Bambulab X1C Extruder and Noozle Test

This file is made for an X1C and should be printed from the SD card, not the slicer.

This file assumes a pei plate and Bambulab PLA, but will work regardless with any Plate or material that will have similar temperatures to PLA.

It will:

1. Print a small disk at the center of the plate
2. Lower the plate
3. Extrude 333mm of filament.
4. wait 90 seconds (during this 90 seconds you are supposed to reach inside the printer and grab the extruded filament, I suggest waiting 40 seconds to let it solidify)
5. Raise the plate, clean the nozzle and finish

The goal of this is to have a reference to measure if the extruder is failing or the nozzle is clogged. 

You will need a precision scale and with PLA the weight of the extruded material should be noted and archived for when things are not so ok.

The weight should be 1.00 grams, at least this is what I get on my printer with my test filament. You could have less or more according to the type of PLA. 

You cannot trust weight if you change filament. You have to take note of the weight of a filament to redo the test when things are not working and understand if the problem is in the nozzle (by replacing it) or in the extruder (seems like a lot are failing these days).

But you can use the length of the extrusion to evaluate if everything is working. 

First measure the diameter of the extruded filament. If is more that 0.4mm then nozzle is worn out.

Second measure the lenght of the extrusion.

As 333mm @ 1.75mm will have 800.959 mm3 of volume, whatever filament it is, the same volume at 0.4 diameter should be 6374 mm long, no matter what.

This is for an X1C printer only with 0.4 nozzle.
