je pense que j ai trouvé ,c est tout nouveau pour moi , j ' essaierai demain pour voir si je peu calibrer
pour info j ai trouvé ça :
• We need to adjust the offset from nozzle 1 to nozzle 2(Fig 1 ) since there may be some errors in the installation process.
• Step 1. Ensure you know which one is extruder 1 and extruder 2, and you have connected extruder motor, hotend and sensor 1& 2 wire to control board properly. • Step 2. Copy the file “R2_Test_Block.gcode” to SD card ,then insert SD card to machine and start to print it. • Step 3. Adjust the offset of extruder based on the printed object. The process as illustrated below. 1. Press MIDDLE button to open the menu. 2. Enter configuation-->extruder. 3. Move the arrow to “Select extruder 2” and press right to select it. 4. Adjust “X offset” or “Y offset” according to the measurement result(Refer to the table). 5. Press LEFT button to exit and move arrow to “Store to EEPROM”, press RIGHT to save.
