No multi-threading in 2D high speed?

[left coast lefty]

Is there a reason there is no multi-threading for 2d high speed? Is there a chance to get it in the future? Just curious.

Do 2D paths take that long to generate??? :headscratch:

Some of them 2d HST paths can take quite a long time to generate. I've asked for multi thread processing on them as well.

I was thinking the same thing until yesterday I saw another programmer here using solid faces for his 2D high speed operations. On his brand new computer it took about 5 mins to calculate. Had he chained a wireframe (lines, arc...) it would have regenerated in seconds.

Thanks for backing me up guys. My home build (i7) has no problem , but the cheap units at work take forever to generate. Can anyone suggest a way to speed this thing up? I just downloaded the latest driver from Nvidia per JP.

 

Thanks.

Good point. Because of the shapes I mainly deal with, solid faces don't work so well for chains. Thanks for educating me.

On my rig, my global presets are "3D App - Default GLobal Settings" in the NVidia COntrol Panel and my monitor(s) are set at their native resolution(s).

On my sysyem properties, I set "Adjust for best performance" everywhwere I could. I run a SOlid State Drive so I do not have a pagefile. Everything runs in RAM. All the eye candy crap is off. Windows Classic view (yeah, boring I know, but function above fashion I always say.

In Mastercam I went with the classic black background, I colorblind anyway, but it takes less horsepower than the gradient. ON the ribon ba tool display, I have that set to no delay. Graphics SUpport is OpenGL only, you may need to play with the three other setings depending on your card. On the toolpaths tab ENable Mult threading is obviously on, I uncheck display surface plane intersections.

 

I think that's it... I'll have to think about it some more to se what else I've tuned up.

Thanks CNC, I'll give these a try.

 

 

[Guest CNC Apps Guy 1]

My pleasure.

 

 

[left coast lefty]

Bump.

 

If you want to bail out or cancel a toolpath generation that is taking too long, or not responding, is there a way out other than shutting down MC?

[MotorCityMinion]

I've been able to hit escape with some luck. Other times it seems like after a certain point in the calculation, it just ignores the escape key.

[left coast lefty]

No luck with Escape. Maybe I'm holding my finger wrong. Can't seem to remember to save it first!

[Müřlıń®]

Press the etc key and hold it down.....most of the time it will get a tic in there unless MC is locked up.

 

I have found X5 is able to drop the thread better than any previous releases.

[Thee Rickster ™]

Murlin, is the etc key beside the any key??

ohh ya i use 2D dynamic to rough cam profiles

some take over 30min to generate

so yes i want multi thread in these toolpaths

Rofl. Stupid auto spell grrrr.

[left coast lefty]

I just sent in a request for multi-threading to QC. Anyone else with this need.....please!

 

Thanks everyone for the input.

[MotorCityMinion]

"I just sent in a request for multi-threading to QC. Anyone else with this need.....please!"

 

Everyone has this need for all tool paths. I think they are aware of it.

 

 

 

 

 

[Tony35]

just sent a request in too

 

cmon peeps we need 2D HST multi-threading!

 

get typing

If your 2d dynamic toolpath is taking a while to crunch, simplify the geometry. A spline with many control points adds a lot of complexity.

 

 

1. use the CAD tools mastercam has to simplify a spline or break it into many arcs.

 

2. the best way is to create a 2d contour with no cutter comp or lead in/lead out. turn on the arc filter at a 2:1 or 3:1 ratio so the toolpath contains mostly arcs. Then backplot the toolpath - save as geometry. Now you have some really nice simply geometry to create your 2d dynamic toolpath with and the calculation time will be significantly less. I've had a 2d dynamic core mill go from 15 minutes down to about 90 seconds by doing this. when you have multiple chains and all of them contain very dense splines the calculation time suffers.
