## Heating Modes

### Active

An "Active" heater means:

1. The tool associated with the heater is ***selected and is tool used to print***. All other tools will display a "standby" message below their heater (even if its the same heater).
2. The heater ***can*** start heating, to given active temperatures.

### Standby

A "Standby" heater means:

1. The tool associated with the heater is ***not selected***.
2. The heater ***can*** start heating to given standby temperatures.

### Off

An "Off" heater means:

1. The tool associated with the heater is ***not selected***.
2. The heater ***cannot*** start heating.

### Fault

A "Fault" heater means:

1. The tool associated with the heater is ***not selected***.
2. The heater ***cannot*** start heating.
3. The heater will not change to a different state, unless the fault is addressed. 
4. See [Heater Troubleshooting](https://promega.printm3d.com/how-to-troubleshoot/heater) page for help.

Hit "Enter" key.

### Using G-Code

#### There are two ways to heat the bed: Fast or Slow

1. Definition of ***Slow***: Set the bed temperature. All future G-code commands ***will not be*** executed immediately. It will wait until the bed reaches temperature.
2. Definition of ***Fast***: Set the bed temperature. All future G-code commands ***will be*** executed immediately.

Navigate to the "G-Code Console" Tab

#### Input Code (Slow):

```
M190 S75; This sets the bed temperature to 75 C
```

#### Input Code (Fast):

```
M140 S75; This sets the bed temperature to 75 C
```

### Using G-Code

#### There are two ways to heat the extruder: Fast or Slow

1. Definition of ***Slow***: Set the extruder temperature. All future G-code commands ***will not be*** executed immediately. It will wait until the bed reaches temperature.
2. Definition of ***Fast***: Set the extruder temperature. All future G-code commands ***will be*** executed immediately.

Navigate to the "G-Code Console" Tab
