Revo Six RepRap Firmware Guide

With your Revo Six assembled and installed, next you need to configure your RepRap firmware.

We need to make sure the following are set correctly:

- Heater/Thermistor Parameters

- Maximum Temperature

First, you will need a copy of RepRap Firmware. You can simply edit your existing firmware or you can use the online configuration tool to create a new version.

You should only need to use the configuration tool if you do not have a working firmware of your own.

These values are the same as for V6 with a standard thermistor and heater cartridge.

Heater and Thermistor Values

To check what version of firmware you are using, go to Settings > General in the left hand menu of the Duet Web Interface.

Go to System > config.g :

For firmware versions 1.16 and earlier, replace the existing M305 command in the config.g file with: 

M305 P1 B4388

For firmware versions 1.17 and later but lower than 3.0, replace it with the following command instead: 

M305 P1 B4725 C7.060000e-8

For firmware versions 3.0 and later, it is slightly more complex:

You need to add the following into your existing M308 command:

T100000 B4725 C7.060000e-8

(Update the existing values and add on any missing parameters)

If you started with:                                                                                                                                  M308 S1 P"e0temp" Y"thermistor" T100000 B4092                                                                            You should alter it to:                                                                                                                                  M308 S1 P"e0temp" Y"thermistor" T100000 B4725 C7.060000e-8

Remember to PID tune your heater after altering these firmware values or it may result in a heater fault.

If using the configuration tool:

Click on the Calculate Thermistor Coefficients button in the Heaters section, and select:

Semitec 104-GT2 (used by E3D) 

from the drop-down menu.

 

Maximum Temperature

In config.g:

Locate the Heaters section and ensure the temperature limit is set to 300 degrees.

Make sure you change the temperature limit of your HotEnd and not your heated bed.

If using the configuration tool:

Update your maximum temperature by going to the heaters tab and ensuring the option is set to:

300

Remember to restart your printer for your new values to come into effect.

You should PID tune your heater after altering these firmware values or it may result in a heater fault.
