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
-
-
-
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.
-
-
-
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
.
-
-
-
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
-
-
-
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.
-
-
-
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
, thenG1 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.
-
-
-
On the SD card that contains your printer's firmware, update the configuration file with the following line:
temperature_control.hotend.thermistor Semitec
-
-
-
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.
-
You're all done. Enjoy your new Titan!
