FeloGreen I emailed QIDI Tech about the changes to there latest model and if I could make some of the updateds to mine.
They said extruder is different but would sell me a new one for $55. Actually not a bad deal. They also said they went to a new chip on the controller board but my board has the same firmware.
Could you do me a favor and take photos of all of the different menu screens you have so I can compare them to mine.
Mine dose not say any thing about Qidi Tech or Sailfish like yours does.

Thanks
