there is def something corrupt after the move to 4.4, i cannot delete some of my custom material profiles, the 'remove' option is greyed out !, (these are not the active profile as i know that will be greyed out)
anyway to remove old material profiles other than through the UI ?

As I said in am not sure this magic layer works in theory, as you can't guarantee what step count the print starts at. You could start the print on the half step and then it makes no odds if you use these 'magic'numbers at all, in fact in that case you would be better not to use them......
I am guessing this is why UM don't use the 'magic' numbers and people don't see any improvement from using them ?

I believe so, yes. I use them mostly with 0.2mm to 0.3mm layers (for speed). I find if you go thinner than around 0.06mm the visual quality starts to get worse again.
The "Z magic number" for all UM printers is 0.04mm which means you get more integral number of Z steps if you print with 0.16 layer height than 0.15 so I recommend 0.16 over 0.15 layer height but it really doesn't seem to matter much and I always forget and have often used 0.15. But more likely 0.2 or 0.3 (0.32 would be smarter).
Does focus magic number really make any difference when you cannot guarantee the first layer is on a full step. What happens if the auto bed level for example starts on a half step and then using 0.04 would just result in going to the next half step? (Or have I miss understood)

I guess it hardly depends on your needs and workflow. I am with you, that profiles, when they are working as expected, are easier and more straight forward, but project files are a good work around for the problems after Cura updates. Not always, I heard about problems with the 4.4. update and loading older project files, but personally I have no problem at all with it.
I never had the need to create custom material profiles. I print 90% of my materials with the default generic settings and I am fine. If needed I adjust the temperature and that's it. In previous versions (firmware & Cura) it was not so easy to create a working custom profile that is accepted by the printer, so I gave up to create them. But in the meantime it is working fine and custom materials are also synced to the printer. (S3/S5, UM3? - not sure) But I still don't need them and keep it as simple as possible.
Regarding quality profiles, I usually have only one profile and adjust only the layer height if needed. I gave up using a "draft" profile to print faster, because I mostly print technical parts and need dimensional accuracy, so a draft which doesn't fit is not a useful draft for me.
The good thing about Cura is that there are many ways to reach your goal and you are not forced into a certain workflow.
Thanks, appreciate your advice

It is not so comfortable as when working with profiles, but it is safer in my opinion.
I have no custom material profiles, I use only the generic profiles for all (or most) materials and adjust just the temperature if it is needed. My other settings, quality, whatever, are saved with the material temperate in the project file.
When I want to print another object, but with the same settings and material, I just load the previous project, remove the object, load the new one and print.
Thanks, yes that's the part I was missing (remove the model and reload a new one)

Ah ok, that makes sense. In reality I guess I could easily use the default material profiles and tweak like you do, however i would prefer to keep being able to use different print profiles as then its easier to switch between them. Unfortunately as you have found UM development have a bad habit of messing this part up and quite often upgrading the Cura version spams custom profiles and sometimes, most annoyingly, it just messes up a few settings rather than them all !!!!!, so its really hard to detect until you see something odd in the print !!!
-
How do you use project files over material profiles ?, can you explain?
I have various slicing profiles and material profiles, how do project files replace the combination of slicing with for example PETG and two different quality settings ?
-
Thanks for checking but the issue occurs when you create a new material profile in 4.3, then upgrade to 4.4 and somethings get broken.
Bit of a nightmare as it's happened before when upgrading.
-
No, you are still using a material profile from ultimaker (black CPE in the screen shot), I get the problem when I use my own material profile for a different PETG. Its fine when I use the UM CPE just like you have.
-
PLA associations are ok, CPE are broken..., i can still see my custom profiles are there are now zero default profiles for CPE with me materials.... not great
-
there seems to be that something has broken with the material associations in this version, my cpe profiles are based on the default CPE profiles, but now the association is broken, this happened with the move to 4.3, very annoying as to get the association back i have to delete my profiles and reduplicate from default CPE and start again.
-
no, it has somehow got confused and cuased them all the be greyed out, i cannot even see any of the default profiles, all the UM defaults have gone too for any nozzle size ! 😞
-
4.4 has now lost the ablity to pick profiles from the drop down !, you cant see or pick them
-
Interested to know what has changed in these profiles over the normally supplied profiles. For example what makes the 'visual' 0.15 layer height better than the previously default 0.15 layer height default profile.
I have created all my own profiles for accuracy and visual quality (I don't care about speed), so I am interested to see if these new profiles can improve on mine and more what they have tweaked to get improved quality for example.

The only thing a S5 does "on its own" with the power switch off is lowering the bed; actually gravity does that. The induced current by the z-motor could result in some flickering. For sure it does nothing else as that power switch is a mechanical switch. If it still has power, then something would be wrong with the switch.
The only other, very unlikely, explanation is that it is haunted by a 👻 😉
Haha, yes, I updated the first post to say it was a false alarm !!, turns out when the person in question said 'printer' they meant inkjet not 3d printer!!!!! 😄😄😄😄
-
Hi, it's not a problem with it not powering on, it was powered off (at the switch on the back of the printer) and have been told it started doing something on it's own for a short time. Without any interaction from anyone or the power switched being moved to 'On'
-
Hi,
My s5 was powered off and someone who was in the room with it said it came on, made some noises (lights came on), then after a short time went dormant again?!
Does it perform some sort of self test/update on it's own?. Strange !
Sorry, scrub this, misunderstanding from the person in the room 😃😄

Thanks, just checked the price of the CC core !, over £320 !, ouch, that's expensive!, I am sure it used to be less than this ?!
-
I see a few places are selling metal infused filaments, Colorfab for example do a copper and a steel infused filament.
I am thinking about give them a try on my S5, has anyone tried them ?
I am assuming the CC ruby nozzle will be ok and also the standard hardend extruder the S5 has should be good to go ?
Cheers
-
Does anyone routinely clean the part cooling fans on the S5 ?, my old 2+ used to collect quite a bit of dust over time on the fans, i assume the S5 would be the same, however there appears to be no simple way to clean then, and no mention of this requirement in the maintenance schedule.
-
Has anyone tried using the Linear Advance plugin on the S5 ?, i have seen it in the market place and quite interested.
-
This makes more sense now, I was on 5.4 and must have flashed 2.11 back, will check the version numbers later. Not sure why my printer didn't prompt me to roll back. 5.4 is badly Brocken. It dragged the print nozzle accross the bed and dropped the bed at high speed into the end stop !!!, That should have never been released !, Just lucky my printer isn't damaged !!

since yesterday there is a "new" Firmware. And as you can can read in this forum the new one is the old one. Ultimaker makes a roll back to 5.2.11
Not sure I follow, I wasn't prompted to do a update. I just reinstalled whatever UM gave me when I said install latest. Are you saying this is back to a older version ?

You can downgrade firmware if you have an older version saved on a USB stick.i dont have the older version, is there somewhere to get those (incase it goes bad again)
Copy settings between extruders
in UltiMaker Cura
Posted
Is there a way to copy profile settings to the second extruder for the S3/S5. At the moment my profiles are all set for one extruder and when I dual print I have to manually copy all the settings over to the second extruder. Would be much easier to have a copy.
Thanks
