Problems with dual core computers?

[Trapper Paul]

Is anyone using the new dell dual core computers?

Mine is the Precision 390. I'm having a few issues with version 9. When I hit level it locks up mastercam. Even the boys at mastercam are stumped.

Are you running xp64 bit or 32 bit?

[Matthew Hajicek - Singularity]

As far as I know 9 won't recognize a hasp in 64 bit, so he must be on 32 bit. I put together a dual core AMD at home, and I've found it to be a bit buggy. Downloading CPU drivers helped a lot. If it's a Dell packaged computer though it should have all that covered. You could try setting the affinity of the Mastercam.EXE process to one core or the other. That's helped me get some programs running more smoothly.

Today I just got my new workstation: a Dell Precision 490+Quadro FX550+XP PRO 32bits and I experienced randoms crashes with MC V9.1 MR304 (stuck here forever...). Mill.exe crashed at least once per hour today. I'm gonna look into Video driver. Do Nvidia 91.36 Quadro drivers should be OK? Which Profile must be selected? I just read on the forum that Unified Back/Depth Buffer must be unselect with MCX...I will check this setting with MC9.

I'll look at my settings and get back to you.

It was hard getting it to run ok.

The 'Unified Back/Depth Buffer' setting on some Nvidia cards can sometimes causes graphic issues when backplotting MCX toolpath.

 

FYI (from X-MR2 on...),

Settings - Configuration - Screen (page) - 'Disable Front Buffer' option checked ON will tell Mastercam to do its own thing to deal with the 'Unified Back/Depth Buffer'.

Meaning: You can tell Mastercam do deal with it, without having to disable that setting in the graphics card driver.

Hi!

I've used my Dell precision 490 for almost 3 months now... and nothing has changed I still have random crashes very often (once per hour or even more)

 

I deactivated Autosave, Depth buffer, updated Nvidia drivers 91.36,... I even try to deactivate video acceleration in windows control panel(cursor to the left) and still have crashes. So i'm starting to wonder if it's a video issue.

 

Any help or ideas ?

Hi Matt,

 

I've just got a new computer with the Opteron dual core processor,

 

How do you assign affinity of mastercam.exe to a certain core ??

[Ken Chase CNC Software]

Have you tried disabling OpenGL hardware acceleration in Mastercam itself (ie. Settings->Configuration Screen 'Disable hardware acceleration')? You'll have to exit Mastercam and restart after changing this setting in order for it to take effect.

[Matthew Hajicek - Singularity]

To assign affinity: Start your Task Manager (r-click on task bar or ctrl-alt-del) and go to the processes tab. Find the mastercam.exe process and right-click on it. If you're on a multi-core system, you'll have an option for setting affinity. Click on 0 or 1 (or 2 or 3 if you have a quad core) and the program should run only on that one core. This is only for the current instance, so you'd have to do it every time you start Mastercam. There are some free downloadable utilities that claim to set the affinity of a program / process for every time it's run, but I tried one and it didn't work for me. YMMV.
