UM2 Software Update

Recommended Posts

During my troubleshooting with my restarting printer i've tried to update the firmware via CURA.

 

While Upgrading the Firmware with "Automatically upgrade Firmware", it tells me that a communication error occured, following by the printer to quickly restart (LEDS on and off again).

 

Can this have something to do with the faulty PSU?

How long is the USB cable you're using?

 

Can you connect the printer to your computer successfully with other programs? (Pronterface is a good choice.)

 

It could be an issue at the board, but it could also be a cable issue. Super long cables can time out while trying to transfer the data. Have you tried more than one cable?

    • "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.
