Good afternoon everyone!
One quick request - would like to hear from anyone who has applied the new firmware to UM3 or 3X with Bondtech feeders. Is the modification process for the new steps the same?
Thanks in advance!
John
@JohnInOttawa I have two UM3X with Bondtech extruders. Yes the tweak is the same as for the previous FW. You need to edit the um3.json and another file but I don't remember it. I refer always to the Bondtech documentation
It works very well

@CarloK Thanks again for the reply.
UM3 stock doesn't have a flow sensor, so back port won't work. Nor do mine as I have Bondtech extruders on my two UM3E.

@V3DPrinting I already replied your same question in another thread. Summary: no, this value wasn't changed in the 5.2 versions. The last change is from April 2016 when it was reduced from 750mm to 700mm, that's the correct value for the unmodified printers.
@CarloK Thanks for the reply and sorry for the double post. I couldn't remember if I had posted it. I'll check my Bowden tube length then.

V5.2.17 was released today and fixes most of the known Active Levelling problems.
@CarloK The upgrade to 5.2.17 has fixed the leveling issues. I'm printing dual extrusion since mid August with that version without any issue.
But it has introduced an error in the filament loading and unloading procedures with a wrong length for the Bowden tubes. In um3.json, the Bowden tube length now is 700 mm. I think it was 760 mm in the previous version of 5.2.
Can you confirm ?
-
@CarloK v5.2.17 works fine regarding the dual extrusion.
But it seems that some parameters were copied from another printer : in um3.json the Bowden tube length is 700 mm. As a consequence, the filament loading / unloading procedures are not accurate.
If I remember well in the old FW it was 760 mm.

Thanks @CarloK !
I have upgraded my two UM3E to 5.2.17 from 4.3.3 in two steps without any issues.
The dual extrusion now works properly with this FW.
I have also implemented the tweak you've provided on mesh leveling but kept 9 probing points, so I'll be able to reduce the first layer thickness for fine prints.

2. I added the machine without it being upgraded. You could try this by removing the machines from cura and re-adding them.
If those don't work, please create a ticket on github, since it's much easier for us to keep track of things. The link is https://github.com/ultimaker/cura/issues/I have upgraded my S5 to 6.2.2, but it hasn't changed the behavior.
I believe the issue is on Cura for macOS
I will create a ticket

Done it and also removed all the files in the cura folder related to UM printers except quality changes, flushed cache, ...
No success.
I also have a Linux desktop, which isn't my primary desktop, no problem with the drop down list.
I have also noticed that the printer selection in the custom panel of the GUI is not working properly : when you change the printer, the list closes, but when you want to select another parameter, it opens again the printer's dropdown list.... Maybe it's related.

We haven't touched the feature since 4.2
So i'm going to need a bit more information about your system (including log files) to figure out what is going on.Hi Nallath
Thanks for the feedback
I am running Cura 4.10 on MacOS Big Sur latest version
It's a fresh install then imported my materials and profiles from a previous 4.10 installation and created two non networked printers (Mankati Full-scale XT Plus and a custom FFF to emulate a BCN3D Epsilon)
I don't have the full content of /Users/Library/Application Support/Cura right now, but here's the packages installed and the log file.
Hope it helps

Why do you use a host and a printer group, is there any advantage for you?
I mean when you don't have a group, just 3 standalone printers you can still select each printer in Cura and send the job to the printer you want.
I think the idea behind the printer groups was that you have a printer farm all of the same type and you just send a print job to the farm and the next available printer takes the job and print it. But as soon as you have a mixed environment it has no advantage in my option. But maybe I miss something....
Hi Smithy
As I have 2 UM3E the group provides the load balancing.
Also I can have a global view from the host cura connect (progress of files, cameras, ...)
To be honest I haven't tested stand alone printers as the group was promoted years ago, since I own more than one UM.
Maybe reverting to standalone networked printer will also solve a couple of issues regarding disconnections and corrupted files when loading a project were the printer is not the host.

Everything is in the title.
It is annoying and a roll back of that feature as already done in 4.1 or 4.2....
I have done a fresh install of 4.10, but the problem is still there.`
I am a bit old fashioned and don't use Digital Factory. Sending the files to the cloud is an issue for Data privacy reason with some of my customers .... Using a vpn to connect to the local network is providing the right level of functionalities and security.
So I am using the "print over network" feature with a group of 3 printers were the host is an S5 and two UM3E printers connected to it.
None are on the latest firmware and no good reason to upgrade
- 4.3.3 is stable on UM3E without any leveling issues on dual extrusion, which is a problem on 5.X versions
- 5.2.x works fine on S5 as I don't have any air manager nor filament cabinet. Being a V1 S5 I don't want to take the risk of bricking it upgrading to 6.X
So please roll back the feature.

I also have good experiences with Dimafix and I tried a lot.
I prefer the spray rather than the pen because the layer is more uniform. The drawback is that you need a well vent room to apply.
The pen is very good for small surfaces or touch up.

I'm having lots of issues of glass chipping while printing ABS as well. Material is standard Ultimaker ABS.
Hi Matt
Since my last post on this topic, the issue has been resolved for FormFutura ABS grade using Dimafix on the standard S5 glass plate.
You need to apply a regular medium thick layer of Dimafix and a hotbed at 80°C or more
When the print is finished and the glass plate cooled down to 45 - 50 °C it starts to pop up easily.
Be careful of your first layer height. Check that your print cores springs are at the right value (approx 900g to start moving the core when pressing it by the mount on a scale). If it's too weak then your first layer would be too thin.
-
No probs.
i have made a test with a bit more retraction and reduced temp for the first layer.
If it improves the oosing, I will try with a Z hop when retracted.
The latter should be the best option, but due to the oozing of the TPU, it is currently worse than no Z hop.

