Roger, Thanks for the input and checking into this post for me. I realize that this is an unusual (old) control and that the post was going to be an issue. If you do find it, that would be great. My employer understands that we might have to pay for this particular post or upgrade our control which obviously would be much more expensive than the post. Please email me at [email protected] either way. Thanks, Scott Garrison Weiler Engineering Elgin, IL

Watcher, Thanks for the tip. I will definetely keep that in mind. I do have a 6MB post that I'm using now and works great. I'm thinking of just modifying that post. All I need is to change it to use spindle codes and then the vectors. I think it is better than trying to work on the 3000c post they gave me which isn't even close. It also is for a 4th axis which we will never run on this machine. My 6MB post is just a modified Generic Fanuc post. Thanks for the info, Scott

To all, That's interesting, I did not realize that part of the post is compiled. I've never seen this .psb file. How is it created? Is there a compiler? I really don't care to hide anything on my posts anyway so it's not really relevant. My post output will be unrecognizeable to most programmers anyway G45 H01 Z-0 length offset anyone? I hear what everyone is saying and I appreciate the feedback. I don't want to be considered a troll, although I don't always have this kind of free time to post. I'm slow right now & that is why I'm trying to get this post figured out. I've been putting this off since X came out so you can see that I don't get this slow often. I have been at this site before but just to browse, I have been using MC for a couple of years now but only for limited jobs like punch nests for our deflasher tooling. Everything else is simple 2-1/2D. I do on Genesis whick rocks for hole making (90% of all machining). I will contribute to this site when I have something to add, right now I'm just getting my feet wet. This post is why I haven't done more, we need to be able to run all jobs on all machines. I have 6MB & Haas post working fine but not this old 3000C. I just got our Agie wire figured out and next to come is our Mori lathes. I want all my posts figured out before I get deep into the software. I already have the Mastercam post reference guides, infact, I actually printed all of them out and put them in binders (last time I was slow) I work better from manuals, can't explain why, guess I'm too old school. I will first see what my reseller has to say and if I get nowhere, I will see what I can do with some help fron CNC. I do have to say that the post structure for MC is a little tough for me to read, I have to unlearn some things engrained in me like # sign for comment, in SmartCam that was for variables. I had a devil of a time figuring out the formatting statements! I'll let you all know when I have a 3000C post working. Roger, thanks for the tip, hope I can return the favor someday. Also, I work with a guy who posts here under the name of chipman who's been here a a while longer tha myself. He programs our molds & I do the machine parts. Scott

Ron, Thanks, I'll check that out. I have already searched this board for Fanuc 3000c & G39. I only came up with 2 matches that were not useful. We've spent thousands on multiple seats at my company so it will not be a big deal to pay for a custom post. You know, Gibbs does not let end users modify posts. You need a compiler to do it and the only way to get one is to take the class at their corporate office in California. This way they control the posts much more carefully and therefore their resellers get their cut. I worked for a Gibbs reseller and when I did a change for a customer I sent it off to Gibbs with all the machine/control info where they gave it a long & descriptive name and tossed it into their library. If someone in the future needed a post like that they would charge for it. They would charge for ther same post over & over. They also guarantee the code because they do have that control. If Mastercam had gone that route we would not be having this discussion. I don't see that much difference between coming here for technical support, versus calling the reseller for said support, which has to be paid for. How many people on this site come here 1st to get an answer instead of calling the reseller 1st or even pay for technical support? How different is that from sharing posts? Now it's different if people are hoarding posts to accumulate a huge library that they can market them to MC users. As far as I can see there are no copyrights on these posts like other intellectual property. It just seems kind of willy nilly how these posts are handled. If being paid for them is so critical they should have made them end user non-modifiable. Well, that's my 2 cents. Scott

Yes, I did read read the FAQ. I more or less am just trying to see if this is possible or if it is something to do with misc. variables. & if anyone has seen this before (even with non-Mastercam software). I've written/modified plenty of posts, mostly for SmartCam & Gibbs and I'm just getting into the MasterCam Posts. I've already made changes for our 6MB and Haas's. I have emailed my reseller with all of the above and am waiting for a reply. Correct me if I'm wrong but I believe that this is not an easy change, even for someone experienced with MC posts. That's the only reason I asked if someone already had one. If I can't get Mastercam to do this we probably will just upgrade the control to a newer Fanuc. Those are the two routes we have. Oh, just to let you know I'm using a 30 year old text based cam system called Genesis that can do these vectors. I'm not dead in the water here. We've been making money this way for years.

Del, Is that how you got to be a Senior member with such helpful replies as above? Also, that Matsuura will be running when our new Haas's are in the boneyard. Scott

We've got this ancient Fanuc 3000C (circa 1979) on a Matsuura VMC (solid as a rock). I'm looking into getting the post ironed out. This control has no look-ahead capability, therefore it needs some extras that are not required nowadays. They call them vectors and what they are is a way of telling the control what direction the first move is after a cutter comp lead-in move. It uses I & J's ex: G90 G00 X-.1 Y-.1 G01 G41 D01 X0. I0. J1. Y1. would tell the machine the first move is 90 deg. the I & J values are unimportant, it is the angle (arctan) they describe that is. These are based on a circle with a 1" radius. i.e. for a 45 deg. angle = I.7071 J.7071 for a 135 deg. angle = I-.7071 J.7071 for a 225 deg. angle = I-.7071 J-.7071 etc... Also, Whenever there is a corner move with no radius programmed i.e. G01 X1. Y3. X5. ETC... there needs to be a G39 (corner offset code) as well as a vector showing where the next endpoint is so the machine knows when to start decelerating, ex: G90 G00 X-.1 Y-.1 G01 G41 D01 X0. I0. J1. <--- C.C. VECTOR G39 I0. J2.1 <---------INCREMETAL DIST. IN Y Y2. G39 I5. J0 <-----------INCREMETAL DIST. IN X X5. It also uses spindle speed codes from a table but the post I have has this and just needs to be modified. Does anyone have a post that does this? The post I got from my reseller for a 3000C doesn't do this. Is there something else needed as far as misc. values or such? I more or less just need to know if this has been done before. Also, if someone has a working one and wouldn't mind sending it to me it would be appreciated. Thanks, Scott Garrison Weiler Engineering
