Ultimaker S5 ER65 while using extruder 2

[Ogge500 1]

Hi!

We recently got an Ultimaker S5 Pro Bundle (Material station + Air Manager).

We’ve had no issues regarding printing with extruder .

However, when we are using print core 2, the story isn’t the same.

The printer regularly gets the error code ER65 without anything seemingly wrong with the printer. This happens at random (maybe once every 30 minutes or so)

The printer can be resumed again after the error code, but it is just a matter of time before the error comes up again.

I’ve done some troubleshooting to remove some variables:

• the error comes both when using PLA and PVA. So it cannot be the PVA having issues.
• I tested printing only with core 2 and the same error came. So it cannot be the switching between materials.
• Error comes both when using AA and BB nozzles.
• The printer is absolutely new with only around 60 ish hours of runtime.
• I have checked the extrusion mechanism and there is no debris found inside it.

 

I do have one theory, however I do think that it is unlikely the problem. The cables that go to the print cores are loose, not connected using some type of zip ties. Can this be the problem?

Hello

this is the usual procedure with PVA. With this PVA, ultimaker pretty much packs the maximum amount of trouble into the box. Unfortunately

The material can be damp. It very readily draws room moisture and is then not printable.

There are two cases for this. The material was already old when it came to you. Or you left it open in the room for a while.

In both cases you can stop the trouble immediately by buying a new roll of PVA from a specialized dealer.

You can also dry the material yourself. To do this, you should place it in the printer at 55° for hours.

I would measure it with a moisture meter. It should have 10- max 15%. And put it in a real filament dryer.

(Or buy a roll of Beakaway).

 

Another thing is the feeder. It should remain in the middle position even with such results.

It can always happen that the PVA gets jammed. Then to screw on the feeder only ensures that you regularly have a blockage in the system. A feeder that is set too high will cause a cork to form above the nozzle.

No, that's a good thing. Otherwise, you'll have problems with the cold connection to the print head. Unfortunately, this is all a bit sensitive.

Many greetings

Okay, thank you for the help regarding our PVA, which we do have tons of problems with.

However, the issue isn't with just PVA. The same error code comes when using two AA 0.4 Nozzles, and only using extruder 2 priting with PLA. Any ideas what might be the problem?

 

Thanks for the help.

Hello,

you could compare the pressure of the feeder right / left. Sounds like it is forming a cork.

Whereby I can not exclude other technical causes. Vl. it helps or another has still an idea.

Many greetings

Hi!

they are the same.

I can press the resume print button without any problems.

Have you reached out to your reseller? They should be able to help you with this.

The cable to the printhead should be attached to one of the bowden tubes with clips. Are these clips missing on your printer?

Anyway: it cannot explain the ER65 problems, since the filament flow sensor is located in the feeder on the back of the printer.

I have not reached out to our reseller yet.

Okay, the bowden tubes are loose at the moment. So i’ll try that!
