The last test involves checking the basic function of both the hot end heating resistors and the
heated bed. For this test, you're only going to turn them on long enough to verify that they're indeed
heating up as they should.
Fig. 2.2-9: Manual temperature controls.
We'll test the hot end first. In the Extruder Temperature Override section, click in the
"Target:" box (where it reads 0.0) and type in "200" and press ENTER or click on the SET button that
appears when you begin typing in the field.
Once you see the "Actual" temperature ("19.8C" above) begin to climb, wait a few seconds
and the click the OFF button to turn it off. Perform the same test with the heated bed by setting the
target temperature in the Bed Temperature Override to 50. Note that because the bed has such a large
surface area, it will heat much more slowly than the hot end.
You'll notice that after you turn the heaters off that the temperature will continue to climb for a
short time. This is normal behavior. It' just like a burner on a stove. When you turn it on for a short
time and turn it off again, it'll still continue to heat for a short time until the surrounding air can cool it
down. As the bed heats, you should see the "BED HEAT" LED illuminate. If it doesn't and you see
the bed heating on the LCD, check the polarity and wiring of the LED.
Okay, now that you've spent the last 5 minutes (Who am I kidding? You've been poking at it for
at least an hour, giggling like a little kid. Your dignity is the first casualty of having your own 3D
printer. Don't worry, you're in good company.) moving the hot end around and seeing how it works,
now it's time to get it calibrated so you can begin printing your army of squirrels and Yoda heads!
In order for the mechanical calibration to be accurate, we need to do the steps with the Rostock
MAX at operating temperature. This means that both the hot end and heated bed must be at the
temperature they'd normally be at while printing.
