> [!IMPORTANT]
> **NOTE ON FLASHING THE FIRMWARE:**
> The Mightyboard uses an Arduino Mega bootloader but it doesn't do an automatic reset on DTR. To make the printer reset on DTR you'll need to flash it with a standard (or other) Arduino Mega bootloader.

> See [this guide](https://github.com/felipeksw/CreatorPro-Marlin-Cura/tree/main/Bootloader) for instructions on how to flash the bootloader.

### After Print Job Completes

```gcode

;disable all heaters
{% snippet 'disable_hotends' %}
{% snippet 'disable_bed' %}

M127 ; stop blower fan

```

### After Print Job is Cancelled

```gcode
M118 Print aborted!
M300 S1300 P200
M300 S880 P200

```

### Before Tool Change

```gcode
; Retract filament
G10
G10 S1

; Move Z-axis slightly
G91
G0 Z1

```

### After Tool Change

```gcode
; Un-retract filament

## Tips

### My nozzles are not offset in firmware!

It's possible that you may have different offsets saved in your printer's EEPROM. To fix this, you can either update your offset settings in the printer's configuration panel, or you can run the following G-code:

```gcode
M218 T1 X-34 ; Set the offset
M500 ; Save settings to EEPROM
```
