Bed Mesh also cannot compensate for mechanical and electrical issues. This method will allow you to find the speed/accel at which your motion system begins losing steps. First try with defaults. Notes: For delta set bed size to 0 for x and y. Hook up the BL-Touch "servo" connector to a control_pin according to the BL-Touch documentation or your MCU documentation. Most folks probably haven’t even heard of it but it may in fact be j The main reason for this calibration macro is to get a filament and slicer agnostic way to calibrate the flow extrusion multiplier using simple measuring tools. for OrcaSlicer: SET_RETRACTION RETRACT_LENGTH={retraction_length[0]} RETRACT_SPEED={retraction_speed[0]} UNRETRACT_SPEED={retraction_speed[0]} UNRETRACT_EXTRA_LENGTH={retract_restart_extra[0]} Ecency Ecency I found what you are referring to. This macro is parametric and most of the values can be adjusted with their respective input parameters. Then one can just run START_PRINT and END_PRINT in the slicer's configuration. Choose the Pressure Advance option. Maximum Retraction Count: 10. They worked fine but was useless as some materials print fine with z-hop and other without, so I still needed to reslice.
