You can buy a screw shield that plugs into your arduino which makes hooking everything up much easier. Then, follow one these diagrams (C-Beam cnc...
My z axis is 500 mm. I believe I just ordered a 500mm linear actuator from the OpenBuilds parts store. It helps to line up the x axis because it...
I use metric as well. The math is so much easier. In my mind I can picture what 0.5 mm is, my brain just can't wrap around dividing an inch into...
Wow! I fell behind on this one somehow. This build is great! I may use the drill chuck idea for a small rotary for my K40 for pens, but I think a...
This will be interesting. I will be following the progress since I am doing something similar. I am doing this: K40 12x24in rebuild (In Original...
I have no issue with Nema23s on my rotary axis CNC, but I do use a 1 to 6 gear ratio. I made this one with almost all "off the shelf"" Openbuilds...
The firmware is already loaded on it. If you are getting an error saying it is not detecting it follow troubleshooting guide in the manual....
The three flute works great for aluminum. If the aluminum is getting really warm, something is wrong. I have been cutting a lot of aluminum...
Great video to figure out your V bits true angle. [MEDIA]
Technically, I use a post processor someone wrote for a grbl based rotary which translates mm to degrees. I further modified it so it outputs the...
I just looked at the Cbeam video, and at about 1:47, the demonstration cut shows the endmill not reaching all the way to the front when the Y is...
Is there a chance the spoil board is both too large, and not centered? How large did you make yours? From the product page: Travel (Work Area)...
The longer the measurement, the more accurate you will be. Use a meter/yard stick if you have one and a really fine point V bit.
You can generate your tool paths with Aspire and save them using the OpenBuilds GRBL post processor (docs:software:vectric [OpenBuilds...
Find some scrap and give it a test. I am conservative and do 1/2 the endmill diameter for depth of cut and only go 2500 mm/min (100 IPM) for...
Mine focuses at exactly the distance of a spray paint can lid (top to bottom). That made life easy...and colorful.:thumbsup:
I did not thing of using that function.
If you do go with ball screws be careful of what pitch you select. Many people go with 1605s because for some reason they are sold everywhere....
It should unless your power supply is more than 24V, or the stepper motors for some reason are way out of the spec range for the Backbox. But...
If you are considering the $229 one the link went to, I think you would be overcharged by nearly $60 for that kit. You are getting four $10-$12...
