Filament change

edited August 2017 in Questions & Answers
The filament shift, Z axis goes to 0
Resulting in plastic accumulation fused under nozzle
Where it is possible to change the setting

Only when the system is switched on

    Only when the system is switched on for the first time

    I don't think we are sending z position at all for filamentchange. It might come from firmware aswedo not send z it might use last z which then seems 0 in firmware also if it is at a fifferent level. You could check in log which commands got send so it is more clear why it happens.

    These are the commands
    Use only for changing the ABS-PLA-PETG coil
    Not during printing
    My fast length is 750 mm
    Slow 18 mm

    Looks like server is comstntly sending positions. Is not what i wanted. Have to look into the sources when i'm back.
  • RepetierRepetier
    I have checked the code and in the current version filamentchange does not move the extruder at all. Are you using an older version then 0.86.2 ?
  • maralbmaralb
    I'm always upgraded to last version
  • RepetierRepetier
    Do you have any filament related scrips in server that would explain the coordinates?
