This guide assumes you have a printer already running RepRapFirmware. It will talk through the steps for adjusting the firmware settings for the Titan Extruder.
-
If you do not yet have RepRapFirmware installed on your Duet then see the Duet3d wiki: https://duet3d.com/wiki/Duet_Wiki
-
You can edit your existing firmware either through the online configuration tool, or through DuetWebControl
-
-
-
Flip the corresponding line in your
config.g
file fromS1
toS0
or vice versa:M569
-
You can also simply send the
M569
command through your favourite printer control software or through Duet Web Control
-
-
-
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 or Duet Web Control
-
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
.
-
-
-
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.
-
-
-
Once you have established the correct steps per mm then update config.g with the correct number (M92 <correct E steps> )
-
If you're having issues, check with your printer's manufacturer.
