Layer time, hight and look ahead

It would simplify a lot if the Z height and time for the specific layer were specified in preview mode.
Also a look ahead function for maybe next 20 layers in FFF-settings. The funktion should be to gradually accelerate or slow down the layer time so that the difference does not become too large.
It would reduce shrinkage effects that occur between layers with large differences in speed. Especially ABS.

Re: Layer time, hight and look ahead

The cooling feature does this to an extent. It will change the layer speed for layers that would otherwise print faster than 15 seconds, and slows them down to up to 20% speed to get them to be at least 15 seconds. You can adjust these numbers to fit your models better. For instance, if you're printing a gigantic part, then the cooling overrides at their default values won't have much effect since no layer will print faster then 15 seconds, but you can adjust this value for your part if needed.

Re: Layer time, hight and look ahead

Yes, it is good but only for small parts. My part would take days to finnish.
For exampel:
In my latest build, the first 15 layers took an average time of 6 minutes / layer. And the layers after that an average time of 1 minute and 6 seconds.
And this build takes 16 hours.
Now what would be nice is if the the first of the fastet layer could be set 0,8 x the last layer time until it reaches 1 minute 6 seconds whitin marginal.
4,8 ; 3,84 ; 3,07 ; 2,45 ; 1,96 ......
And then the other way around if comes to greater build time higher up.
I think the effect you can see in the picture would be less.

Re: Layer time, hight and look ahead

Did run some test but it didn´t give me the result I was hoping for.
