Titan Aqua Repetier 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 0 to 1, or vice versa: EXT0_INVERSE

If you're using the online configuration tool, navigate to the Tools tab and toggle the box labelled Invert Motor Direction.

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

With Repetier Host:

Connect to your printer and go to Config → Firmware EEPROM Configuration and edit the E-steps setting. Make sure to save afterwards.

Over USB Connection without Repetier Host:

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

In the Online Configuration tool:

In the Tools tab, scroll down to Extruder and update the Resolution number. If you have EEPROM, go to the General tab and switch the EEPROM usage to a different EEPROM Set to overwrite your printer's 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: #define EXT0_STEPS_PER_MM <your number here>. 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.

Manual Editing:

In the configuration.h file, find the highlighted line and update it to: #define EXT0_TEMPSENSOR_TYPE 8.

If you are installing multiple hotends, or installing this Lite6 as a second hotend, adjust the setting for the proper extruder instead (EXT1, EXT2, etc).

Online Tool:

Navigate to the Tools tab, and scroll down to the Extruder Section.

Select ATC Semitec 104-GT2 from the list of temperature sensors.

Manual editing:

Change: #define MIN_DEFECT_TEMPERATURE 5 To detect a detached thermistor

Change: #define MAXTEMP 285 To prevents your hotend from overheating.

Change: #define MAX_DEFECT_TEMPERATURE 290 To shut off your printer if overheated.

Online Editing:

Change: Maximum extruder temperature 285 to prevent your HotEnd from overheating.

Change: Minimum defect temperature 5 To detect if thermistor is detached.

Change: Maximum defect temperature 290 To shut off your printer if overheated.
