Since we have checked for proper operation of our thermistors, we may now check our heaters.

On the Machine Control page, enter a number in the "Active" box for each heater. Start off with a low number such as 35°C.

Select the drop down box next to "Tool 0" and click "Select Tool".

You should see the corresponding temperature begin to rise. It is possible that it will overshoot the set temperature a bit, this is OK.

Complete this step by selecting "Tool 0" and "Deselect Tool" to put the tool into standby.

Repeat this step for the bed heater.

WARNING: If you enable the heater but do not observe an increase in the temperature reading, turn off the controller immediately and check your wiring.

It is recommended that you tune your heaters after ensuring their functionality.
