If you don’t find a place to do it, you could try the free version of David 3d scanner. It’s more limited then the Pro version (~$430) one but it’d probably work in a pinch.
It outputs to stl, obj, and ply.
It’s possible to run Sketchup on Linux using Wine. I have no idea how stable it is but both Wine and Sketchup are free.
Grumpygeek’s CNC uses a Ridgid R2400 and he was considering a DeWalt 660.
20,000 – 30,000 RPM.
6amp
1/4″ collet.
$100 on Home Depot.
3lbs, roughly 3 times as heavy as a Dremel 300.
30,000 max RPM, no indication of having a speed dial.
5amp
1/8″ and 1/4″ collet.
$60 on Home Depot!
3.2lbs.
Thanks for the information Chris! I was thinking of linear bearing blocks too after seeing it in Sly’s build. Sly used VXB, which looks like a good choice.
Right now I’m trying to contact VXB in regards to some measurements for the 12mm bearing blocks because the Rhino model I built from the listed measurements looks like a flattened version of the actual bearing block. If I’m reading the measurements on that page correctly, the block should be 28mm tall and 42mm wide. Thus the height should be 2/3 of the width but the photos don’t convey those proportions.
I’m emailing VXB about the dimensions and hoping to have a reply soon. Hopefully I did something stupid and that the listed dimensions are right (instead of me being right and being therefore unable to trust any of the measurements given on the site).
On a tangent, I am currently planning on making a highly modified LIL CNC. I’d like to include stepper motor dampers to increase IPM, an Arduino replacement for serial ports, a dust shoe, a cyclone dust trap.
In addition I’m planning on switching out the timing belts for leadscrews or racks & pinion. I feel like I’d end up screwing up the timing belts by tightening them to different tensions. I will update you on design modifications as I make them.
Is there anything to hold the Z-Rail bearing assemblies to the Z-Sled besides a tight fit? I see that the X-Rail bearing assemblies are bracketed in place by trap and tensioner panels but there doesn’t appear to be any for the Z or Y axis.
Also a related question: why do the Y-Rail bearing assemblies stick out so far from the Vertical Braces?
Can I also reduce the width of the Z-Sled?Nevermind I see that the space is needed for the interlocking t-bolt joints.
