Titan RepRap Firmware Configuration

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 from S1 to S0 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, then G1 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.