Try to set under Travel / Layer Start X and Layer Start Y to 0
and be sure to have a Skirt enabled.
Thanks Smithy
I had a try, but no impact on the preview. still the same tool path.

I made a mock-up project. So everybody can have a look at it.
Thanks for your feedback

It's always much more easy to help someone when he share his project for analyse. Attach a curaproject.3mf to your post.
Thanks for your reply.
Unfortunately I am not able to share the project due to the confidentiality agreement I have with my customer.
It is pretty much the Cura default 200 microns profile with Ultimaker TPU except the parameters I gave on my first post.
To clarify the point, I would like to force Cura to comb on the first layer instead of making retractions and straight move, except for islands of course.

Hi to all
I have an issue with a part printed in TPU 95A on an UM S5 where I need to print letters carved in the part. Due to the shape of the part, the face with letters must be on the build plate.
I have no issue printing the part with the letters at the right dimension (tuned retraction, no supports, some CAD tweaks, negative horizontal first layer expansion, combing on "not in skin", no z hop when retracted)
But I still have a line on the build plate when the nozzle moves over the letters when printing the first layer.
Z hop when retracted is worse because of the oozing of the TPU.
Thanks for your advices on how to tune Cura for that particular need.

The IDEX system won't work with 4.9.1 (or well, any version of Cura released by Ultimaker). BCN3D hacked that into their version and I think that's why they don't update.
Thanks Nallath !
I was suspecting the IDEX system to be a showstopper.

Hi to all
I would like to set up Cura 4.9 for a BCN3D Epsilon, using it only in dual extrusion mode (no duplication nor mirror mode).
I am using the BCN3D version of Cura, but it's outdated on many parameters and I would like to benefit from features available on Cura 4.x
Is it possible first to set up a dual extrusion system in Cura ? It wasn't possible on previous 3.x version of Ultimaker Cura
Is it possible to make it work with the IDEX system for dual extrusion prints ?
Thanks for your feedback.
David
PS : I know the BCN3D and Ultimaker version of Cura are forked ones with lots of hacking on the BCN3D one.

It looks like if I set levelling frequency to Always it resolve the issue on my machine. I'll do some more tests but if anyone else still have issues and test this, please report back
I had the issue with FW 5.X on my two UM3X with auto leveling frequency set to Always.
Changing the leveling frequency did nothing to the issue, except turning it off and doing a manual leveling (but it is tricky as it is temperature dependent)
The only workaround for me was to downgrade to FW 4.3.3. Since no more issues with dual extrusion prints.

I'm thinking perhaps the capacitive sensor is perhaps a bigger factor in levelling with the newer firmware?
Hi John
The issue is determining the right nozzle height for the 2nd (right) nozzle.
Both left and right are using the capacitive sensor to do it and left nozzle is always fine.
To me the issue is more a computation bug in the FW.
Nevertheless the sensing cycle on 5.2.x seems to be more accurate due to the fact it is heating the build plate, taking into account its thermal expansion. Unfortunately, it's not operational on UM3.

I'd apprecate an update on this - it seems to affect my UM3X and not my UM3 for some reason. Wondering if the latest firmware for the UM3X will fix this?
Thanks
John
Hi John
I do confirm that FW 4.3.3 fixes the issue on UM3X. Works like a charm since May 2020.
I haven't tested the latest FW, as Ultimaker does not put any penny in the UM3. Everything is focused on S line, and their non regression tests are nearly non existent.

10/16/2020.......Latest firmware and cura 4.7.1. Ultimaker 5S, ethernet connected. A week ago after latest update my printer disconnects after a few seconds in Cura. I can connect with the digital factory, but file sent to print does not show up on my printer. Has anybody fixed this yet?
I am still using Cura 4.2.1 because I had no disconnections over ethernet on my S5. Also I haven't upgraded the FW, still 5.2.11. But I was thinking of an upgrade.
In my case disconnections were linked to the creation of a bunch of "shadow" printers by Cura 4.3, 4.4 and 4.5 (all were a PITA regarding this weird behavior).
Printer were visible in the printer management tool, but not connected except one. That was messing up the connection.
Is that your case?
I had some calls with Ultimaker Team, but they were saying not to be able to reproduce the problem....

Material settings for different custom printers in Cura 4.11
in UltiMaker Cura
Posted
Hi to all
Maybe the subject have been already discussed, but I haven't found an answer yet.
Here's my question :
I have different type of printers : Ultimaker 3 Extended, Ultimaker S5, BCN3D Epsilon W50 and custom based on RRF (Duet3D)
I am currently using Cura 4.11 as a single slicer for all those printers, sharing the material database together and benefiting from the plugins and latests releases. (For those who are interested in how to use standard Cura for BCN3D IDEX, please PM me.)
Material parameters like Temperatures, Retraction settings, cooling have to be personalized per printer type.
For the Ultimaker family, it's well done and you have a set of parameter for the UM3X and for S5.
Is it the same for the custom defined printers ? Are these parameters individualized per machine ?
I ask the question because all the print profiles for custom defined printers are available when a custom printer is activated.
Thanks for your feedback !
