As this is just a temporary build with the intent of using it to cut permanent metal plates I would suggest bringing the X-axis down as close to...
Not sure if it will be money well spent as I get the feeling you'll be a bit underwhelmed by it. You'll upgrade and upgrade and upgrade some more...
That may be a switched input/output if it is for higher voltage. And as to how to determine which is input and which is output I have no idea....
Actually, the best place would be on the build thread I linked to above. TrishC appears to be monitoring that thread
Has already been discussed in posts #21 & #22. OpenBuilds WorkBee 1510
You probably don't need a board that elaborate (or expensive). Google "Arduino stepper motor control" and it'll give you an idea of how simple...
A half pound would not likely be an issue on a vertical belted system. If you keep the top pulley small, say an inch or less, half the width would...
Here would be my suggestion. It's not fully detailed but there is enough there to get the idea. Mainly it is an attempt to make the best of what...
Are the base pieces OpenBuilds V-slot or just regular T-slot?
Photos of what you have would be helpful...
It can easily be calibrated using a dial indicator or a set of calipers or even using a ruler set vertically against the face but if you're using...
You only really need one and it needs to be inside the wheel, between the two bearings. As for the M3 screws, there's nothing special about them...
Make sure there's a shim installed between the bearings in the wheels. This prevents the wheels from locking up when tightened.
I'm away from home at the moment (and my main computer) so I can't provide much in the way of answers. I can say on the issue of 6mm or 1/4", it...
*Openbuilds screws are intentionally rolled smaller to eliminate the need for sanding in order to get 8mm bearings mounted on the ends.
Can you check the diameter of the lead screw to see if they got an out of spec lot? Openbuilds screws run 7.76 to 7.80mm whereas most commercially...
Success should never be contingent on luck, but rather ... on preparation. Start with your side plates attached to the lowest layer and then all...
Loctite Epoxy Metal/Concrete seems to get the best results when squeezing it down to thin layers between materials. Might be a good idea to rough...
If you want the higher torque steppers just decline the motors on the machine build page and add them from their page in the electronics section....
I would suggest bonding the two C-beams into a single square tube section. Tubular sections offer more torsional rigidity than the sum of the two...
