[Ultimaker 3 Extended printcore 2 problem]

Does anyone have a solution to this?

[Ultimaker 3 Extended printcore 2 problem]

For a workaround I added .2mm to the first layer.  This makes layer 1 of printcore 1 too thick, but printcore 2 prints good.

Thanks for the info.  #`1 and #2 would apply to both printcores, correct?  As I said before there is only a problem with printcore 2.

 

1. The Z limit switch looks clear - nothing blocking it.

2. This would change the level of BOTH printcores, which does not help.  Printcore 1 prints just fine.  I did not change the screws.

3. I reinserted 2 and it clicked into place.  The problem still exists,

My Ultimaker 3 Extended is having trouble printing with printcore 2.  I have auto leveled twice with the same result.  The nozzle is so close to the build plate that filament won't extrude.  It does not scratch the glass but the glue is wiped clean.  I have verified the nozzle is not blocked - it extrudes when changing or loading filament and I have done a cold pull with a clean filament end coming out.

 

Printcore 1 prints fine.  How do I fix this?

[gcode name options]

It would be very useful to have the estimated filament used in the filename (ie: partname_45g.gcode )

 

I am manually doing this now for items saved to print again in the future.
