Retracting way too far after print is finished?

Posted · Retracting way too far after print is finished?

I just upgraded to cura 15.04 and now when I finish or abort a print my printer retracts the filament 20mm or more, removing it from the print head entirely.

I have to go in and manually advance the material before I can print again.

Anyone have any idea why this is happening or how I can fix it?

    Hi printrev, welcome to the UM forum!

    What machine do you have?

    On an Ultimaker Original, this rectraction can be found in the end.gcode in Cura. On an UM2 it is (hard)coded in the printer's firmware.

    It's an ultimaker2. It was working fine until I updated the firmware today.

    If it's hardcoded I suppose I could drop back to an earlier version. I'll try that if there is no other solution.

    Do i have to use Marlin with the Tinker firmware? and do i just simply click "install custom firmware" to fix the retraction after print?

    20mm is the default "end-of-print" retraction on the UM2 - from the start on...?

    AFAIK this is only relevant if you use Cura with the gcode-flavor "UltiGcode". Do you made any changes on this side lately? Which slicer do you used before?

    In addtion - there was a firmware issue - if you pause a running print and subsequently abort it the end-of-print retraction was doubled.

    This is fixed with Cura/Firmware version 15.04.1 (or later). I think, the current version is V15.04.3 - the last digit is important.

    Hi @craftee,

    if you want to install this firmware you can download the appropriate *.hex file for your printer (from the link above) and install it with Cura and "install custom firmware"...

    ...but... ...

    ...it still does not automatically fixes all printing issues... (i'm working on it... :) )

    I gradually made some minor changes on the user interface and - as a side effect - the amount of the "end-of-print" retraction is adjustable (V15.09 or later - Advanced -> Preferences -> Retraction settings)

    BTW: there was a short - but similar - discussion recently.
