UM3 keeps trying to start a print while I try to troubleshoot

Recommended Posts

I started a print but noticed nothing was coming out of the nozzle, so I aborted to troubleshoot.

Every time I try to do something (I'm trying to move material through the nozzle to check it), the printer just re-starts the print, right as I am trying to do something else. I restarted the printer several times, went to Material>Move, but over and over, the printer just randomly tries to re-start the print in the middle of heating the nozzle to move material.

 

Of course my first question is: what is going on and how do I stop it?

 

My second question is: why are there so many screens that only offer one option? I feel like there should always be a "back" or "cancel" option, but frequently during troubleshooting or setup steps, the only clickable option on the screen is "continue". As far as I can tell, the only other option here is to cut power to the printer, which seems inelegant at best and harmful at worst. What's the deal with this?

 

Thanks!

You may have some prints lined up in your Cura Connect print queue. To check this, navigate to the monitor tab in Cura and you should see an option to view your print jobs. Once the Cura Connect page opens, you should be able to click on the three dots on the print and abort/remove it from the queue.

 

You can also do a full Cura Connect reset on the machine as well. This is found under System-->Maintenance. As a note, this will also remove your printer from its network group.

Hi Priddy,

 

I don't use Cura Connect (exactly for reasons like this that make simple hardware connections much easier to manage).

 

I suppose I could have tried just removing the USB stick. I ended up doing a factory reset, which solved the initial problem, but then while loading the materials in the UM3's system, it kept throwing errors that there were "too many materials" and then when I tried to manually select a material, it kept bucking me back to the "too many materials" error screen. Again, each of these screens only had one option to continue, no "cancel" or "back" option. I had to unroll each spool so that the NFC chips were 2' away from the machine, then bring only the one I was loading close, then back again.

 

Is there a way to just turn off the NFC? Buggy features are worse than no features. I couldn't find a simple way to do this in the machine settings.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
