Problem connecting with 0035


Recommended Posts

Posted · Problem connecting with 0035


Yesterday I built my Ultimaker.

It was already printing very good but I had RepG 0024.

Today I installed 0035 but I can't get it to work.

I can select the serial port but when trying to connect I get en IOException (screenshot attached).

Next I tried to upload new firmware but RepG just ends up hanging.

I know it is supposed to but I waited for 30 minutes, no result.

I am new to this, not quite sure where to go next.

Can anyone help me on the way?


I can install the Old 5D firmware but none of the Sprinter/Marlin firmware.

    It seems that Erik broke that link somehow.

    What I would advice is this:

    - Disconnect the UM from your pc.

    - Start ReplicatorG

    - Connect the UM, but do NOT try to start it in replicatorG.

    - Upload the newest firmware on the board.

    - Go to Machine, Machine Driver and select Sprinter/Marlin.

    - Connect the machine in RepG.

    The upgrading can also be done with older versions, however repG 34+ requires Marlin firmware to work properly.

    EDIT: Cura firmware also works with RepG, but you need to use the "Experimental Marlin Firmware" in order to make it work.

    Thanks for your reply.

    In the meantime I managed to get the machine connected met the RC3 of Marlin (Erik's build).

    But I have not managed to get anything decent printed so far with 0035.

    Just now I went back to 0025, reinstalled the 5D firmware and I get very good results.

    Also it seems with 0035 the extruder is not working.

    At a given moment, while it was printing I could rotate the cog wheel of the extruder.

    It felt like the stepper motor was not connected.

    Ok, in the meantime I found a solution.

    0024 did allow me to install the new firmware.

    When that was done I could use 0035 to connect to the machine.

    I must say the quality of my prints improved tremendously.
