    Default Makino u3 errors

    Brand new machine. Yellow warning 2222 and a red warning about a bad EIS card and another about a 60 second macro timer reset. Anyone else have issues like these and have work around? I set up a work peice at g59 and used the auto plane correct function. I let the machine sit for a few minutes while I reset some cutting paths in my cad program. I was able to home, set g59 via corner find, auto plane correct, then the machine threw up 6 yellow and red alarms after it sat for a few minutes. I powered it down via the control and upon power up and setting the machine home the Z axis moved but the X and Y did not. The yellow 2222 and red EIS warnings are the only 2 I can not clear. Help!

    Couple of things.

    This thread should be in the EDM forum.
    More people ( myself included ) with a U3 at our disposal visiting that patch of PM land.

    Second, though I've only had to call Makino a few-three times with learning-pains, whenever I did they have responded in less than 2 hours.
    Not only that, but the fella on the other end actually knew what he was talking about.
    If you are new to the machine, might as well try and test the support they provide.

    I thought I posted that in the edm forum. And yes, makino has been pretty good. Turns out there was some bad hardware. Swapped out, new software and its cutting. EIS card was faulty from the factory.

    Yeah, I've had a flaky/DOA conductivity sensor during install as well.
    Fed-ex - Red the part, swapped the next day.
    Shiit does happen, thankfully nothing since in the 5+ years.

    Any advice on cutting cylindrical pieces? I'm taking the OD, diving it in half and using the corresponding E and D codes. However, it doesn't cut smooth. It sputters pretty bad. I did, however, cut a part today and held a tolerance of 50 millionths. I'm super excited about that. It was a relief in a gauge pin .750 along the length and .125 up from the center. Nailed it first try. I love this machine.

    My "Group" is hovering very close to pulling the trigger on U3,

    Looks like an excellent platform.

    I'm not a Wire EDM expert but have been trying to dig deep on Wire EDM related stuff for several months.

    I have about 1000 pages on different cutting conditions and parameters for the U3 that we are trying to figure out cycle times for vs various materials , passes and program design + surface finishes and geometric straightness.

    BTW good to know that Makino IS responsive to any of the usual problems with a new install - nice to know.

    @CleaverUsername1 good to know that you got some good geometric results on your pin. Almost straight out of the box. Nice !

    Sounds like you are liking the machine.

    Do you have 4th axis or the H.E.A.T option ?

    Which and what U3 do you have ? (options wise ?) U3i or U3_B ? etc.

    Feel free to throw up any sketches or pics to help illustrate what you are getting to...

    Cheers,

    U3i. The machine is amazing actually. It's a bit frustrating as I have no experience with EDM code so it's basically sink or swim. I'm able to cut stuff and put product out the door, however, I find myself editing post or reposting more than actually cutting. I'm decent at drawing stuff and selecting wire paths, but I don't know what to expect from my software. We're using bobcad v32 and it's okay, I can hit numbers and put parts out but the process of getting the NC how I want is gruelling. It also seems like the easier stuff is more challenging. I designed a wire path for cutting a stainless vise and the cleanup geometry was more difficult than cutting the actual profile. The hardest thing for me at the moment is cutting a pin. I work for a precision guage company and cutting a pin to a dimensional call out is driving me nuts! Wire breaks, shitty finishes, I cant figure it out. But a complex wire path cut I can run beautifully. One question I need answers to is how much editing do you guys do to your post once your cam software creates it? It feels like I waste a ton of time at this step. If you guys feel up to helping please feel free to email me. ZerocheckEDM at gmail. I'd appreciate advice or general conversation about wire EDM especially if you've got experience behind Makino U or bobcad.
    Thanks guys!

    I guess I'm having a bit of trouble visualizing what you mean exactly ?

    And the other thing I'm having difficulty understanding is your use of the machine ?

    That's because of my own intended uses / bubble (perhaps ?) .

    So for ME Wire EDM (will ) enable me to get to very difficult and tricky profiles that would be impossible to machine and also introduce the minimum of stress into the materials especially thin walled complex profiles.

