2 nozzles

[savak001 0]

I've a UM2 with 2 Olsson Blocks, Titan extruders, new 0.4 nozzles, and Tinkergnome firmware, this setup has been successful before.

I have been wanting to print a nozzle dial that was downloaded from Thinghyverse but have run into some issues.

The dial is made up of two models merged in Cura, sliced and written to SD card.

 

The UM2 starts by extruding in the front left corner as normal but then the extruder gears grind for a few secnonds and the prints the first layer. When starting the 2nd layer the printer displays 'tried to print out of printable area' error, but the model is the only one and is in the middle of the heated bed.

However, when I print the main body in one colour using the same SD card, same slicing parameters and same printer the model is printed in full.

 

Any hints, help welcome.
