Extruder Motor

Recommended Posts

May day may day

We lost one engine! :eek:

Hello everyone,

that would be a nice, reaally smoothed version of my help request as I have been struggling with this ultimaker for days. I am exhausted!

This Ultimaker 1st version works fine except for the extruder motor. There is no way it runs. I use Cura 15.01

What I did:

1. I unplugged the extruder motor connector and connected to the Z output. I began to pring and the motor spins in both directions. Motor OK

2. I swapped the drivers (the Z with the Extruder) to check them. Drivers OK

3. I tested the coil of the E motor by connecting two pins and then the other two. It seems to work too.

4. Did a standard ultimaker firmware upload. No differences.

5. I bought five brand new drivers. Same thing.

6. I checked resistors, capacitors, connection from the E driver to the arduino board.

Is there anyone who had the same problem?

Pleeease

I did not know that the extruder motor does not run when the temperature set is too low.... and I have worked all this time unloading the filament with just 35°C !!!!!! :O:O

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
