    tram lines

    Hi all,
    Long time owner and lurker on the forum. I'm noticing more and more this issue - tram lines around text. Weirdly, it only happens around the text and not an open field. I take it this is a...

    Depends on what you're using it for. Those look like trail markers: how do you intend to fill the reliefs? Primed properly any paint should "rout" as easily as the next. I'm not a fan of latex for...

    http://tamartedesign.com/?page_id=26 Everything but the simulated sandblasted sign and the small roundels is Duna. The 'sandblasted' sign is 3 layers of 1" PVC.

    Duna is far superior to SignFoam IMHO. Mills nicer, less "sandy".

    PrismCarve cutout

    Hi all,
    Been many years since I've been on the forum. Business slowly died off for the ShopBot for signmaking (business shifted elsewhere for graphics), but I wanted to get back into playing with...

    Mine does that quite a bit. I think it's a combination of stuff in the threads of the rack, the carriage being not quite square (check to see that all your v-rollers are actually on the rails) and in...

    For some reason I think that input burned out Brady. It hasn't worked in quite a while. Eyeballing it is a little easier and somewhat faster for me anyway :-) I really need to update the system at...

    Ok, I think it's purely user error. I just checked my Z zero - where it actually takes the Z point - and it was set to the table and not the material surface. The material I'm cutting is 1" thick, so...

    Z axis command all by it's own!

    Hi all,
    I'm not on here much. Had my PRT for probably 15 years now and really haven't had any issue. But I don't use it much, either. Of course, now I have a job in house that I have to cut quite a...

    Unit values are fine. Dust in both computers is a definite. Taking them apart and blowing the particles out is on the schedule for the next week!

    Thanks Dave. I'm pretty obsessive about keeping the rollers clean. I cut quite a bit of pvc and hdu, both high-static items. The rails are pretty good. Might could do a quick run with the rasp, but...

    Phil,
    Azek is denser than most PVC's and will rout wonderfully. That said, even at 1" thick, depending on what the surface color is, will warp. Sometimes badly. It warps because you're removing the...

    Hi folks,
    Not a regular on the boards here, but ran into an interesting issue today. My PRT96 has been cutting relatively well for years (mainly, after Brady stopped by to help me tune it up a...

    Machining plex isn't hard, you just need a single straight flute and run it at a fairly slow forward speed, if the plex is thin. For mounting, I can almost guarantee, based on your photo, that there...

    Thickness will tell you everything. It's more than likely Signfoam or a variation of HDU. Surface preparation is everything - do it right and it'll look like a piece of artwork. My carved stuff isn't...

    If you insist on using an 1/8" bit, slow it down and use a climb cut. Like the others say, deflection seems to be the issue. Personally, I'd just mill it with a 3/16" and not worry about having to...

    Not much you can do. Try a quick pass with a blow torch to melt some of them back; sometimes with that you can just run your finger over 'em when they're cool and take them right off.
