This is the way it was explained to me at one point in time and it made sense to me. If you made a program that ran perfectly 2 years ago and in-between that point in time and now you've made minor changes to the machine/control definition. Now that customer comes back and asks you for the same parts. If you can just open the file and post the code and run it knowing it worked good the last time thats great your ahead of the game. Otherwise you would have to track ever single change you made and then go and change the mmd/control definition to match what you had back 2 years ago. Any new file should use the new machine/control definition. You only need to replace the machine def on files you've previously programmed where you want those changes applied. Its a good system but I understand your frustration too. At least it looks like there is a way to do what you want within the System configuration. I dont think that was in the configuration a few years ago or several years ago when I got the explanation.

If you are chaining an arc and the post is llnearizing the arcs you can try turning on the arc filter tolerance. On in the control definition the Support arcs in XY, XZ and YZ might be unchcked. Without a file though its tough to say what the issue is.

The complaint wasnt valuable. Trust me it had zero value and didnt describe any issues.

@byte yeah I saw that after I typed my reply here. He complained in another thread (I've hidden the complaint because it had nothing to do with the topic). If you are going to complain in a thread at least describe the issue you are having.

If they did this it would drive the price up astronomically. I think the option to purchase your own verification software is more ideal. If you want it you go and get it. If you don't want it or need it then you are good.

Did that feel good? Since you wont elaborate on the issues you were having we cant help you. Read my posting above there are people here with a ton of experience willing to help. If you cant give example or post files demonstrating your issues then why even complain. If you've gone back to X9 my guess is you didn't like the interface which is understandable because it is different. Let me ask you how long did you try to use the software before going back to X9? A couple of hours?

It looks like it might be related to a Windows Media pack. Cause Mastercam Simulator requires files from the Windows media pack to be present. Within Windows N and Windows KN versions, this package is part of an optional install causing Mastercam and/or the Simulator to not launch. Solution Install the Media Feature Pack provided by Microsoft. Windows 10 (Install the version matching your OS version) https://support.microsoft.com/en-us/help/3145500/media-feature-pack-list-for-windows-n-editions

You can also convert to PMesh and then save the PMesh to a level. There is one major benefits to this is that you can then delete the stock model. Then reference the PMesh vs the stock model. So if you go into an operation linked to the stock model and change something simple like the stock to leave on walls then you only need to update the operation and you dont have to wait for the stock model to regen too. Of course if you changed your stock to leave on walls by a large amount then you might want to re-create the stock model but most of the time its a small amount that doesnt really visually effect the stock model.

If I had a dollar for every-time I heard "Looks good in backplot and verify". Using the software especially the 5AX toolpath is more than just throwing a toolpath on a part. Getting a 3rd part verification software would be ideal as it would show your issues before you even got to the machine. Some companies think this is expensive but you crash your machine it would be cheap. @BILL HUNTER you can see there are several people here willing to help but you gotta give in order to get. Complaining about something and bashing Mastercam isnt going to get you anywhere on here. We understand you cant share your specific part can you make up a part that is similar and demonstrates your issues? If you do I'll bet you, you would get at least 3 different suggestions on ways to program your part and probably a bunch of different ideas to try at the machine. What machine are you running? Some machines run different based on bit settings on the control. If its a common machine I can check out post library for bit settings to see which ones influence the machine (yes we put that in our posts for common machines). In our posts we can flip a switch and change the TCP coordinates between table and workpiece. The output is very different. If the post is setup for Table coordinates but the bit setting on the machine is setup for workpiece this can result in bad things. There is probably about 50 switches in our posts so it's possible a combination between bit settings at the machine and settings in the post are not setup 100% properly. The post team at In-House contain some of the smartest people I've ever worked with and I'm sure that applies to other resellers and vendors who sell posts as well. Working with the post developer might be a good starting point. I know we've signed NDA's to work with customers and am sure your reseller could do the same thing. I'm sure you could even have the post developer sign an NDA too.

