Re: Prototyping material

Not cheap material, but for dimensional accuracy there are dense urethane foams you can use. This has been described on this thread: http://www.shapeoko.com/forum/viewtopic.php?f=30&t=1272 and is also available from inventables: https://www.inventables.com/technologies/precision-board-plus The sourc...

Re: Website Loading Slow

I have a similar experience with the site. I have a feeling it's being run off an extra arduino from the shapeoko parts inventory. ;)

Re: V-wheels stopped by new on-rail belt clips?

It's made out of material similar to a PCB substrate, like FR4, but I don't know that actual material--just a guess. Obviously, it weakens the clip. But, how much force are people putting on their belts to get it taut?!? I folded the belt into the slots so that the teeth on top and bottom are engage...

Re: Bendy Bits... How to model and object copy from original

Are we talking a circle, but with two flat sides that the socket would sit in without being able to turn? If that's what you want, that seems to me to be a good fit for OpenSCAD. It's overkill for the problem, but pretty simple to do it as your '3D guy' suggested. For example: module sides (width) {...

Re: New Shop Sign

They are selling a square foot for twice the price, but it's twice as thick.
Oops. I was looking at the wrong item. They are selling it at about eight times the price and it's twice as thick.

Re: New Shop Sign

Looks like inventables is selling something similar. I was about to order a big board of RenShape 460 (as per the Guerrilla Guide ). It has a density of 0.7 g/cm^3. Invetables is selling Precision Board Plus , which looks like what you got IC. It's more dense than RenShape 460 (at 0.9 g/cm^3). They ...

Re: X-Axis motion

I've been trying to work up a structure for one, but not having much success --- anyone have any ideas or suggestions? Why not just start with an unorganized list and then organize it after (hopefully!) some classification becomes apparent. It could just be a table for now with columns: problem des...

Re: DW611 with Shapeoko 2

I'm using the following with my DW660 for speed control: http://www.harborfreight.com/router-speed-control-43060.html The speed controller has a limited range and I'm not sure what the trade-offs are for this product in terms of speed vs. power. I've only tried it on wood so far and only a couple of...
