First things first: you're going to need a copy of Repetier.
-
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 Repetier, download it at https://www.repetier.com/download-now/
-
-
-
Almost all printers use Arduino IDE to upload fresh firmware, so download it at https://www.arduino.cc/en/Main/Software
-
-
-
Unzip Repetier from the zip file you downloaded and put the resulting folder anywhere on your computer for safe keeping.
-
Inside this folder, navigate to the Repetier sub-folder, and open the
Repetier.ino
file. This should open every file in Marlin. -
Find the
Configuration.h
file
-
-
-
If your old extruder was ungeared, you'll notice that your new Titan extrudes backwards!
-
Flip the folowing line in the
Configuration.h
file from0
to1
, or vice versa:EXT0_INVERSE
-
If you're using the online configuration tool, navigate to the
Tools
tab and toggle the box labelledInvert 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, sendM500
to store your settings -
In the Online Configuration tool:
-
In the
Tools
tab, scroll down toExtruder
and update theResolution
number. If you have EEPROM, go to theGeneral
tab and switch theEEPROM 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
, 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.
-
-
-
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.
-
-
-
Upload the new firmware to your electronics as you normally would. Typically this means plugging in your printer to your computer, selecting the correct COM port and board type, and pressing the upload button.
-
If you're unsure of how to update your printer's firmware, check with its manufacturer.
-
You're all done. Enjoy your new Titan!
