  2. By default, the Z axis rises to 1" when Stop is pressed

    Unfortunately, I don't actually have that much headroom on this particular project, so it triggers a fault, and I can't resume smoothly. Where do I change that 1" value to something lower, like .25"?...

    I've got a 72" Power stick I'd sell for half the new price. It was never used; as soon as I got my Buddy I substituted a longer Power stick for this one. It has a 60" rack; I'm not sure if that...

    Shopbottools.com was flagged as dangerous

    by Norton, the security system I use. I'm not sure what's on it that's causing these red-flag warnings, but it can't be good for business - you might check it out.

    Someone sold one last year off this board for around $3k, but it had some updates. You can probably discount yours a little for not having them. See...

    It is solid, but you're right; it's not pure tungsten carbide

    It's made by sintering grains of tungsten carbide with cobalt metal, which produces a solid material that's ground to form tools. The endmills referred to earlier in this thread are sold as "solid...

    Given that these things are not going to fit on your Shopbot in the orientation desired, if you want to use it you'll need to do them in two parts. See if all the carved detail can be contained in a...

    I clicked on the "shopbotograph" link and got warnings from my security software about malicious code on the site. It seems to have been compromised. I wouldn't advise downloading it.

    You can use carbide bits on marble, but for granite you need diamond. Most diamond bits intended for stone working require flood coolant, although some can work dry. But any time you're making dust...

    I agree with Robtown about the Photoshop work. The hard shadows are going to make this look a bit different than you might imagine, since the height-field algorithms that CAM programs use to convert...

    It might be stronger if you used threaded inserts into the HDU, instead of expecting the glue to hold the screw threads. You can glue in the inserts: https://www.ezlok.com/

    On my Buddy, the VFD doesn't power up until I hit the blue "reset" button. Is yours the same?

    Do you still need this stuff? I've had good luck with the "precision board" made by Coastal Industries http://precisionboard.com/. They'll send out free samples for you to try, which as I recall...

    Nice work, Ken! Will you have to do any sanding, or do you consider it ready to finish? I often want to do parts that require long cutting sessions like that, but I'm afraid to leave the machine...

    It depends on your workflow. If you're already working in 3D and just need a way to carve the models you've made on your indexer, then get DeskProto. If you've got a lot of basically flat reliefs or...

    Brady is right; while the "wrapping" technique can work in some cases, it's basically a kludge. If you can make a real 3D model, there are better ways to generate tool paths that will carve it. I'd...

    Thanks, Brady. The guy in that thread was a bit more ambitious than me, and added an entire new section of extrusion for a 3" boost. I just substituted a 4.5" extrusion for the top 3" one, boosting...

    I needed a little more headroom

    for my Shopbot Buddy, since I was carving 3" thick stock, and kept triggering errors when it went to its safe height. It was actually a fairly simple matter to replace the original 3 foot long 3"...
