Dual Extruder: Only one Object print on the second Nozzle?

Recommended Posts

Posted · Dual Extruder: Only one Object print on the second Nozzle?

Hi Daid,

is it possible to print just one object on the specified nozzle?

I have different colors, and I want to print the one defined color.

What can I do to not to change the filament.

Thank you.

If you have only 1 model selected in Cura, and not configure your second Nozzle, it automatically uses the 'first' Nozzle.

Is this what you mean? Or do you want to set the '2nd' Nozzle as the first one?

I don't think that is an option in Cura.

Hi Sander,

yes, i want to set the '2nd' Nozzle as the first one.

Currently not possible yet by software in an easy way.

However, if you add a "T1" or "T0" in your start.gcode you switch the nozzle before it's used. So this way you could make different GCode files for the primary and secondary extruder.

I have added in my start.gcode:

M140 S{print_bed_temperature}

M190 S{print_bed_temperature}

M104 T1 S{print_temperature2}

M109 T1 S{print_temperature2}

The temperature of the 2nd nozzle is ok, but the 2nd extruder don't move.

If you just want to print one color in a single run, then it can be realised by a Cura Plugin.However, if you want to print multiple objects in one run with different colors, then it gets a bit tricky... but not impossible with some restrictions...

Well if you can figure out how to post in this forum you are good enough with computers to add a T1 command. Read about Marlin commands here:

http://reprap.org/wiki/G-code#T:_Select_Tool

Read the "select tool" section. The T1 needs to be on a line BY ITSELF. Not mixed with M104 command or other command. The first part of the line is the command.

By the way, doing a M104 *and* a M109 does not make sense. Read about those codes also. Basically the M109 waits and the M104 doesn't wait before moving on to the next command in your gcode file.

Oh man, it´s so easy.

M140 S{print_bed_temperature}

M190 S{print_bed_temperature}

M109 T1 S{print_temperature2}

T1

Thank you very much.

There. Now you are a programmer. It's official.
