Do you have a slicer profile? Originally I was using https://github.com/DrLex0/FFCP-GCodeSnippets with the original firmware and PrusaSlicer, but after struggles with dual extruders, I converted to Klipper using your guide. Great guide by the way.
I am not sure how to convert the profile for Klipper.

Glad the guide helped you!

Here are the settings I used in Cura to create a printer profile for this conversion (stored in Flashforge+Creator+Pro_settings.inst.cfg in the definition_changes folder of the config directory.

Klipper handles the nozzle offsets internally, so it seems like all you need is for your slicer to generate the T1 / T2 toolchange codes correctly.

[general]
version = 4
name = Flashforge Creator Pro_settings
definition = custom

[metadata]
type = definition_changes
setting_version = 23

[values]
extruders_enabled_count = 2
machine_center_is_zero = True
machine_depth = 148
machine_end_gcode = END_PRINT
machine_extruder_count = 2
machine_head_with_fans_polygon = [[-20, 10], [-20, 10], [10, -10], [-20, -10]]
machine_heated_bed = True
machine_height = 150
machine_start_gcode = START_PRINT BED_TEMP={material_bed_temperature_layer_0} EXTRUDER_TEMP={material_print_temperature_layer_0}
machine_width = 227

Alternatively you can just copy the info from these screenshots if that's easier:

I have done as the tutorial advises and have one small issue:
After I copy/paste your 'printer.cfg' I get from mainsail:

**Klipper reports: ERROR

Option 'position_endstop' in section 'stepper_z' must be specified

Once the underlying issue is corrected, use the "RESTART"
command to reload the config and restart the host software.
Printer is halted**

I changed

#position_endstop: -0.25
to
position_endstop: 0.25

I got the following error:
Option 'scl_pin' is not valid in section 'mcp4018 x_axis_pot'

I corrected it by changing the names to the new name:

[mcp4018 x_axis_pot]
i2c_software_scl_pin: PJ5
i2c_software_sda_pin: PF3
wiper: 118
scale: 127

[mcp4018 y_axis_pot]

i2c_software_sda_pin: PF7
wiper: 118
scale: 127

[mcp4018 z_axis_pot]
i2c_software_scl_pin: PJ5
i2c_software_sda_pin: PK3
wiper: 40
scale: 127

[mcp4018 a_axis_pot]
i2c_software_scl_pin: PJ5
i2c_software_sda_pin: PA5
wiper: 118
scale: 127

[mcp4018 b_axis_pot]
i2c_software_scl_pin: PJ5
i2c_software_sda_pin: PJ6
wiper: 118
scale: 127

I got the following error: Option 'scl_pin' is not valid in section 'mcp4018 x_axis_pot'

Ah, good note. Looks like the name of the configuration option was changed at the end of 2025.

20250721: The [pca9632] and [mcp4018] modules no longer accept the scl_pin and sda_pin options. Use i2c_software_scl_pin and i2c_software_sda_pin instead.

I'll update the gist, thank you!
