Printer not working after Cura update.

Recommended Posts

Posted · Printer not working after Cura update.

Hello everyone. I have this issue, hope somebody can help me: 


I have a Prusa with Marlin firmware. It have been working fine, up to I decided to update my Ultimaker Cura slicer from 3.2.1 to 4.6 (latest version until now). 


Now, printer doesn't work. This is what happens on Cura: 

- Printer gets connected as usual.

- Extruder temp shown a fixed 358°C value with extruder at ambient temp (about 20°C). 

- When bed heater order is sent from Cura, cooling fan starts (such as if ports were swiped). 

- When bed temp sensor is disconnected, extruder temp shows 0°C, and viceversa for the extruder temp sensor. 


What I found when tried to open Repetier Host: 


- When connected, it shows: "Extruder switched off. MAXTEMP triggered !". 

- X and Y axis works fine. 

- Z axis sometimes doesn't word. 

- Cooling fan works fine. 

- Bed heater and extruder don't work (heaters don't turn on). 

- Bed heater temperature is shown fine. 


What I have tried so far: 

- Send M999 code. Nothing happend. 

- Send M562 to reset temperature fails. 

- Send D0 and D1 to clear EEPROM and Reset. Echo: Unknown command. 

- Sensors are ok, I tested them and in both cases resistance is about 100k. 

- I uploaded again Marlin software to the Arduino (the version I was using and I was sure it was working fine). 

- I uninstalled 4.6 version and downloaded 3.2.1 again, but the problem is still there.


Be warned that I haven't made any change in the printer hardware or connections. Just updated Cura software and that made all this ha´ppenns. Hope you can give me some tip to help solving it. Thank you. Gabriel.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
