DescriptionSteps to Reproduce<The MIXING_EXTRUDER option is enabled. The system has two physical extruders and one mixing head, one heating element and one temperature sensor.
Expected behavior: If the option is enabled Command M115 Actual behavior: EXTRUDER_COUNT:1 Additional Information#define MIXING_EXTRUDER |
Configurations, please Please test the
So to be clear, is the problem with marlin or BTT ? |
this is no error or bug mixing is done virtually with vtools with 1 virtual extruder that is defined by the active vtool this is working as intended and this report should be considered user error. further more the system the user is describing is the singlenozzle system and not the mixing system that may be used on any mixing hotend. this miss understanding of the the 2 systems is wide spread i found my self explaining it daily to my community and even to this day it comes up alot. |

If the option is enabled
#define MIXING_EXTRUDER
#if ENABLED (MIXING_EXTRUDER)
#define MIXING_STEPPERS 2 // Number of steppers in your mixing extruder
The printer reports the M115 command
EXTRUDER_COUNT: 1
If I use the touch screen via the serial port, the printer does not detect the second extruder. I do not have the opportunity to control the second extruder.
Isn't this a mistake?
