Backplot speed

[Dontlietomeman]

I have adjusted the slide bar but no matter where it placed backplot runs the same slow speed. What ama I doing wrong.

Verify work fast!

Large toolpaths can make it stutter, if you have many surfacing paths.

 

To the right of the speed slider adjustment is the toolpath slider. You can drag the slider through the toolpath, it that helps.

I've noticed that if I have no arc moves and a TON of tiny segment linear moves, that my backplot will go slow,but then again, I don't have the most powerful computer here at work.

I still have a Pentium D 2.8ghz, but for most of the stuff I do it works fine.

[Mr. Wizzard]

Sometimes it helps to click on the "restrict drawing" button while backplotting a monster toolpath. As the screen fills up with your tool moves, it drags down the screen performance. If you click the button, it erases all toolpath moves up to the current position from the screen. That will help speed up the remaining moves. You can do it as often as you need to as you're backplotting to clean up the screen and help speed up the motion.

Go into the Verify Settings and adjust the Tool Tolerance. The tighter that is the slower it runs. I usually run at around .002 for quick checks, then occasionally crank it to .0002 for surface tolerance checking.

Oops, didn't realize you meant Backplot, not Verify...

Are you saying you can't adjust the speed at all? Or it just seems slow to you?

How many toolpaths are you backplotting, What kind of toolpaths are they? How big are they?

[MotorCityMinion]

I get slow speeds with back plot as well when doing just a single tool path. A simple, single 2d contour, and it crawls. Back plot several operations and it gets faster. Back plot a huge surfacing tool path and it's very fast as well. It' seems strange because I can verify that same single tool path and it runs so fast you can't see it unless you slow it down.

[Mr. Wizzard]

I think the speed slider bar is relative to the size of the toolpath being backplotted. Leaving the slider bar in the same spot will create a slower speed on a smaller toolpath (when you just hit the play button) and a faster speed on a larger toolpath or toolpaths. Why, i don't know, but that's what it seems like.

Yes I remember when that changed from "time based" to "op size-based" back in maybe X or X2. Still miss the old way; sometimes you just cannot make simple toolpaths backplot fast enough (esp. in Lathe)

So, being very frustrated today(cuz that's the kinda day I'm having.....my turn...) I decided to find a nother way to speed up the backplot on simple contours etc.

Go to your backplot options page and set your endpoints down to 2. On the vcr buttons , left click forward step button(not play) and hold it down. You can adjust that number to suit your needs. I know it's labor intensive to hold the button down but it will give you a faster controllable backplot. Not ideal, but it's something....
