That won’t buff out. Anyway, I found that a few of the parts had shifted holes. “Hmm, maybe the giant 12 x 28″ slab of .5″ thick aluminum somehow moved… a quarter inch”. However, a quick scan with calipers later found that all<\/strong> the parts had their internal holes shifted consistently about a quarter inch. In fact, the entire profile<\/em> of the parts was shifted rightward. I didn’t notice this upon retrieving the parts from the tank because it was so consistent (and they were masked by a paper cover)<\/p>\n The machine had cut all the holes and internal cutouts, but then somehow started 1\/4″ too soon on the contiguous outline, taking with it all the parts.<\/p>\n Some of the cutouts, such as the arm spacers and small parts attached to internal cutouts, are salvageable, since they don’t rely on the top surface for placement. The arm towers, main fr0ks, and side fr0ks are a writeoff. I would actually prefer to redo the entire thing because I still have time.<\/p>\n I suspected file error, but figured the machine occasionally burps anyway. All machines do – they’re never flawless. But when it happened again<\/strong> cutting Uberclocker’s top and bottom plates… In this case, it routed a path through half the holes, the top plate profile, the last half of the holes, then the bottom plate profile. Somewhere between the “top plate profile” and “bottom plate profile”, it shifted a quarter inch right again. The bottom plate on the right is beyond reasonable recovery, since I’d have to move almost all the holes. Fortunately, I took out the top plate after it was done cutting – otherwise it would have had a quarter inch trimmed off.<\/p>\n I’m going to stop running multi-part files for now, as a sort of damage control.\u00c2\u00a0 It’ll take a bit longer to run the jobs, but the machine shouldn’t be playing any trickery. Here’s hoping it’s a one-time thing.<\/p>\n tl;dr waterjet hates charles.<\/p>\n Here’s some more pics of epic partfail.<\/p>\n The mirrored part has an equal right-shift in the profile.<\/p>\n The small internal parts are fine because they were part of an inner loop. I’ll just manually mill the corner blocks on the right. The trussed spacers are salvageable.<\/p>\n These arm towers are a total loss.<\/p>\n Hmm, a hammer might solve that.<\/p>\n Someone truly determined can probably salvage the parts, but I’d rather mooch\u00c2\u00a0 aluminum off the ML guys and recut these (I actually did buy this mirrored aluminum myself last fall)<\/p>\n Anyways, with the waterjet mad at me, all I could do was start on the parts which didn’t require it.<\/p>\n![\"\"](\"\/pics\/cb\/cb_25.jpg\")
