disabling a tool in cura
-
Hello,
i have a toolchanger with 4 tools (T0-T3). In cura they are listed with Extruder1-4.
I like to print a model with "only" 3 tools (T1-T3). But it seems not possible to disable T0 copletely!?I have disabled T0 (Extruder1) in Cura, but it picks up T0 everytime for the prime tower!
Also, when i define the primetower for T0 to 0 mm3 volume. It picks up the tool, heating it and do the move to the primetower and back to the dock...Can anyone help me?
Thanks in advance. -
It may help to share your Cura version and a sample gcode file. Your config.g and Duet firmware wouldn't hurt either.

Hi @cosmowave,
two things to check:
(both points are based on my memory, default behaviour might have changed but the solutions should still apply)- Cura is not very smart when it comes to multitool printing, it has "default extruders" for many features such as support, adhesion etc., and there might be some shady rules on which it selects the extruder - e.g. using the material with the "lowest adhesion tendency" as support, which is not even a setting that you can influence in Cura itself but rather in the material's .xml file. It's an Ultimaker thing but it makes life harder for the rest of us. Long story short, enter "extruder" in the settings' search bar and check that all extruders are set to the right tool. Often times I have the wrong extruder selected for "adhesion", so for the skirt of the print it selects another tool first before moving to the correct one.
- Cura also inserts some default Gcode aside from the "Start G-Code" into the beginning of the G-Code file, and there might be a "T0" in there just because. I have a "T{initial_extruder_nr}" as the last item of my Toolchanger's Start G-Code that can be set in the printer's settings panel. No custom G-Code for each of the tools.
hope this helps,
best regards, Niklas

@sonderzug @Phaedrux
thank you both for your answers. But i was not able to print with T1/T2/T3, without "touching" T0!
The only way was to define a printer with only 3 tools and use T0/T1/T2. -
@cosmowave I was able to print only with T1 on a dual head setup by deactivating T0 in Cura before slicing
