Cura 15.0.1: Pause at Height, Change Material Issue

Recommended Posts


Yesterday I updated cura to 15.0.1 and with that the update for the Ultimaker2 itself.

I saw they added a function to change material when using pause at height! (I use it alot!) But when I used it I noticed that when your done changing the material it retracts just like normal but does not compensate for it when you resume the print!

This would not be a problem if there was no power provided to the stepper motor and you could just push the material the few mm it needs to start printing right away but this wasn't a possibility.

So the problem it the material doesn't catch up with the print maybe 20-30 seconds after you click resume print!!

is there something I could do to fix this or just wait on another update?

The material change wizard makes an "end of print" retraction of 20mm.

The default for the plugin is 5mm... this is a huge difference...

So - what happens...? The plugin retracts 5mm and pauses the print. The material change wizards retracts 20mm at the end of the change process. After resuming the plugin (respectively the gcode) reverts it's retract of 5mm... (needless to say: it has no clue about the other retract value).

The solution: change the retraction amount for the plugin to 20mm and it's fine again...(after reslicing of course...)

To tweak it a bit further: i noticed still some oozing during the pause and got better results with even 21mm.

BTW: if one uses the pause function of the firmware: it makes an additional retract with the amount of the "normal" retract setting (the same as during a print) - but this is another story....

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
