I'm still running a USB hasp. When I bought V7 it came with a white hasp that plugged into a printer port. I don't remember when I had to swap it out for a USB hasp. I'm thinking X or X2. It still works and CNC still supports it, but should it break or get lost, it will be replaced with a software license.

Yep, you guys are correct on the Machsim/Postability integrated version. There is a reason for the confusion, as confusing as that is! MachSim (by MolduleWorks) has its own post processor (it has to, or else it couldn't figure out how to interpret moves from the CAM system). It's called MultiXPost (https://www.moduleworks.com/software-components/utilities/ppframework/) When you launch "Normal" Machine sim, it's using the MultiXPost to generate moves. As long as it "guesses" the same movements that your Mastercam post will make, you're good to go! If it doesn't guess correctly, though, you can be in for a surprise. An example would be that you're on a B/C machine, and MultiXPost guesses that your toolpath needs B90 C0, but, when you post out of Mastercam, it goes to B-90, C180. Both are valid solutions, but one could cause a problem and one could be fine. What the "add on" allows you to do is to swap out the MW Post Processor for the same MP post processor you'll use in Mastercam to generate the NC, so that the moves that are fed into MachSim are ran through the same engine that will write the code. That means, the X/Y/Z/A/B/C moves are calculated the same as they will be on your machine. You should always see the same B-90 C180 in both (to use my above example). The downside is that it's not simulating M codes, etc. If you have an m-code on your machine that causes the C axis to reset the counter or something, it won't see it. Probing? Won't see it. Tool changes? You guessed it. HPCC causing weird motion? You're not going to see it. You're only seeing what the toolpaths generate. The upside is that because it's not as complete (i.e., requiring a control model to simulate the control state) of a solution, it's a LOT cheaper, and because it's integrated, it's quite fast to check setups and motion. Your Mastercam reseller can give you a final price, but I believe for a "normal" 5 axis machine, it's somewhere in the $3-5k range. What I often tell people about a 5 axis toolpath: Backplot? 50% confidence that it'll run without crashing into something MachSim? 75% confidence MachSim w/ Post Integration: 95% To get to 100% confidence, you really need Vericut/NCSimul/CAMPlete/etc.

straight machine sim? yes all the time Postability Machinesim is much better, One thing Vericut does than Machine Sim can't is Autodiff

I use Machine Sim from Postability on our Okuma 5X HMC's It is linked to the post but I don't believe it runs on actual gcode. It is very useful for instantly checking the stability and smoothness of 5X toolpaths. Of course the final program goes through Vericut before it hits the machine.

Thank for the Replys If it worked for last two yrs on this computer there is no conflict issue It was bought outright at the time so permanant lience stand alone I think some maybe right that its now dead and that will be the end of it as i had it almost from the release of X3 -------Used X19 and stuff on network but not interested upgrading to that system so if i cant get new Hasp will just call it a day -----So many in the UK now using other Cam software and i am begining to understand why
