    There are things you can do on the settings side of Creo/ProE to make these problems go away with almost 100% certainty. I don't have the instructions off hand, but it's in the history on here. Been floating around for over a decade.

    post err.

    Can you give us anything more as to what you were editing, or did this just come out of nowhere? We can gladly help, but can't help if we don't know what is going on. You will need to look at the structure of the string select table in question and see why it might be erroring out. If you added to it you just need to readdress the table length.

    Backplot would have to be kinematically aware in order to give you accurate kinematic angular output. So as 5th axis has stated, machine sim would be the place to make that happen for now. For truly accurate values you would want a post linked machsim.

    mind blown

    Has there been any documentation/explanation of these changes yet to showoff the new features?

    Odd threadmill action in 2018

    This is one of those moments when the best enhancement would likely best be a warning that tells you that you have just changed following parameters as a result of clicking the tool, or make it a setting that we can change based on preference. But certainly a no win situation as we all have different schools of thought on the subject.

    HELP WITH G05.1

    That's one of the first things I check on a new machine. Also, default to G49 when reset is pressed. That one will make you scratch you head for a minute until you realize that's why the machine keeps alarming out. Stock MPMASTER i was last playing with didn't have a G49 in the header. FWIW, all modal codes possibly used should be in your header of any posted code.....

    HELP WITH G05.1

    I just ran into this bug the other day. Can't start up G5.1 at a null Tool change. By default this happens if you use a drill cycle followed by anything else with the same tool.... I didn't learn the hard way so to speak, but did scrap a really cheap part. It's and easy fix, and I did it, but it made up mind the other day that I am going to be moving away from the MPMASTER. I keep running into issues, and it is a difficult post to make edits to given its shortcomings from a structure perspective. I know it's been the gold standard for many years, but after reading through one of the recent releases of the MPFAN post from CNC I will be adding my needed functionality to it as it is a far easier post to follow and make "simple" edits to. I know they are based on the same post but it seems the recent maintenance to the MPFAN post has been very good, clean, effective and mostly up to date with current practices. I just feel the MPMASTER needs a serious revamping to condense functions and whatnot. The G49 issue with G5.1 wouldn't be an issue if there were a few safeties put in place to keep track of length comp, something I have done for years in my 5axis posts as wcs changes require dropping G43.4. Once you start keeping track of that status you can put error handling to make sure comp is on at the end of you toolchange and null toolchange sections. But moreover you should only really have two places in your post here length comp is turned on and you can only turn it off in a routine that will eventually lead to it getting turned back on.

    5 Axis Motion Between Planes

    Video as promised. Not the most optimized program, but plenty fast enough for the operation as it still beats the second op machine by a few seconds.

    5 Axis Motion Between Planes

    It's as good as the post and simulation engine are. The main difference is that it isn't reading your posted G-code, but rather a separate intermediate simulation code file, which if done right will move the simulation machine whenever and however the post would output a g-code move. I can't stress enough that this is not a G-Code simulation. But it is pretty good for checking clearances, angle output, and kinematic motion.

    5 Axis Motion Between Planes

    I just wrote a 4 axis program for some parts at the old workplace. I'll hopefully prove it out this afternoon. I'll post a vid. Basically you save out to a level the end point and start point of the next path. Create a spline or line arc path between the two points, then add tool vectors at the start and end points, and any intermediate vectors you need along the path to force the kinematics you want during the transition. Set a high feed rate, turn off any linking moves and voila, you have linked from one path to the next using curve 5x.

    5 Axis Motion Between Planes

    I know I'll get lambasted for say this, but I don't agree. I personally won't rely on any level of simulation to tell me if a program is good or bad before it hits the machine. The only thing I will rely upon is proven processes that work for me. Many business owners won't cough up the dough for simulation software. As such there are many other ways to make sure you safely execute programs on the machine tool without a crash or unintended consequence. It just takes planning and understanding of the situation. Is it the most efficient way to get it done, no. But is it worth bothering to do without simulation? Most definitely, and is 100% situation based. Knowing the intent, combined with knowing the machine, and having eyeballs on code before you put it to the machine are key. But in the 3+2 world, as long as you have a good proven post, and know how to verify clearances, the only thing that makes running tool plane work without simulation riskier than on a 3 axis VMC is the cost of the machine.

    5 Axis Motion Between Planes

    I agree with Ron. It all depends. But in general, yes it will be faster. But is it worth the time to program it and debug it? Likely not. Unless you have cycle times under 5 minutes, you likely won't see much benefit from it. Where it saves, once again as Ron stated is in the retract and approach moves. If you combine those with rotary motion, you will essentially be eliminating those retract and approach moves, so depending on the machine you might save up to 2-3 seconds per rotary axis repositioning, sometimes more, sometimes less. But I don't see it as a big deal unless you are looking for those few seconds on a long run short cycle repeat run job. Multi-axis link works ok in select cases, but I have found that you end up using Curve 5x in order to get the smoothness and control of motion you need for the shortest amount of axis movement. This is also a good opportunity for cycle time improvement on horizontals and verticals with a 4th axis. Tool changes in certain kinematic arrangements can also use these techniques to get in and out of the part faster and with control.

    quantity of programmers required rule of thumb?

    I'd come help to give you a "vacation".

    Chamfer mill in a C Axis lathe and wrap a Radius.

    You could mange that with a back chamfer tool and undercut it couldn't you?
