Nettoyage automatique de le buse avant impression

The Start G-code and Marlin have been modified so that the printer performs a nozzle cleaning before printing. The nozzle rubs against a piece of wipe-off material... In the Marlin Configuration.h file: Change the rectangle in which probing is performed to place the nozzle as close as possible to the edge (left or right?!) where probing ends. You need to place the wipe support next to where probing ends and in line with the nozzle passage. Ces values represent the position of the sensor!// set the rectangle in which to probe#define LEFT_PROBE_BED_POSITION 50#define RIGHT_PROBE_BED_POSITION 250#define BACK_PROBE_BED_POSITION 250define FRONT_PROBE_BED_POSITION 50 Change the height during movement between probing points, my support measures 15/16mm with sopalin and I set it to 13mm... #define Z_RAISE_BETWEEN_PROBINGS 13 //How much the extruder will be raised when traveling from between next probing points In the Start G-code (example with mine):G28; home all axesG29; auto bed levelingG91 original position for next codesG1 Y-100 F4000 the plate recedes by 100mmG1 Z11 F4000 the nozzle rises by 11mm to position itself at sopalin levelG1 Y-70 F5000 cleaning begins, the plate recedes by 70mmG1 Y40 F5000 the plate advances by 40mm etc...
