Disable print removed confirmation message

Recommended Posts

Posted · Disable print removed confirmation message

Hello,

 

Is there any way to disable the print removed confirmation message on the ultimaker 3? I never forget to remove my print but do forget to press the confirmation message sometimes, as it takes some time to appear. And the next print i send via wifi won't start after i press the message. Maybe there is a way via ssh to disable it? Or at least a way to confirm it remotely?

It is a safety feature to prevent starting a print when possibly an object is still present on the build plate, this would cause mayhem.

 

For the above reason we never created a way to overrule this feature but more requests are coming in, so perhaps in a future firmware update...

 

How daring are you to make changes on the printer itself? Since you mention SSH I assume you have some Linux knowledge?

On the printer is a configuration file where you can make low level changes, but there is no official support for this modification.

In the file /usr/share/griffin/griffin/machines/um3.json there is at line 149:

    "PRINT": ["print.printProcedure.PrintProcedure"],

Change this to

    "PRINT": ["print.printProcedure.PrintProcedure", "cleanup_step": "false"],

 

THIS IS NOT AN OFFICIAL SUPPORTED CHANGE! 

In fact, I don't have a printer here and didn't test it working.

Unfortunately the modification does not work.

The clickwheel led keeps blinking and the printer won't boot. After removing the extra value the printer boots up again. The printer has the latest firmware (5.2.11.20190503).

 

I do understand the importance of the warning, especially for more chaotic places like schools or workplaces where more than 1 person is using the machine. But for me it is only an extra step that makes my workflow more difficult and time consuming.

Sorry to hear the modification didn't work.

Instead of posting another change that might not work either, you'll have to wait for me to return home later this week. Perhaps I can figure out another change but want to test it out on my machine first.

I found a solution that worked.

 

In the file: /usr/share/griffin/griffin/printer/procedures/print/printProcedure.py

Add "cleanup_step = False" after line 103 (cleanup_step = arg.get("cleanup_step", "True") == "True")

cleanup_step will be always false now regardless of what it reads in the configuration file.

There should be 8 spaces before cleanup_step, 2 tabs won't work.

Optionally you can also add "allow_reprint = False". This disables the reprint message after aborting a print.

Hi

 

One intermediate solution - put a button into the Cura / monitor / remote manager interface to clear the message. More or less:

 

User goes to load the new print via Cura

Notices the "is build plate clear" warning 

Looks at the camera and sees that the plate is empty

Hits the button to clear the message 

 

Still "safe" and it eliminates the long walk down three floors to push a button on the printer. 

 

Indeed I *have* started a print on top of an old one. The result was not at all pretty. The damage to the printer was not massive but it did take a while to fix.

I almost printed on top of another print because there were 2 print jobs in the queue. Still prefer being more careful over having to dismiss the message every time. It would indeed be nice if it was possible to dismiss the message in cura. However you can't always see the object on the build plate if the object is short on the ultimaker 3 extended. Maybe with utlimaker 3 it is always visible. A warning without the camera might be good enough.

Hi

 

I run a second camera on my UM3ext because you really can't see everything with the one stock camera. 

 

Generally when I see the message, the response is  "I took it off, it's right here  in my hand". There is no need to see the build plate 🙂

I do agree that this message can ben somehow annoying... There's a camera on the ultimaker, could'nt the system worke with some image recognition? (Yes I know that's a lot of work... But ultimaker printers are really expensive these kind of feature would help to explain the price)

 

What I also find annoying is that if I confirm the print removed message before powering off the printer, when I reboot it the message is back... And while the boot sequence takes really long I sometimes go to make something else and then forget to clear the message...

Hi

 

Did that image recognition stuff for a living in another life ( = *many* years ago). Getting it to work right with the limited camera view would mean moving the build plate while shooting pictures. The CPU in these printers really isn't very big. I doubt you would get the job done.

 

For great big prints - sure, you can spot them. For a thin print of a couple layers .... not so easy. Throw in things like tape on the build plate and it all gets really hard.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
