Cura 4.9 & 4.10 : Unable to select the printer when printing over network to a host group

[V3DPrinting 11]

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.

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....

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 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.

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

cura.log packages.json.zip

Ok that makes sense. In my case when I tested the host group feature it was not really useful, because I only have different printer types, so nothing to balance.

@V3DPrinting I've just tried reproducing this on my machine, but for me the dropdown is selectable.

 

There are a few reasons that i can come up with as to why:
1. I'm on linux (which isn't helping you, but it might make things different)

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/

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.

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
