Problem during printing (Ultimaker Original)

[Max83 0]

Hello,

With my Ultimaker Original, I can't print objects correctly.

At the beginning of the printing, everything works correctly, the object begins to be visualized. But

It's only after nearly a minute that the impression shifts and no longer follows the right trajectory.

I've fixed the feeder, I don't see where the problem comes from.

Here is attached a picture of an impression.

Hoping for an answer

Can you check if the fan of your electronics on the bottom of the printer is still working?

Thank you ! Indeed, the fan on the bottom of the printer wasn't working.

If I change it, will the problem persist ? Or now, need i to change the motors ?

see what happens if you fix the fan, usually it works again (happend to me a couple of times..)

The fan don't works correctly, I will change it. But, do I need to change the electronic card ( or the motors ) too ?

[peggyb 169]

do you know why the fan doesn't work? Did it work before as it should be?

In my situation in both cases (2 different printers) there was a loose fan wire underneath and after readjusting everything worked again. Why or what would you change about the motors?

I guess that the motors are loosing steps if they get too hot...
