DWC Java



  • I added a fan and set it up using the RRF config tool and installed it using DWC. Now, if I try to simulate or print I get this message. I have updated the firmware and DWC, tried previous working config files, and no matter what I do I get this message. Help! I'm not a software guy by any means.

    Which firmware version are you using on the Duet?



  • I just updated everything in hopes of fixing the problem

    Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
    Firmware Electronics: Duet WiFi 1.02 or later
    Firmware Version: 2.03 (2019-06-13b2)
    WiFi Server Version: 1.23
    Web Interface Version: 1.22.6



  • Redid everything using the RRF config tool and it seems to be working now.
