no connecting

Recommended Posts

Hi,

I finished assembling my Ultimaker. Now I´ve some problems:

If I switch on the Ultimaker without connecting the pc, all the motors makes ugly noises. I installed replicatorG, NetFabb and cura on my computer. No programm is able to find my Ultimaker. If I installed cura, I could see that now the arduino drivers was installed. Then cura tryed to update the firmware. The process started

but stopped afeter secounds. After this event each trying was aborted with the error " Is the machine connected to your PC?" It is. But it doesn´t work at all.

I tryed with Ultimakers supply switch on and off. No difference.

What can I do?

    • Ultimaker Cura | a new interface
      We're not only trying to always make Ultimaker Cura better with the usual new features and improvements we build, but we're also trying to make it more pleasant to operate. The interface was the focus for the upcoming release, from which we would already like to present you the first glance.

    • "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.
