Hi,

I have a Creality Cr-10, and I am trying to connect a Paste Extruder that I made. When I connected it to the wiring for the extruder nothing happened, so I reconected the wiring back to the original extruder. Upon reconnecting the original extruder I was greeted wiht a whole lotta nothing.

What causes this? How can I fix this so I can use my 3D printer again?

Thanks in advance

If you have Marlin firmware, there is a protection feature to prevent extruding anything until you heat the hotend. If you have not done that yet, I will heat the hotend to 180C at least before you try to extrude anything.

There are lockouts in the software that prevent trying to extrude when the extruder is cold. So it is likely that you have either mis connected the heater and thermistor on the extruder or broken one or the other wires going to those devices. You need to use a program that allows you to see the current state of the hot end. The temperature reading. Also look for any error messages. Manually set the temp to 200C and see if the temperature is reporting as changing. If its not going up check the thermistor and heater connections. Once you get good readings you should be able to extrude again. If you want to use a paste extruder you will have to disable the software lockouts in the printer control firmware. This might be easy just an extra line in the Gcode or you may have to reflash the firmware.
