So now why is it again you need an 8mm 16t? Does you stepper have an 8mm shaft? And if it is the 2.5 ratio that is important, robotdigg has a...
If you have a circular saw you might scan youtube for how to build a circular saw crosscut jig. They are fairly easy to knock out and would make...
8mm T8x2 Lead Screw Trapezoidal ACME w/ Anti-Backlash Nut kit 140 200 300 400
Lead screws sold in the OpenBuilds parts store are all 40 mm longer for this reason. While the nominal lengths are 250, 500, & 1000, the actual...
You will only be milling the top surface of whatever you put in there. If you've got a 2" bit you will only be milling the top 2" of the object...
A previously proposed solution for getting additional clearance used 3/8" bar stock to raise the wheels and then removed the 1/4" shims so there...
I'd suggest taking a measurement. If the metal plate is hitting both ends, that's 11.18 inches of movement.
You will also need to either shim behind the mount or do a bit of grinding on the backside of it. the nuts are 5mm deep and the space between the...
The real question here is when do you start your own build so you can write first hand? (Yes, the sound you just heard was that of a gauntlet...
Use axial thrust bearings in conjunction with the regular bearings to support the load.
I'm a bit jealous of the lumber that guy is able to get in the PNW. If (and I mean "IF") I could get clear Doug-Fir in my part of the country,...
You can get gt2 belts up to 2.2 meters from SDP/SI and 1.5 meters from Robotdigg. Other sizes have different max lengths. Just choose a screw...
The problem with using 4 separate motors is connecting them to a controller. Most controllers only have connections points for 3 to 5 steppers...
Here's one I suggested a while back. It offers depth without the loss of rigidity from dangling down a long z-axis. The basic concept uses 4...
Can't blame a guy for trying! :thumbsup:
Actually you don't, in reality you lose Y-axis cutting depth. When the cutting board is as far back as it will go on the rail you are now even...
I don't have that level of access to the system but if you will please email http://support.openbuilds.com/support/home, they will be happy to take care of it. Sorry...
Well isn't that a wee bit corrosive... :eek::eek::eek:
I can't offer a ready made solution but would suggest going with an Arduino setup. Do internet searches for "controlling Arduino with with IR...
1. One motor is fine just be aware that keeping the gantry square can be an issue. This can readily be overcome but it does take a bit of...
