6 Testing

6A) Plug the tool head into plug “1” and the thermistor jumper in plug “2”.

6B) Turn on the test printer and push the knob in.

6C) Scroll down and select “Print From SD”

6D) Select “Aero-Style-x1.gcode”

Note:
Two Meteor tool heads can be tested at once. If doing this do not use the thermistor jumper and plug in two tool heads. Then select “Aero-Style-x2.gcode”

The square fan(s) should always be on while the printer is on. After selecting a print the blower fan(s) should kick in briefly and the tool head(s) should start to heat up. Once the tool head(s) heats up the motor(s) will cycle. After that the blower fan(s) will turn on to cool down the tool head(s). .
