Yes, still doesn't work.

Have you tried running an an administrative?

I am also having an issue with Mastercam where it never starts at all, when I attempt to open it, it does nothing. I checked event viewer and found this: Faulting application name: Mastercam.exe, version: 26.0.7341.0, time stamp: 0x645da48c Faulting module name: KERNELBASE.dll, version: 10.0.22621.3527, time stamp: 0x83efbeab Exception code: 0xe06d7363 Fault offset: 0x000000000006543c Faulting process id: 0x0x6C6C Faulting application start time: 0x0x1DAA7D2759B8F4C Faulting application path: C:\Program Files\mcam\Mastercam.exe Faulting module path: C:\WINDOWS\System32\KERNELBASE.dll Report Id: c5348f50-e072-44e2-9e17-88b1ce8beeec Faulting package full name: Faulting package-relative application ID: Any suggestions?

Remove the solid history.

I ended up getting everything to work.

Been looking for a method to do this lately as well. Found it today! The menu to choose a Default Simulation Machine for a given Machine Def is under 'General Machine Parameters' in the Machine Definition Manager. Found this thread last week while I was trying a few things out, wanted to update it with an answer. I'm using 2024 U6.

I bought a new PC last year that came with Win11 It's got 6 months on it now and I've had no issues, with Mastercam or any of the other CAD/CAM apps I run We've update 2 engineering PC at work from Win10 to 11 including mine. My work PC has been in Win11 for a couple of months.... no issues A coworker recently had a made to order Win11 and was suffering crashes so bad it was unusual after a bunch of trouble shooting he found the problem. He set his Mastercam installs to "run as an admin" which fixed the problem. As for security and spyware, I have turned a bunch of stuff off and opted out of things. The only way to eliminate it completely is air gap your machine.

This is a new one and glad I keep backups of my workspace file. Anyone else seeing just random issues with Windows 11? I am hearing of large groups down grading to Windows 10 because of how bad the bloatware and spyware is in windows 11 that Microsoft is putting for the the NSA, CIA and other intelligence agencies.

Guilty as charged.

i will focus on those calculations in the beginning . Would you suggest a reliable file or site . Thank you Riverhunter , love you.

Do some testing and find out what works best for you. 15 years ago i relied on excel files with all kinds of crazy formulas. now days its just experience. Below is an example of what i use. the 25% / 50% rule has been fine for me. you can see the pattern in the step over and stock. Ø.750 bem rgh step over .1875 leaving .060 ( just go for it ) Ø.750 bem semi fin step over .046 leaving .030 ( adjust feed rate for stock left behind ) Ø.750 bem fin step over .012 ( really adjust feed rate for stock left behind ) FINISHING BALL ENDMILLS TOOLPATH REL DIA REL LEN CLAMP REC REC ADJ STEP TIP STOCK COOL ADJ ADJ ADJ ADJ TO ADJ ACT SURF TIME PER TYPE TYPE DIA FL C/R LOC RD RL PRO MAT DEPTH SFM CPT RPM % OVER DOC SURF LEAVE HPF STYLE MAN PART# HOLDER RPM FEED ACPTF CPT DIA RPM MAX RPM FEED SFM FINISH SQ IN HP CIPM BEM SURF PARALLEL 0.7500 2 0.375 1 0.73 2.5 2.6 6061 0.100 1500 0.0091 100% 0.016 0.030 SURF 0 3.5 FLOOD DATA FLUTE HSM-BM-M-20750 .750 SOLID 7640 139.0 0.3919 0.0232 0.526 10900 10000 464.4 1950 64 0:00:08 0.0637 0.2229

Thank you so much. So to get a better surface finish (Rt) , a minimum axial cut (ap) and maximum tool radius are required according to the picture below. But when cutting a very smal thikness (ap), this will affect the chip load per teeth required by the tool manufacturer : how to solve this ? So should i start by the finishing operation and adequate tool to know how much stock to leave in semi finishing or roughing operation? I ask for the methodology in general. Again thank you for help.

Thank you for your feed back Could you suggest a guide that helps.

Slykdexia rules KO!

Zip 2 Go is the utlity in Mastercam that share files with all the settings along with post, machine and control definition and if wanted the Machine Simulation file. Simulates correctly on my end. The axis travels and limits are all wrong and need to be fixed other than that without a Z2G cannot tell you why you are seeing the issue you are seeing.

I'm sorry what's a Z2G? I ended up getting the machine simulation to work but not the simulation. Here's the machsim file: VF3ss with TRT100.zip

Why not 2D swept?

I try to always finish anything flat with a flat end mill. when surfacing i always try to use as much on the radius as i can. try searching for some online calculators that will help you figure out step over vs ridge height. when machining hard materials, surface speed varies a lot depending on how much material was left being vs tool engagement. stock left behind will always affect step over distance.

I prefer to teach someone using a file of theirs...so much YouTube content, some is really good, some falls into hack territory...I don't bother with it anymore. There is no straightforward answer... How much stock after roughing? Varies, are there other operations to be perform, stress relieving, cryo, going to another machine for finishing...and more How much stock to leave after after semi? Again, see above but then add material type, allowance for part movement...and more Stepover? Size of tool, style of toolpath used, material, finish requirements...there are scallop calculators out there... flat surfaces general cut paster with flat or bullnose, geometry dependent... and for all of the above....machine abilities...what can it hold? There are more answers to these questions than just X, Y, Z

Hi experts i have some questions regarding 3d surface machining . - how much stock to leave after roughing operation -how much stock to leave after semi finishing operation -the scallop high (step over) in finishing operation: some says that the step over should match the chip load per teeth : https://www.youtube.com/watch?time_continue=253&v=XSiPWq4Osmw&embeds_referring_euri=https%3A%2F%2Fwww.ultrapolishing.com%2F&source_ve_path=MzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMzY4NDIsMjM4NTE&feature=emb_title -when finishig : -is it better to machine the flat surfaces with flat end mill or use a ball nose end mill . -Is it better to finish all surfaces using the same ball nose end mill with the same toolpath if possible , or use separate tool diameters with different strategies. I will appreciate your help

We recently purchased our third AS-200L. and use a older MP post. who did you purchase the post from ? We would like to purchase a good post for this machine. ( our local reseller isn't of much use.

Thanks @JParis There is no option for Canned Text option or a Misc Int/Misc ... on this post. I guess i will have to ask for special of my dealer.

It's rarely the complicated 5 axis toolpath that's going to bite you! It's normally the fact that you fat-fingered subtracting -.020 from the Z origin, and accidentally told it -.2!

Yeah, I have a 32" curved as my main monitor as well. I use my laptop as my second screen, which I have on a cooling pad to bring the level up. I often don't have Mastercam spread full sized across it, as with my seating position, I can only comfortably fit about 60% of it in my view (without turning my head), so I used the side of the monitor for HSM Advisor, excel, etc.
