Disable temperature control at cura (2.6)

[chrii 5]

Hello guy`s,

I want to use cura also on my old non UM printer.

At this printer i want to control the temperatures manual.

i disabled the "heated bed" to get rid of the control at the bed, but i haven`t found any similar option for the extruder to disable the control.

Also setting all (possible) settings to zero did not resolve my problem.

any idea how i can disable it ?

sincerly Chri

Set the extruder temp to zero?

...later...

No, that would just set the temp to zero when the print starts.

Edit the gcode and remove the temp settings.

You need to define your printer as using RepRap-type gcode, i.e. in the Printer Settings panel, select Gcode Flavor = Marlin/Sprinter or other non-Ultimaker type

That will expose extruder and bed temperature settings in Cura.

thats what i`m doing at the moment, i have to edit every gcode file, but it is annoying to do this every time

other slicers do have a the feature when setting the temperature to zero they interpret this as disable the temperatur control/command, thats why i tried it out.

for sure i added my printer as "Custom FDM Printer" , and Marlin Gcode flavor, and the temperatur settings are all there, but i want to disable the control at cura at all not set it manually there.

Two options:

The easiest way is to set the gcode flavor to "Ultimaker 2". This will remove all material settings from Cura for this printer, including the temperatures. Note that it will also set the extrusion to volumetric and disable start & end gcode, as it expects the printer firmware to handle start & end.

Only disabling temperature control is a bit trickier, because it cannot be done from the GUI. If you create your own printer definition, you can set the "machine_nozzle_temp_enabled" value to False by adding this in the "overrides" section:

       "machine_nozzle_temp_enabled": {
           "value": "False"
       },

Thanks for your answer, but as you mentioned it already, extrusion would be volumetric what is not enabled on my printer, so i can`t use a UM2 profile for that.

i just installed Cura 2.6.1 but haven`t found where the printer definition is stored at all to search for that "overrides" part ?

is there also no option to export a custom printer profile ?

Hello,

i finally was able to create a own def.json for my printer.

i also was able to disable at least the M109 waiting for reaching the hotend temperature with :

 

"material_print_temp_wait": {

"default_value": false

},

But i still was not able to disable the M104 command, i added the following lines

 

"material_nozzle_temp_enabled": {

"value": false

},

also when using "default_value" instead of "value" the M104 command still will be written into the gcode file :(

Is there anything else that has to be changed to get rid of the M104 ?

Chri

[chrii 5]

does someone have an idea how to disable the M104 at the end ?

Perhaps it's in the end g-code of your printer? What printer are you printing with?

[chrii 5]

Hy Ghostkeeper,

i`m printing on my orca, and using my own start and end gcodes, which do not have the M104 command within.

Please post your def.json file on pastebin.com (or similar) and let us have a look

@ ahoeben, i uploaded it here

Try with

machine_nozzle_temp_enabled

instead of

material_nozzle_temp_enabled

. Also, if you use "value", you should enter a string, like so: (case sensitive)

       "machine_nozzle_temp_enabled": {
           "value": "False"
       },

Thank you,with machine instead of material it is working (or better said not working anymore )
