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

    • If you are upgrading an existing 3D printer to use a Titan, you should try to get a copy of your current firmware from your printer's manufacturer.

    • If you're building a new printer, or simply want to upgrade to the latest version of Marlin, download it at http://smoothieware.org/getting-smoothie

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

    Edit

    • Unzip Smoothieware from the zip file you downloaded and put the resulting folder anywhere on your computer for safe keeping.

    • You will be working with the config file. This file along with the firmware will eventually need to be stored on the microSD card you insert in to your Smoothieboard.

    • If unfamiliar with how to configure your Smoothieboard, refer to the Smoothieware documentation.

    Edit

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

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

    • Add or remove a ! from the number after the following line: extruder.hotend.dir_pin.

    Edit

  5. 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

  6. 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 file manually:

    • Update the following line with your new number: extruder.hotend.steps_per_mm. Upload your firmware as normal.

    Edit

  7. 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

  8. 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.

    • 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.

    • Repeat iteratively. Average the values you measure to reduce error. Extruding further (such as 150mm) may be helpful for reducing error (presuming you measure your filament while it's totally straight against your calliper/measuring device

    Edit

    • Save the revised Smoothieware config file to your SD card as you normally would. If you're having issues, check with your printer's vendor/manufacturer.

    • If you're unsure of how to update your Smoothieware config, check with your machine's vendor/manufacturer, or refer to the general Smoothieware documentation

    Edit
Conclusion

You're all done. Enjoy your new Titan!

Thanks Gabe. I made a few tweaks that I think help a little, but overall this doc is good as-is. Props for writing it!
