Ultimaker 2 not registering nozzle change

[trevorlaurencehill 0]

When I change the nozzle setting in cura and slice, the ultimaker still displays the file with 0.4 nozzle. I have changed it to 0.6 in cura but when you scroll to the file it says 0.4 and prints with bad extrusion. I have two machines. Both have the same problem. 1 has marlin firmware and the other has the bondtech firmware. Am I being dumb or can anyone else shed some light on why this may be happening?

Can you open the generated gcode file on your computer?

In the first few lines it should show something like:

;FLAVOR:UltiGCode
;TIME:791
;MATERIAL:2132
;MATERIAL2:0
;NOZZLE_DIAMETER:0.6

 

Verify this nozzle_diameter value to what you expect. I just checked with Cura 5.0 and this looks ok. I don't have a UM2+ printer here to check what the printer shows.

Is it an UM2 or an UM2+? @CarloKmight certainly know better but if it is a not plus printer (and firmware) could it have something to do with the fixed nozzle of the UM2? Either in the firmware or in Cura.
