allocations

[DavidB]

Hi all,

I did a search and found lots of info.

My question is I have 1 gig of ram and when trying to caculate a tool path I get a message Toolpath allocation to low.

Current settings 128000 for both Data base and Toolpath allocation.

From the forum search I found I should be able to easly put data base and toolpath allocation to.

With a gig of RAM, I am running:

 

32000

32000

5000

256000

256000

 

This puts me at 535.5 Mbyte. I have had no issues even with very large (18-22 mbyte) files.

I put these figures in and I still get Toolpath allocation to low.

Recently installed XP service pack 2.

If I try to increase Toolpath allocation anymore I get a Rellocation Error?

Thanks in advance

Hi David

i,ve got my allocations set up the same as yours (must have had the same teacher or installer) .

What graphics card are you using and what have you got your hardware acceleration set at?

I tryed your scollip file the other day and had the same problem as you. Sorry i did,nt get back to you but i could,nt shed any light on your problem anyway.

Hi Dazza,

My graphics card is a NVIDIA Quadro4 900 XGL.

I installed MC on another PC and I could caculate the scallop Toolpath. Its the only thing I could do. My PC is on paper the most powerful PC on site, Go figure?

Thaks for the reply mate.

If you ever get stuck for a powerful comp and car,nt get on at work you are more than welcome to shoot around the corner and chuck it on one of ours. We have a couple sitting here that are a waste for what they are used for.

Have a good day

David I have gone the other route soemtimes and had good results. Set your Database to 100,000 and your toolpaths to 1000 and for soem strange reason this will work better than the other way seems weird but it has worked better on big files than the other.

Interesting... I am still running the same configuration and have had zero trouble even with some very large tool paths (multi-days runtimes).

David,

 

For the 3rd line (numbers for undelete)

If you have big solid inside Mastercam ,sometimes

lowing the toolpath allocations will help instead of enlarging it .

Parasolid kernel use other way of using memory ,enlarging your allocations leave it without memory and that`s may be the case

David,

I have experienced low toolpath allocation recently with pocket rough toolpath. I ran TPCFG chook and unchecked "Constant Z ops:use FastZcut Technology."

This let me program without a hitch.

Here is an excerpt from the help in that Chook:

FZT is enabled by default. However, it may be more efficient to disable FZT in the following situations:

 

¨ When a typical part size is small relative to the cut tolerance and Z stepdown

 

¨ When you run multiple sessions of Mastercam

 

¨ When you need to set the toolpath memory allocation less than 50MB

 

To disable FZT, deselect the checkbox on the Toolpath configuration chook dialog box.

Memory allocation requirement

FZT requires a significant amount of memory. FZT uses the toolpath memory allocation set in the System Configuration dialog box. (Choose Main Menu, Screen, Configure, Allocations). The toolpath allocation must be at least 50,000KB (50MB), but you may wish to increase it. The upper limit is ½ of the computer’s physical memory.

 

For example, if you have 256MB of physical memory, set the toolpath allocation to 125,000KB (125MB).

 

Maybe this will help.

After programming the trouble toolpath, I go back and enable FZT.
