Extruding Filament Test

[devamp]

I've been trying to get my printer to work for a month now after running into multiple problems.

I have a G2S Pro.

In the past when the hotend reached the correct temperature, the filament would start coming out of the nozzle. At that time the printer would not print.

Recently, when i tried to print something the hotends and bed would heat up to the right temp and go through the motions of the print, but nothing would come out of the nozzle.

Is there a way to test the flow of the filament out of the nozzle without printing something?

There does not seem to be a clog as i used 0.3mm drill bits and inserted into the 0.4mm nozzle hole with no problem.

Maybe something wrong with your extruder motor part?Have a look at this post:

You can test the flow of filament in Repetier Host or on your LCD "Prepare->Move Axis->E0/E1":

I am new to Geeetech Prusa i3 pro aluminum.

I have burned up two PFET tubes and not made one good print in over 30 attempts. 10 X 10 X 10 cube=5 minutes.
New metal extrude assembly because my plastic one was broken.
Nozzle temperature varied from 193 to 220 (indicated) during one print: 27 degrees C temp change.
Steam and plastic coming out of the hotend at 150 degrees C (indicated).

Measured the hotend with infrared pyrometer : when Prusa said 157 degrees Raytech said 197 degrees. Aborted heating. Not going to burn up another little white tube.

Both my thermister and heater are loose in the aluminum block. That doesn't seem right to me!

Hi,
Can you attach a video so i can learn more about your issue?Thanks in advance

FIXED! Printing really well now,

A small bit of thermal paste squeezed in around the thermister and the heater stabilized nozzle temperature to within one degreee when printing now.

thank you very much
