Incorrect detection of Quick-Change Heads

The BoXZY Interface always prompted "BoXZY Laser Head detected" in the Log. That is regardless whether or not a quick-change head is connected.

It was first appeared when I was checking the 3D Printing Head. After that, such prompt always appears even without any head connected.

How to fix this?

I have opened the back cover and found this...

So it was incorrectly done!?

The little red wire and the red one should be on the top side, right?

Answered! View the answer I have this problem too

Is this a good question?

After that the 3D printing nozzle never heats up!

Also the temperature indicated in the Log always at 989.5 degree-C!!!

Yeah, many of the very first batch of machines had the wires switched for the thermistor input. It's a good idea to switch them to the correct location as shown in the diagram (all 3 wires have to relocated).

All of the symptoms you described are the same issue. There is a short in your thermistor input somewhere (on the machine not within the heads) The machine will read 989C whenever the thermistor wires or leads are shorted together. It also keeps the heater from heating when this happens.

This temperature reading is also how the laser is detected. The inside of the laser is set to read at that temperature so the machine knows that it is indeed the laser plugged in.

All you'll need to do is carefully trace the thermistor wires and check them back to the board. My guess is the issue is at the connection point on the main board (red and white wire accessory input in the image below). The little red wire has likely shorted between leads. It will be simple to fix either way, As long as you do the checking and repairs with the power completely disconnected

*It's less likely, but not impossible for this issue to be caused by a power short (power shorting to the thermistor input) within the 3d printer head permanently damaging the Arduino board. In this case there would be no wiring short on the main machine and the short would be internal to the Arduino. In that case replacing the Arduino and fixing your 3d printer head wiring would resolve the issue. Replacing Arduino link

Awesome! Im glad you you able to locate it and change the wires to the correct location. You definitely want to upgrade that USB cable to one with Ferrites like this one https://www.tripplite.com/usb-2.0-high-s...
