It's a Shrooommy! Dual Extrusion Print

[Ghene 24]

I've printed a mushroom mummy.
 
This is my first dual extrusion attempt.  Got the model from here....

Add followed the instructions.

What did I miss? 

?

Can you post your project file? Make sure to use "Save Project" so it will have all the models in position and the settings intact.

Erm.. I already started a different print ? 

[kmanstudios 1,120]

How would that stop you from using Cura to output a file? Mystified here....

 

[Ghene 24]

I thought you mean the actual file with it's settings that resulted to this print.

 

[kmanstudios 1,120]

yes. But are you using cura?

 

[Ghene 24]

this?

UM3E_Shroom_Dual_Extrusion_Base.3mf

That was it ?

I am going to have to look at this to see what went wrong, because it looks correct. All pieces in place, parts assigned to different extruders.

 

At first glance, I cannot figure why you would have difficulty. Is this the file you are printing right now?

 

Just took a deeper look. Again, I see no issues. Nothing that would produce the mummy wrappings you got.

 

Maybe it is just lonely and wanted its mummy? Arh Arh....

 

I will look again after I think about it. But, again, I see no missed steps or obvious issues.

 LOL. wrapped up like an Egyptian mummy ? ??
Thank you!

are you print cores calibrated? The only thing I can think of that would do this would be if they were not. The file looks fine. I am in the middle of prints right now, or I would directly test the file.

 

But, again, I do not see anything wrong. But if the two cores are not calibrated, it could be missing the surface of the previous nozzle's part and just not depositing on the model at all, thusly leaving a wrap around effect.

There is a feature called "draft shield".  Maybe you turned that on by mistake?

 

Always look at your print in layer view and scroll through all the layers to see if anything weird like this is going on.

 

Actually I'm thinking those are maybe travel moves?  Did you have retraction turned on?  maybe you were printing it too fast - I recommend you use the recommended settings or *thinner* layers but not thicker layers until you have printed 50 to 100 prints as thinner layers and other changes in settings can cause massive overextrusion like this on travel moves.

 

But still I'm thinking maybe retraction was turned off.

 

EVERY time you do a print, please save it as a "project".  In file menu: "save project...".  That way you can post that and we can look at it.  It will contain the model, where you positioned the model, the printer you are using, the scaling of the model/models, and all the settings.

pro tip:  If you override any settings - where it shows the profile drop down (for example "fast - 0.2mm") there is a star if you changed anything.  Click that star and click on extruder 1 and extruder 2 tabs and anything italicized in the middle column is your overrides.

Yes, I've done the calibration  for cores and print beds including doing the nuclear option.. First week with the machine and the amazing customer support from the GBIRE was very helpful.

 Thanks! Will try to print it again soon.

 Well, I've been printing icecream cone ring stands non stop after the failed dual extrusion attempt ? Will try it again after.

I do hope to find out what could have been the issue. But, I also understand the idea of moving on while the problem solves itself. Please keep us informed :) Love to learn things this way :)
