Hmmm...that's interesting. Can you please put your gcode somewhere and post a link to it? It it's not to disclose, you may send it to me in a PM.

What Cura version do you use and what type of machine have you defined within Cura? Do you have any dual extrusion option activated?

M109 T1 S0? So the extruder 2 doesn't heat.... Did you set the temperature for extruder 2?

Extruders don't work if their assigned head don't reach 170C unless you send a M302 to allow extrusion bellow 170C (it's for safety)

Well that gcode line it's weird

It should be

M104 S210 T1 ;set the heater 2 to 210

M109 S210 T1 ;wait for the heater 2 to arrive 210

but instead you have just M109 and set to 0 (edited), so it will 'just' wait for the heater to reach the temperature, but shouldn't set the temperature... so it will just wait and wait.. until the winter arrives XD

Change that

M109 T1 S0.000000

to

M104 T1 S210

M109 T1 S210

@neotko,

do you mean I can slice without using the "Select-Extruder" plugin then edit Extruder1 to Extruder2 in gcode?

Indeed. tinkergnome said it on the second reply. https://ultimaker.com/en/community/19329-cura-dual-extrusion-how-to-print-only-with-extruder-2-or-only-with-extruder-1?page=last#reply-133487

Just make a normal single extruder gcode and add a T0 for extruder 1 or T1 for 2. Just incase check that the heat gcode points to t0 or t1 as needed.
