Mastercam 100% CPU Load

[jimspac]

Hi Friends,

 

I was trying to do some work building an EDM electrode with surfaces when I noticed a lack of response while creating fillet radii. I checked in Task Manager and was showing 100% CPU load. I closed down Mastercam and checked task man again and load dropped to 2 %. I opened Mastercam with no open file and found 100% cpu load again. I did the same checks with cadkey 19 and Surfcam 2002 and found no load. My IT manager found the same results on the other 2 computers we are Net Hasped to. Our machines are all Dell Optiplex or Dimension P4 2.5 ghz, 256mg ram, 64mg Intel integrated graphics adapter running Mastercam 9.1 SP2 with Nov 2003 maintenance upgrade. Anyone else having such problems, or is it a "Dell" thing?

 

Thanks

Do a word search of this forum. Your question has been covered many times.

Do a surch on this board.

We have had many posts about this issue.

That is great news Ken, thanks!!!!!!

Thanks Ken. My IT manager heard back from Ruth D from CNC Software today stating that the 100% CPU load is normal and does not affect performance. She further states it has been normal for the 8 years she has been using Mastercam. The IT manager and I are still at differences regarding system config. He showed me specs from mastercam.com showing a Pentium with 32meg was fine. We are using 9.1 SP2 Mill Level 3, Lathe, wire, and Solids. I feel we need 512meg ram and non integrated graphics as we work with parasolids and UG models.

 

I am glad to hear that it will be taken care of for ver X.

 

Thanks all

You do!!!

I'm surprised you system will run solids at all

with an onboard video card

I use a laptop from the battery and when i run mastercam it drains the battery really fast.

Yes! Your right.

Because the CPU is reporting 100% useage, the fans come on as soon as you start Mastercam

and stay on as long as its open.

My laptop runs MC OK, but the fan gets irritating after a while.

I have a friend who's laptop decides its overheating after 5 minutes of MC and shuts itself off

None of the power managment setting wil prevent it

Here's my findings:

 

MOBO ambient temp: 25 C = constant

CPU temp before launching MC: 35 C

CPU Fan Speed : 3515 rpm

 

After launching MC I kept it idle for about 10min to reach steady state conditions,

 

Mobo ambient temp: 25 C = previous value

CPU temp: 47 C

CPU Fan Speed: 3688 rpm

 

Thanks God this issue addressed in version 10.

ASUS A7V333

Oh yeah and MC 9.1 SP2

Here's a trick you can use in the mean time. If you walk away from you Mastercam, or leave it idle while you do something else, open any dialog box. Open the Ops Mgr and the CPU goes to 0. Obviously your not going to "wear out" the CPU. But Heat is the enemy. It's especially important if you have 3 PC's in a small office in the middle of summer. Damm things can be like space heaters.
