2nd extruder activating during print

Recommended Posts

I have an UM3 and I don't use the 2nd extruder often, but I just noticed that during my print (of a single color print) my UM3 acted like it was changing materials (when it goes in the corner and starts to extrude) then did a lap around the skirt, then changed back to extruder 1 and kept on printing.  Anyone know what that's about?  Is that normal and have I just never noticed it before?

I am using Cura 3.1 and Extruder 1 is set for the build plate adhesion.  Hence why I'm confused.  It did it like after about 30 min into the print.  Just very weird.  I think it did it yesterday too because I was finding these burnt pieces on my plate like that had fallen off because when Extruder 2 was going the PVA filament was just curling and sticking to the nozzle.

Here's a file I know it did it on.  It seems to happen right after the first layer goes down from Extruder 1 completes, then it switches to 2 for some reason, does a pass around the skirt then goes back to 1 and keeps on printing.

 

 

It's tries to print a skirt with the second extruder.

I see that support is enabled (but apparently not needed?)), which one is the "Support Extruder"?

    • "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.
