Problem connecting with 0035

Recommended Posts


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.

      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.
