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 generation....
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 22....
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 openbuilds...
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 parts. I...
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...
I'm having trouble finding the 6600 on digikey. They're like $8 on ebay. So I looked around and found a 16 pin DIP chip that does 4.5A...
I still haven't decided on a chip but I do recognize the enormous price and power savings these ICs give. My first build was an h-bridge with...
So getting back to the thread, I may be making my own motor controller board based around the TB6560 using the parallel port and linuxcnc. If I...
Dude, windows is dead. Accept it. Maybe get some grief counselling. o_O. Maybe one day they'll have retro XP devices like those Atari emulators. Look...
Also XP is end-of-life in a few weeks. No more updates from Microsoft.
