Estimated time with Nylon

[Linusthehound 0]

I'm new to this so bear with me.  Cura estimated my print time at 3.5 hours with Nylon and 30 minutes into the print (Ultimaker 2+) the machine is saying 30 hours left.  I'm sure I have a setting off somewhere, any ideas?  Also, when choosing the material on the printer it didn't give me the option of Nylon?  Any idea why and what I can do about this?  I've only had this printer for about a week, got it pre-owned and still trying to figure out what I'm doing.

Hi @Linusthehound and welcome to the forums. I have split your question into a new topic.

 

Regarding to the problem, sometimes the estimated time changes during printing, but it should get more accurate towards the end of the print. Did you abort the print or did you leave it on?

 

When you select the material and the nozzle in Cura, you should get a warning if something does not fit. Nylon is supported on the UM2+ so it should print fine. Nylon is an advanced material though. You need to take some precautions regarding the adhesion to the build plate. Here are some instructions for Nylon:

If you use the latest Cura version, on the top right where you select the material an nozzle, there is a "Check compatibility" button/link. Click it and you'll be redirected to a Ultimaker page with a material/nozzle matrix.

 

Also in Cura, make sure to select the proper profile after you have selected the material.

Thanks, I used a glue stick for adhesion and it seems to be working very well.  Funny thing, I did abort the print job, let it cool off and restarted it.  Now it has a little over three hours.  I think the first few layers just take forever.  I had never used Nylon before, the guy I got the printer from gave me some.  From little I can tell so far I really like it....I will check the compatibility button next time.
