I've added support for the ZM384 here. Due to some quirks with Klipper, as of now, only three extruders will work with the 3MS, and the fourth one will be used as the main extruder.

EDIT:

I have added experimental support for replacing the printer's extruder with the 3MS, allowing (in your case), for four colors.

In macros.cfg:

# Set the sync of provided TOOL to SYNC with extruder
### --- Comment if using the 3MS instead of your printer's extruder --- ###
[gcode_macro SET_TOOL_SYNC]
gcode:
  {% set tool = params.TOOL|int %}
  {% set sync = params.SYNC|int %}
  {% set motion_queue = "extruder" if sync == 1 else "" %}
  SYNC_EXTRUDER_MOTION EXTRUDER=3ms{ tool } MOTION_QUEUE={ motion_queue }
### --- Comment if using the 3MS instead of your printer's extruder --- ###
# [gcode_macro SET_TOOL_SYNC]
# gcode:
#   {% set tool = params.TOOL|int %}
#   {% set sync = params.SYNC|int %}
#   {% set ext_name = "3ms"+(tool|str) %}
#   {% if tool == 0 %}
#     {% set ext_name = "extruder" %}
#   {% endif %}
#   {% set motion_queue = "extruder" if sync == 1 else "" %}
#   SYNC_EXTRUDER_MOTION EXTRUDER={ext_name} MOTION_QUEUE={ motion_queue }

Wow that was fast :) Thank you. I have ordered some parts for my machine and will be reworking it.

I plan on using the bambulabs splitter and attach to the hotend.

is the ok?

[3DCoded]

That splitter looks good, but you can also print this one.

[3DCoded]

The spitter I previously linked is no longer recommended for setups with more than two filament units (you would need three of those splitters). For a system like yours, this one is now recommended (you only need one of these splitters).

[kaiatkins]

The ZoneStar Z9v5 printer has 4 BMG extruders on the back and feeds either into the company's 4 in 1 out (mixing hotend) or 4 in 1 out (non- mixing hotend) but they lack in quality. So I have switched to klipper and wanted the option to change the hotend into a Bowden single E3D v6 then use like the bambulabs AMS splitter.

[3DCoded]

The 3MS will work fine on an E3D v6 hotend. I recommend getting the splitter as close to the hotend as possible for the speed of tool changes.

[kaiatkins]

Where would be the optimal location for the filament sensor? Currently its the red on the back of the machine before the extruder.

[3DCoded]

The optimal location for the filament sensor is between the splitter and the hotend.

I picked up (SFS 2.0) on sale that I will use. Once everything arrives, I will start :) thank you for your quick responses, guidance and support 👍

Here is what I had in mind it would be setup as