    I understand the U3 and U3i can "digest" regular G code if you want (unlike others that have proprietary formats ) , BUT also there is a lot of on control "wizards" / doctors and canned cycles and special trouble shooting assistance on the control. I.e. iteratively trouble shoot and converge on a good set of parameters.

    I believe you can make simple cuts on the control ? (graphically ?)

    Can you post your basic wire and cutting and material conditions up there ?

    personally I'm not expecting amazeballs finishes in some cases even if I go to 5 passes in various materials AND the plan for critical / functional surfaces is to build special lapping and polishing jigs for our specific application and a specific subset of critical surfaces.

    If I had to make a cut on a precision gauge pin of some sort , I'd still be looking for an additional finishing strategy unless it was for more "dumb"/ quick in house work ? (probably someone will correct me on that).

    Can you list the wire diameter and approximate geometry or cut you are trying to make on the pin just for sh*ts and grins to see if I can actually pull up reasonable cutting parameters for the 1000 pages of data that I have (without violating proprietary info.).

    Also if you post a photo then other "Peeps" here that run the U3/U3i can tell you if that's "normal" or not ?

    What Ra and Rz are you going for / hoping for ?

    I did notice a couple of redundant / anomalous sets of parameters that did have me scratching my head a little bit to think Hmmmm did they mean that or is that a "bug" ? (just an analytical "stick out" .).

    I'm also interested in checking out what Esprit have to offer for Wire-EDM , I know its a little pricey / over specc'd perhaps but I'm kind of a fan of their development team.

    Honestly I probably won't engage at this point with emails etc. (maybe in the future), That's why "We" have a forum. :-)

    @CleaverUsername1 speaking of which , MAKINO have training for that machine ... No ? and they also have their own user portal ?

    With Makino they have a sort of emphasis on "technology transfer" so they call it but what they really mean is they hope that they provide the resources necessary to use the machinery to the best of it's intended capability ? (if needed ?).


    I was wondering if you were rotating a 4th axis too quickly ? But no 4th on your U3i.

    And the machine is brand new ? Bought as such ?

    Are you breaking the wire and using the automatic rethreading cycles ?

    Interesting that on the U3i there are a lot of features that are not 100% necessary (as the "other MTBs" have those as box checkers ) that do add some complexity, but seems on the U3i there are one or two additional features over the U3 that are supposed to be nice to have / enhanced quality). Out of the eight or so enhancements of the i over the U3_B two seem really worth while. [I know that's super vague .]. (will dig back through stuff.).

    Sorry you are having some hassles but I bet they can be straightened out, one way or another ?

    Is the software on the control fairly current is there a newer "patch" / version available ?

    OTOH if you have a "flaky" conductivity sensor ^^^ , then that quick two millisecond reaction time to stop the wire short circuiting is for naught ?

    @CleaverUsername1 maybe there's another hardware issue ?

    That's a lot of info to cover there lol... my company makes precision gauges for industry and some have dimensional call outs that I can hold with the Makino. Flats, certain lengths, relief cuts, special profiles, etc that I can already hold to within a tenth or 2. I also use it as a micro boring bar, going from .020 to .030 to whatever size I need, I just bored 2 rings this morning from a .02 hole to .0594 and nailed it. The rings get lapped by hand 3 tenths or so to a mirror finish on the ID. I can cut those types of profiles perfectly but if I ask it to run as a basic cutoff with one rough pass E 1066 D.00787 (or so, I have the E and D offsets on my desk) across a pin the machine does not cut correctly. It hisses, pops, breaks wire, does myriad clusterpucks. My biggest problem now is bobcad post processing for the Makino U3. It causes errors in the machine to the point that I find myself re writing posts more than actually cutting. @cameraman how much editing to your NC gcode do you do before you cut your pieces? Please let me know, I want to collaborate with as many EDM makino owners as I can si we can all benefit from shared knowledge and experience! Feel free to email me ZerocheckEDM at gmail.

    That would be the conductivity sensor for the clean, flush water.
    It has nothing to do with the actual cutting, rather measures the conductivity of the water to keep it within a set limit.
    If it fails, you get either no water sent to the DI resin, or never switch off the DI.
