway, I think Robert's single-axis board would be most useful to me because I already have the TB6560 chips which are awesome if setup right. I...
You have to factor in the costs of the following: Reverse-engineering the board Replacing the fake Chinese components with OEM parts Redesigning...
