  • First try without filament so no forces are there. End
    M302 S1
    to allow cold extrusion, otherwise moves are blocked since extruder might be too cold.
    If it doe snot move open eeprom in host/server and check the weights. Might be that your wights are not set or steps per mm are not set in eeprom. Both would also prevent extruder moves. If you never have changed eeprom you can recopy from configuration.h settings with
    M502
    M500
    and try again. Especially if you had a version without that nozzle uploaded before these settings are often not complete.
  • found out where the wire was wrong with ... but I would like to make a macro. where I move the filament 800 mm to my nose. it can not, can only move it 100 mm with g01 e100 f2000 have tried to write g01 e800 it does not work .. what do I do there?
  • Firmware has a protection for long extruder moves. These are normally wrong and come from a print ending with a position like E8283 and then someone wants to extrude 10 mm with E10 meaning 8273 mm backwards:-)

    Simple solution is split it, especially in a script just du

    and you have your 800 mm move.
  • I can not change that protection? .. should use it for my mks tft 3.2
  • Sure you can of course also increase EXTRUDE_MAXLENGTH to match your maximum wanted extrusion.
