    • First things first: you're going to need a copy of RepRap Firmware.

    • Either download a fresh version from GitHub, or edit your existing one.

    • You can edit your existing firmware either through the online configuration tool, or through G-Code.

    • If you download a fresh version of RepRap Firmware you'll have to configure more settings than the ones mentioned in this guide so that it will work well with your printer.

    Edit

  2. Flip the corresponding line in your config.g file from S1 to S0 or vice versa: M569

    • Flip the corresponding line in your config.g file from S1 to S0 or vice versa: M569

    • You can also simply send the M569 command through your favourite printer control software.

    Edit

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

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

    • Your slicer will generate G-Code for your printer, which will tell it to extrude a certain length (in millimeters) of filament. Your printer takes those lengths of filament and calculates how much it should rotate your Titan's stepper motor to push out the expected amount filament. This number is used to make that conversion

    • 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

    Edit

  4. Over USB Connection

    • 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

    • Update your config.g file manually:

    • Update the following line with your new number: M92.

    Edit

  6. To get a more exact value for your E-steps-per-mm, measure the exact amount of filament that is pushed out of your extruder. 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 .

    • 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.

    • You may need to heat your HotEnd before your printer allows you to extrude filament. You can use M302 command to get around that.

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

    • Eject your filament.

    Edit

  7. 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.

  8. Manual Editing: For firmware versions 1.16 and earlier, send the folowing G-Code command to your printer: M305 P1 B4388

    • Manual Editing:

    • For firmware versions 1.16 and earlier, send the folowing G-Code command to your printer: M305 P1 B4388

    • For firmware versions 1.17 and later, send the following command instead: M305 P1 B4725 C7.060000e-8

    • Online Tool:

    • Click on the Calculate Thermistor Coefficients button in the Heaters tab, and select Semitec 104-GT2 (used by E3D) from the drop-down menu.

    Edit

    • Update, For the most recent version of the reap rap firmware you should be using the following parameters for the thermistors.

    • T parameter: 100 000

    • B parameter: 4725

    • C parameter: 7.06e-8

    Edit

  10. Manual editing:

    • Manual editing:

    • Update your maximum temperature by sending the following G-Code command to your printer: M143 S285

    • While the Titan Aero's metal componants can handle very high temperatures, the included thermistor cartridge will strugle with temperatures over 285°C (if you want to go higher, get a PT100).

    • Online Editing:

    • Update your maximum temperature by going to the heaters tab and changing the option to 285.

    Edit

    • Save the firmware to your SD card as you normally would. If you're having issues, check with your printer's manufacturer.

    • If you're unsure of how to update your printer's firmware, check with its manufacturer.

    Edit
Conclusion

You're all done. Enjoy your new Titan!
