Hold torque during pause to change filament
How can I achieve keeping the motors active during pause to avoid moving their position during filament changes? I have changed the filament during some prints to change the color or to change the a newer spool, but sometimes the X axis is moved during the change. I'm now using some cloth clips to prevent moving during this change.
To pause the 3D printer I'm using the LCD menu ->pause, then I go to Move axis X, then I move close to 0. This change is manually and random since I don't know when the old filament reel is going to finish. The printer use Marlin as firmware with Ramps 1.4
In addition, please provide your printer make&model, and firmware if known.
Is
ADVANCED_PAUSE_FEATUREenabled in your printersconfiguration_adv.hfile?
There is aPAUSE_PARK_NO_STEPPER_TIMEOUToption included in there, which prevents the steppers from timing out during a pause, and may be more robust than a G-Code command if you plan to manually pause and resume the print instead of setting it up in the slicer.Alternatively, in the same file,
#define DEFAULT_STEPPER_DEACTIVE_TIME 120
#define DISABLE_INACTIVE_X true
#define DISABLE_INACTIVE_Y true
#define DISABLE_INACTIVE_Z true // set to false if the nozzle will fall down on your printed part when print has finished.
#define DISABLE_INACTIVE_E truecan be found. You may want to increase the
DEFAULT_STEPPER_DEACTIVE_TIME, or set#define DISABLE_INACTIVE_X true
#define DISABLE_INACTIVE_Y true
#define DISABLE_INACTIVE_Z true // set to false if the nozzle will fall down on your printed part when print has finished.to
falseto keep X, Y and Z engaged while allowing movement of the extruder stepper only.thanks, I will use this line #define PAUSE_PARK_NO_STEPPER_TIMEOUT // Enable for XYZ steppers to stay powered on during filament change.

Please describe how you activate the pause (e.g. menu button, or from g-code). Motors should keep their power during pauses. Also post the firmware you are using.
