I really don't see true GT3 belts as an option. Belts are scarce and I doubt you will find any sources for the pulleys. As far as 3mm GT2 belts...
Are you sure you're actually looking for GT3 belts? What is referenced in the store as GT3 belts and pulleys are really 3mm pitch GT2 belts and...
As for a source, you might check with Automation Technologies to see if they'll ship your direction. G540 with resistors / G540 without. (You...
Take a closer look at how they were done in the link. All those problems were solved. He drilled out stock hex nuts and pounded stock dowels...
The easiest solution would be to make your own. DIY Eccentric Spacers for less than 40c each (link originally posted by @jzhvymetal in DIY...
Just be careful that big of a motor hanging off the end of the gantry doesn't tip the machine up on its side. ;) [sarcasm off]
Andrew, the images didn't come through. Try drag & drop with the files.
Hard to say. The stepper will lift the load but I have a feeling you'll over stress the wheels.
You're mixing two different concepts here. The torque caused by the load at the end of the beam is resolved by the gantry wheels locked into the...
Out of all the Openbuilds parts, that internal shim is pretty much the only "gotcha" I can think of. And admittedly, it got me first time around too.
There are more drawings but unfortunately there is no central repository for them. That drawing actually came from the parts store page which is...
Issue #2 sounds like you didn't put the shim inside the wheel between the bearings. [IMG] For issue #1, did you put a shim just underneath the...
It might be more efficient to break the underside of the table into a series of zones with shut off valves for each of the zones. You wouldn't...
Drill out with a 3/16" bit and let the screws form their own threads. So much easier (it takes just seconds) and you'll find the threads have a...
Metal wheels will wear down aluminum track and thus must be used with something more durable. Truly the question is how do you plan to use them...
Revised the photos. Let me know if you still can't see them.
I'm not supposed to be mentioning this just yet as its not quite public knowledge but there's a new plate that will be hitting the shop in the...
@Rigga11, If you're cutting your own plates, make them about 3" taller and move the upper set of Z-axis wheels up as far as you can. The short...
That's a good question to which I don't have a good answer. You might try scanning through the build section for ones built with leadscrews. CNC...
1000mm is about the extent of their workable length. They tend to whip when they get that long. If you want to go 1500mm you'll need to go to a...
