Re: Opening up y axis.

I noticed flipping the spindle to the other side. Just don't think it'll help much. It moves the spindle 20mm closer to the pivot point (where rails meet v-wheels). And that only helps counter vertical forces (gravity and plunge cuts/drilling). I don't want to discourage you. It would be very intere...

Re: Opening up y axis.

I'd be worried that the Z axis wouldn't be rigid enough. Extending the Z like that makes it act like a lever. It could only take a fraction of the side cutting forces. You'd need to slow down feed rate a lot. Then you'd need to slow down the spindle to match. Dremels lose most of their power when sl...

Re: GCode Sender (Linux)

@AtomSoft Take a look at distcc. It distributes compiling across other nodes. You'll need to setup a crosscompiler in a vm but then all dev can happen on the xm. I used it for powerpc stuff 7-8 years ago.

Re: GCode Sender (Linux)

grbl has cli senders in the script directory. They're python based.

@AtomSoft In what way is the Beagleboard XM too slow? What distro are you running on it? Wanna sell it?

Re: Stepping down voltage?

I would NOT recommend following the suggestions on the link DevinTX provided. The current consumed by a DC brushed motor will vary widely based on the load placed on it. As the current changes, the voltage drop across the resistors will vary as well. I assume you're going to take your Speedsaw apart...

Re: Forum...

Maybe a forum for endmill discussion. One for materials (HDPE, UHMW, arcylic) too.

Ok. I should have specified max speed earlier.

They work. I did the last two steps by hand but they should be fine.
