ultimaker 2+ extended filament problem

[lysaer 0]

Hi there

I have an ultimaker 2+ and an Ultimaker 2+ extended

Both of these were originally non + models that I brought the kits for and upgraded.

My issue is that the ultimaker 2+ prints with no issues at all and the 2+ extended was printing fine and without changing anything it is now having huge issues with the filament slipping and not being drawn through.

If I use the same settings on both printers, printing the same file, using the same roll of filament, the 2+ prints fine and the 2+ extended just struggles to pull the filament though.

I have tried adjusting the screw to no avail, it just seems like it is not gripping on the knurled bolt inside.

Help would be greatly appreciated please

Hi Lysaer,

Since you've upgraded both printers to the + version yourself, I'm sure you find the problem.

When you said it's weak, do you think the stepper is weak or is it the feeder tension you think about? Also you said that this issue occurred “kind of overnight”, there might be an electrical issue.

You need to find out if the feeder motor is weak or not. Load a filament and try to hold it after it is entered the Bowden tube. You may see feel if the stepper is weak and step back or if it just start to eat into the filament.

You may also have a look at the current setting for the feeder in the menu at the Ultimaker controller, just compare the UM2 and the UM2-Ext.

Btw, if the feeder spring is too loose, it will eat into the feeder.

Good luck in your findings.

Cheers for the info dude

Finally fixed it after much fiddling.

Decided to take the feeder off and found out instantly what the problem was.

The cog on the end of the motor had slipped back, so only the face of the teeth on the motor cog was touching against the face of the teeth on the feeder, so when pressure was being exerted the cogs would just slip.

pulled the cog back out so the teeth met up and now it is perfect
