Good idea Rick. I think we would need more information about the application to make any real recommendations.
How about using a pneumatic actuator? I think that would be easier.
"My goal right now is to be able to print circuits inside of 3D models." <- Holy Grail of 3D Printing right there I can't wait till we get...
Yep. Solid wheels work best.
Duane - Check out SlideRap. I think the slider idea could work well for light load situations. I've got a piece of delrin I may experiment with....
Hawkhost for me. They're the best I've found for basic shared hosting. Unlimited add-on domains and mysql databases on even their cheapest...
Good thoughts Ed and Ag. The beaglebone is a sweet piece of kit. Should be the perfect "heart" for cnc controller. I just couldn't find the...
Yeah, I bet you can rig something up to hold it in place. The engraving won't generate a whole lot of force. A fourth axis would turn the piece...
Turn it first, then engrave?
You would think. The single axis should be pretty simple. A bit more effort in the interface and you would have something really useful. I'd...
The title made me think of something else before I read the thread. An automatic end-stop for a table saw would be a neat build for v-rail....
That's pretty cool. Do you lube the sliders at all? I guess I would expect them to bind and jump a bit.
Those are good ambitions. Height is probably less important, but could be reduced with a belt transition like I did here:...
Thanks guys. I'll try to get a sketchup model together when I have time. The steppers are a bit hidden. I tried to arrange them in the best way...
I'm making my first cuts with this machine and getting everything tuned up. I figured I should snap a picture while it wasn't covered in acrylic...
andrew published a new build: This small desktop machine is built inside a 300mm cube of 20mm extrusion. Work area is 14cm by 14cm. I used 400...
steelspinner - Great post! The rating on these things can be confusing even for someone with a background in motor operation and theory. To make...
I really the design of your x-axis. It looks quite strong, and the stepper/belt placement was clever. Nice build!
I considered a few of these options and went with the TinyG. It took a few hours to find the right combination of firmware and tgfx build and set...
Yeah, vertical is the worst case. It will carry more at an incline, and even more when level. Exact figures for that involve some trigonometry...
