Fans turn on despite being unchecked in Cura 2.1.2

[LePaul 354]

Is this just a bug I'm experiencing or a known issue?

Doing some nGen test prints and they advised no fans.

Unchecked the Enable Cooling Fans and saved to SD card. Ran the print...fans turned on I was able to shut them off via the Ulticontroller but, of course, it should work in Cura

I tried it with my RepRap style Printer, and it omitted the M106 command from the gcode when I unchecked that box.

So it could be machine/json file dependent.

Also, look through that fan-off gcode for M106 to ensure its in there or not.

Also, does the fan turn on immediately or after printing the first few layers?

P.S. I just tested it with the Ultimaker Original printer profile and the M106 255 is on ;Layer:1 with the Fan enabled and nowhere in the gcode when I uncheck the 'Enable Cooling Fans' box. Let us know what you find.

My fans turned on when it hit layer 0.5

Disabling fans in Cura 2.1.2 works fine on my UM2.

[LePaul 354]

Not one mine....tried again.

[Dim3nsioneer 558]

But they don't run on the first layer, do they?

[LePaul 354]

No, not the first few layers...which is expected behavior

But turning on at layer 0.5 when unchecked in Cura...shouldn't do that

@nallath - I think this is a simple cura 2.1.2 bug that happens only with UMO (non ultigcode). Edited July 25, 2016 by Guest

Only with UMO?

Well...Mom always said I was special
