The purpose of this test is to determine how well the Nylon extrusion system is performing.
The test extrudes a known amount of of Nylon. Based on the behavior of the machine during the test and the mass of this extrusion you can figure out if you're having extrusion problems.
First, the test will extrude a purge stream. Make sure to collect and discard the first extrusion.
Caution: The nylon nozzle and extruded plastic will be hot during this test. Be careful not to touch the nozzle or extruded nylon with your bare hand. Use the included tweezers to handle the nylon.
- In the utilities menu select Calibration Extrude Test
- Follow the prompts on the screen to begin the test
- The machine will home the Z axis and the Nylon nozzle will begin to heat.
- Once the machine has reached temperature the screen will ask the user to continue the test.
- The machine will begin to extrude nylon and purge the system.
- As soon as it is done purging you will hear it retract and pause for 2 seconds.
- During the pause remove the extruded nylon from the nozzle.
- The machine will start extruding nylon again. This is our test sample. Be sure to catch it with the tweezers.
- During the test listen for the plastic extruder clicking. If the extruder makes a clicking sound and the wheel jerks backwards the resistance in the plastic flow system is too high.
- Once the machine is finished extruding carefully collect the extruded nylon with the tweezers.
- Weight the second nylon flow on a balance with at least 1 mg accuracy. The reading should be between 0.1800 g and 0.2100 g.
- If the plastic extruder skips during the test, or the weight of the second plastic flow is less than 0.1800 g, please see the nylon troubleshooting guide.