Do you have stock to leave set? In the Area Roughing & Hybrid toolpath you would find this on the Model Geometry page.

I think you may need your reseller to assist you with this. Obviously there is something going on with that PC you are trying to install the software on.

The version you have installed is newer so I would keep that. Chances are if you uninstall it windows will update it anyways. If Mastercam doesn't install you can try uninstalling it and then installing the 2017 version 14.15.26706

Strange.... Have you tried installing the Microsoft Visual C++ Redistributes. I think they are on the full download. They should be under the SetupPrerequisites and should be in the folders called VC2012, VC2013 & VC2017. Here is a neat link to all the Visual C++ files https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/ There are times when we've have to re-install these or the install doesn't work.

Did you figure this out? Can you navigate to the folder location in the second screen shot?

I've used it. Usually the new geometry gets saved to a level that you can specify. I think level 255 is the default level.

See image below. Should be available within Mastercam when you select your machine to Run Machsim.

It sounds like you got a network software license. They just introduced the option to borrow a license from the network software license. Essentially you check the license out on a PC or laptop then you can pick that computer up and take it home with you. You can check the license out for up to 10 days at a time currently. Once you are done with it you check it back in. If you did get a single or local software license you can deactivate it and activate it at home this step is a bit more work and confusing the first couple of times you do it but you can do it. Once you check out or borrow the license you are no longer required to be plugged into the server. So this would be just as reliable as a HASP. I understand having a physical hasp makes it easy to share or take home but once you use the license borrowing tool its almost easier because you don't have to worry about forgetting the Hasp at home. You would just have to worry about forgetting the computer or laptop at home but thats not likely. They do this still its called the Mastercam HLE (Home Learning Edition). Its free on Mastercam.com When saving a file it will save it as EMCAM file which industrial seats will not be able to open this is to prevent posting. You have some good points in your discussion and you caught the attention of Pete Rimkus from CNC Software as he posted in here. As Gcode said I would reach out to sales _at_mastercam.com and see if something can be done. its worth a try in the very least. Good Luck

@TERRYH you can download it from Mastercam.com but you need a login.

Since its a custom post I'm assuming the post is in the machsim folder? Did you check the box to "use external post" before simulating? if the post isnt in the folder that option will not be available and is probably why its not showing you an accurate simulation.

Integrated GPU or out of date graphics drivers. If you have a good graphics card you should be able to force the PC/GPU to be setup when you are using the software to use the graphics card. Good cards will also allow you modify a few settings that can make a difference in performance of the software too.

@Tim Johnson We've setup a couple of these posts in the past and its been a while so I may not be correct but I believe the posts were setup with 2 machine defs a mill one and a lathe one. You would do most of your programming within Mill and then then when you need to use this option you would load a lathe machine def in and program your toolpath within Lathe. I also believe this is an option and you may have to order at the time of purchasing the machine. But you might be able to get it added on after the fact. You would have to check with Okuma. Mazak has something similar called Mazak Orbiturn but I'm not sure how that cycle works and am pretty sure again this is an option on the Machine.

We've set this up in a few of our posts as a Misc. Value. It is not supported by Mastercam yet. You will probably have to do it as a manual entry in MT for the time being. Works really well though and its very impressive to see it in action.

I believe the video below shows the Turn-Cut feature Okuma has. Its similar to a d'andrea head. @CHeimbach maybe reach out to the company that provided the post and ask them for a sample part file so you can see how it should be programmed. Everyone above has pointed you in the right direction in terms of setting up your planes properly.

Depending on the version of Mastercam you are using I'm pretty sure there are issues with this chook. Its been a while since I've used it as well but I don't think it worked in Mastercam2020. I remember the training/book department said there were issues with it. I have not tried it in Mastercam2021 yet so I cant say if it works in that version.

What does the part look like? What toolpath were you using? With the Multi-Axis toolpaths you can usually cut the same part using 2 or 3 different toolpaths. There is a lot of knowledge on this form usually providing a bit more information will get people to jump in and help you.
