First Layer problem



  • Having just rebuilt and recalibrated my printer I was having a lot of problems with first layer adhesion.
    I used the Duet setting up guide, but the nozzle always seemed to be to far from the build plate to adhere properly.
    I have adjusted this within simplify3d by adding a -0.15 offset. Problem is old Gcode files are now unusable.
    Is there a better way within duet, such as adjusting the sensor trigger height or some other way.



  • @Dave-Parry the z value in G31 sets the trigger value. If you're having to babystep down 0.15mm every time add 0.15 to your trigger value



  • I use a macro to set the G31 Z offset. That way if it ever changes, it doesn't affect the gcode files.
