Intent Profiles

[walterwoj 0]

I have upgraded the last 2 versions of cura and looked for the new intent profiles but they are not there. Just my old profiles.  I even told cura to remove my old data on the last version but it's still no there.  Is there somewhere I can download them to try them out?

Intent profiles are currently only available for the S5 and S3.

Apparently I missed that detail in all the notices... any idea when it will be available to everyone?

The intent profiles are really just a way to group profiles.  It isn't much of a feature.

 

The bigger deal is that when the UM3 came out (and then S5 and then S3) the profiles concentrated more on speed and beauty instead of accuracy.  There is a new profile for the S5/S3 that concentrates more on accuracy than speed.  If you have a UM2 you don't need this as the profile for UM2 was accurate already.  If you have a UM3 then let me know and I'll tell you what settings to change to sacrifice beauty at the gain of accuracy (for mechanical things that need to fit perfectly).

I’m battling with accuracy of my UM3e - so if you could let me know I would be very happy.

 

thanks

Some of the critical things below: line width matching nozzle width helps.  slow speeds (40mm/sec) helps a lot.  turning off jerk and accel control (or setting to highest reasonable values) helps a lot because it doesn't slow down as much on the corners causing blobby corners.  "outer before inner" makes it so the inner wall isn't pushing out on the outer wall which helps also.

 

dimensional accuracy profile - engineering settings  - accuracy mode
Line width: 0.4
Wall thickness: 1.2
Top/Bottom thickness: 1.2
Speeds: 35-40 (all speeds, except travel)
Jerks: 20
Horizontal expansion: -0.03
walls: 3
Inital Layer Height = 0.1
Slicing Tolerance = Exclusive
Combing Mode = off
Outer before Inner Walls = Checked

Thanks @gr5 -- this is really helpful! That said, it's been more than a year -- do you know if there is an intention to support the UM3 with "intent profiles" in the future, or at least an "engineering mode"? Or is the UM3 just too old of a printer to be supported any longer?
