Honestly, just an angle bracket support at midspan on the inside face of the long rails will do the trick. As for the controller, you can easily...
They’ve been redoing the menu structure so it’s probably an oversight. Easily found though with the search bar. OpenBuilds ACRO System As for...
I can see it leading to accuracy issues. Would be fairly minor so depending on the required level of accuracy this may not be an issue....
You've solved one of the two largest problems. The other would be belt sag over the 4m distance as the belt hangs below the bottom side of the...
Prayers for the OpenBuilds family. Stay safe y'all.
I'm not sure how you're separating the forward force from the back force but let's just work with the back force as a static load. That 200 pounds...
No, the kits from this site won't go anywhere near that level of force. You'll need something far more industrial. Pneumatic actuators might also...
Simple case of replacing pieces of extrusion. And one lead screw. X is definitely the way to go though. You may want to add another rib under the...
Have you had a look at the build manual posted on the files and drawings tab?...
Have you tried Inventables?
It would be beneficial if you could provide photos of where you’re starting from.
Just move them to the outside, stand them on edge and connect them like you see in LEAD CNC 1010 (40" x 40") | OpenBuilds. Couldn't be simpler....

Use your good one as a template to drill a temporary replacement. That'll get you up and running to make a proper set.
The purpose behind the two stacked X-axis beams is to reduce torsion and thus rotational flex in the X-axis caused by the weight of the spindle....
The wires should be long enough as they typically come in a stock length which you have to cut down. Something to verify with the shop though. As...
OpenBuilds ACRO 1010 40" x 40" - OpenBuilds Part Store should do the trick for you. Work area is 800 x 800 so you'd really only need to trim down...
Yes, and if you work out the lengths the shop will generally cut them for you. Just leave a note in the comment section when you order it.
It’s not about assumptions, it’s about universally accepted convention. With the exception of Bob’s CNC, everybody follows the same convention. If...
Look into constant force springs to help counter the weight being raised. This’ll take the load off the motor and make the system more responsive.
