Printing time VS Cura
-
SO has him nearly at the stage of finally be done with my printer , ive noticed for a long time that print using cura as slicer would take 2-2.5X more time than what cura say . From my observation it seem that the problem is with the infill , it seem to stutter when trying to print it . Printer has no problem getting to speed on perimeter but infill rarely reach the asking print speed . IVe tried different infill type and it doesnt change anything .Him on firmware 3.2.2 i believe. waiting a bit to upgrade to 3.3.
I have done a test a few day ago with a 25mm cube cura was showing 12min i believe fastest i could ever done it was 20min , i tested acceleration and jerk up to 3000 jerk and 7000 acc , started at 1000 jerk and 2500 acc and there was no difference . 10 more min on a small print is not a lot , but when i slice piece and it say 4-5 hour and they take 8-10 hour it a real difference and a problem .
My printer is a custom build core XY with 12mm belt all around , each axis is powered by 2 stepper motor . with a bond tech bmg-x2 as direct extruder

SO any idea how i can achieve actual time or be closer ?

Do you have acceleration and jerk control enabled in Cura? I use that with Cura and I find the time estimates are basically exact.
Alternately you can install the Printer Settings plugin in cura and it gives you a place to enter the actual max speed, jerk, and accel values that you use in your config.g. That may help as well.
I can't spot your travel speed in the settings there. Do you have it set higher than the max speed in config.g would allow?
Are you taking heatup time into account? (that isn't likely the reason for the large disparity in long prints)
-
@phaedrux no i havent try to put the acceleration on cura , i might try it and see when i got some time .
heat up time is not taken in the time count , even at that it less than 10min . when i watch the duet control page every fast travel reach it speed , only on the infill it seem to only achieve like 4-5mm/sec in small area , everything else get to the speed it need to . i went as high as 9500mm/sec for max axis speed on X and Y. ill aad a few more setting on cura and see what it give .

I'm pretty sure this plugin will help.
https://marketplace.ultimaker.com/app/cura/plugins/fieldofview/PrinterSettingsPlugin
Then you can set the actual limits for your printer. The defaults that cura is using are likely intended for an ultimaker printer. So if it's assuming very different jerk and accel profiles the time estimates will be way off.
As I said, my estimates are basically to the minute.

@phaedrux so i gived this a try , nothing the time hasnt change when i simulate on the printer it still double to 2.5x time
Here why it take so much more time the infill layer should all be about the same time but they are not one layer can take 1min and the next one will take 4min when it the exact same things with no change of geometries . any idea what would casue infill layer to have so much different time when they are all the same ?
-
here another test wit ha 40x40x40 80%infill cube , 1.5hour difference with printer simulation , something somewhere is not working like it should
-
@dad003 note the speeds in Cura are in Mm/s and RRF uses mm/min for a lot of things so you'll need to divide the values you put in by 60
-
i think you might ust have found why i keep getting big difference
-
after converting the number it seem to be more accurate now
