The diameter of the "screw" you say must be equaled to filament diameter.

Is the extruder moving with no filament?

Currently, I am stuck with trying to get the extruders to run. I have tested the drivers and motors by swapping them with a working axis and they all test good. I have set the temperature of the extruders to a working range, but still no luck. I get the Protection error message when the temp is set...

Either, because it will back to 0 V when you rotate too much. So you need a multimeter to test the voltage between screw and GND.

as you can see in the picture, there is only one led on.
And i checked the microstep setting too: there are 3 jumper

Over high currect caused 10A fuse burnt, you need to replace a new fuse.

Hello, u had right the heating wire must be broken inside the hotend because when i metered the cables individually i actually had a mesurement 11696775_10205807146711106_208852609_n.jpg 11714352_10205807147071115_436681642_n.jpg so i guess it needs replacement, about the fans as i told you both go...

Is there remaining tin on board?

My printer is fully functional with a few exceptions. My autoleveling is faulty - My manual controls work perfectly, but when I send the G29 command the hotends try to leave its own frame and then dances around in a circle while increasing height in an upwards spiral... I tried to print a calibrati...

There is a tool that can remove the melted tin:

I get a reading of 87.8 kilo-ohms from the bed thermistor when I turn on the machine without running the program. But now the error on the display reads "Err: MINTEMP" The bed thermistor looks fine, when the temperature is 25 degrees, it's about 100k ohm. Please check if extruder thermistor is well...
