[Cura 3.3 is out !!]

Same here on iMac :(

[Nozzle parking and oozing at end of print]

OK, I've loaded the firmware from Cura 2.5 but sliced a model using Cura 3.2.1 and all is good.  No oozing blob at the end of the print.  Most definitely looks like a firmware issue and NOT a Cura issue

Thanks all for replies.  I'll get to it today.  However, as it is also doing it on all old gcode files I would rather adapt firmware so it no longer does this than have to edit every existing file manually.

Work around:

You need either manually add "M25" before the M82 at the end of gcode file:

...............................

M107

M25 ; Stop reading from this point on
M82 ;absolute extrusion mode
;End of Gcode

...............................

or configure Cura (Preferences - Configure Cura - Printers - Machine Settings - End Gcode) to add two lines - copy the two lines into cura as they are:

M82 ;absolute extrusion mode
M25 ; Stop reading from this point on

 

At least this worked on my UM2(+)

 

OK thanks will try this.

Hello are yo7 using cura 3.2 on Mac ,

Yes, using 3.2 on Mac, but it is now doing it on gcode files created many many many months ago, pre Cura 3.2

[Nozzle parking and oozing at end of print]

Good idea.  I'll go find it.  Thanks.

[Nozzle parking and oozing at end of print]

Looking for some help, please.  Been using my UM2 for over 2 years with few problems.  However, about a month or so ago it has started to have an issue whereby at the end of every print instead of the nozzle simply moving to rear left and platform descending the nozzle will stop at the final print position, ooze material creating a large blob and eventually (after about 20 seconds) break away from the part and park the head and platform normally.  It is even doing this on gcode files that were sliced many moons ago and printed many many times with no problems.  So both previous and new gcode files are doing this.  Every single print and it is very annoying.  I am suspecting firmware and it does not matter whether I have sliced the file using S3D or Cura, same issue.

 

Any ideas?

 

Thanks

[Upgrade your Ultimaker 2 with the Extrusion upgrade]

Hmm, me thinks they are trying to push people to buy complete new machine. Way too expensive (additional redundant parts) in my book. I'll hold off and may just get a U2+ at some later point (damn I've succumbed to their tactic )

[Control Wheel Spindle]

Thanks, but it's the aluminium spindle I need not the knob.

[Control Wheel Spindle]

Thanks iRobertl. Unfortunately that has made no difference. I have tried ever so slightly bending the spindle but realise it is very soft (aluminium) so don't want to make it worse. It definitely needs a new spindle so still looking for one.

[Control Wheel Spindle]

Good point.  I can see when turning the control wheel that it is off centre and wonky, Definitely the spindle. Need to get hold of a new one. I'll try support as the machine is only 4 months old.  Thanks.

[Control Wheel Spindle]

Does anyone know if it is possible to buy the control wheel spindle.  The control wheel on my Ultimaker 2 is slightly off centre and can be seen when spinning it.  In fact, as I turn it the wheel catches on the lower right side of the housing and makes it difficult to turn.  Others I have tried the wheel spins freely but not on mine.  I believe the spindle is slightly off centre so need to source another one.

Thanks.
