Titan Aqua Marlin Configuration

Almost all printers use Arduino IDE to upload fresh firmware, so download it at https://www.arduino.cc/en/Main/Software

If your old extruder was ungeared, you'll notice that your new Titan extrudes backwards!

Flip the folowing line in the Configuration.h file from true to false, or vice versa: INVERT_E0_DIR

The next thing we'll have to update is your printer's E-steps-per-mm.

First, we'll start with a ball-park estimate of your E-steps-per-mm, and then we'll fine-tune it.

If you're using the standard Titan Slimline motor, start with 837 Steps-per-mm

If you have an LCD Screen:

Navigate to Control → Motion → Steps/mm → Esteps/m and enter your new E-steps-per-mm value.

Select Store Settings in the Control menu to save your settings.

Over USB Connection

Use a printer control software to connect to your printer. Send the command M92 E<your number here>to your printer.

Then, send M500 to store your settings

If you don't have EEPROM, or want your firmware to be consistant with your EEPROM:

Update the following line with your new value in the E-steps spot: #define DEFAULT_AXIS_STEPS_PER_UNIT {<X-axis> <Y-steps> <Z-steps> <E-steps>}. Upload your firmware as normal.

Load filament into your extruder, just until it is gripped by the drive shaft (you can't pull it out without moving the large gear turning)

Mark your filament at the top of the idler arm or PTFE tubing with a pen or permanent marker .

Tell your printer to extrude 100mm of filament. Use your printer's LCD screen, or send it: G92 E0, then G1 E100 via your printer control software.

Mark your filament again at the top of your idler arm or PTFE tubing

Eject your filament.

With a ruler or calipers, measure the distance between the two marks on your filament.

If the distance wasn't exactly 100mm, use a proportion to calculate a more precise E-steps-per-mm value.

Enter that new value into your firmware or EEPROM as you did before.

In the configuration.h file, find the Thermal Settings section. Below the comments you'll find the settings for the types of thermistors your printer uses. (Typically there will be one per hotend and one more if you have a heated bed.)

If you're installing your V6 as your only hotend, change the first highlighted line to: #define TEMP_SENSOR_0 5

If you're replacing an existing hotend or have multiple hotends, adjust whichever line corresponds to the tool number that you're changing (they start counting from 0)

Set that as your maximum temperature by changing the first highlighted line to: #define HEATER_0_MAXTEMP 285 (or adjust the line corresponding to the hotend you're changing.)

For safety it is strongly recommended to make sure that your printer detects if the thermistor stops sending correct temperatures for any reason.

Set the first highlighted line to: #define HEATER_0_MINTEMP 5 (or adjust the line corresponding to the hotend you're changing.)

In newer versions of Marlin there are other features such as Thermal Runaway Protection that might be useful as well, though they are typically on by default.
