3D printing nozzle is not heated

Hello I tried 3D printing with swift pro. But the temperature remains between 30 degree and 50.6 degree. Strangely it displayed just two kind numbers, 30 degree or 50.6 degree. I attached its monitoring window image. How long time does it take to be heated up if it works properly?

It should work in less than 5 minutes. Would you please upload a picture of the connection? That would help a lot to find the problem. Thanks

I checked the connection issue, known as pin mismatch problem several times. But I think there is no problem with the connection.

So it seems the hot end is broken. How about the other functions like laser or blockly?

I checked laser. Laser modules work but its motion is very strange.

Any videos or laser engraving pictures? That would help a lot, thanks
