Formbot3D Xplorer Manta M8P V2 Fan Mount

UPDATE 1: I've created a skirt mod to accommodate the bigger fan if you plan on installing the electronics cabinet cover. Check it out here on printables. 

I love this cooler for my Voron, but it wouldn't work with the Xplorer as it is flush mounted to the skirt. So I improvised and flipped 5015 blower to the other side. While it is facing down, the Manta is mounted pretty high from the bottom on risers so it has plenty of room to pull air. It's also the best option concerning cooling of the stepper sticks in my opinion. 

Lastly, this is modeled to make use of 4010 fans. Most screws and installation steps are largely the same from the parent model. 

Finally, I'm a hack cad modeler. I've included the step with hopes that if this can be improved, someone with more skill than myself has a better time. I used plasticity but had to use freecad to convert it to a solid first since the original model is a mesh. I learned a lot, but this is as good as it gets for this model from me.

Installation Instructions for Xplorer
================================================================================
Needs 2 24v 4010 fans, 1 24v 5015 blower, and a 3 to 1 fan combiner. You could easily splice the 4010's together and pig tail a 2 pin jst xh connect to plug into the manta, but combiners are cleaner and allow for easier replacement in the event of a failure. 

Step 1: Make sure the jumper for FAN1 and FAN2 are set to 24v. 

Step 2: Next, Plug the 5015 fan into FAN1 and the combined 4010 fans into FAN2. See the reference image with port assignments of the manta m8p v2 here

Step 3: In mainsail, navigate to machine from the left side navigation to get to the configuration files. 

Step 4: Navigate to /config/01__User_Custom__CFG and create a new file named cooler.cfg and press create. Paste in the following configuration file: 

[controller_fan stepper_fan]
pin:PF9
cycle_time: 0.1                  # Cycle time
max_power: 1.0                   # Maximum power
shutdown_speed: 0.0              # Shutdown speed
fan_speed: 1.0                   # Fan speed when heater or stepper driver is active (0.0 to 1.0). Default is 1.0.
idle_timeout: 90                 # Time in seconds to keep the fan running after the stepper driver or heater is no longer active. Default is 30 seconds.
idle_speed: 1.0                  # Fan speed after the stepper driver is no longer active and before idle_timeout is reached (0.0 to 1.0). Default is fan_speed.
stepper: stepper y, stepper y1, stepper y2, stepper y3, stepper x, stepper x1, stepper x2, stepper x3

[temperature_fan mcu_fan]
pin: PF6
control: pid
target_temp: 50
max_power: 1.0
min_temp: 0
max_temp: 85
off_below: 0.2
kick_start_time: 0.5
sensor_type:temperature_host
pid_Kp: 5.0
pid_Ki: 0.20
pid_Kd: 50.0

Step 5: Navigate back to the /config folder and open up the printer.cfg file. We need to include our new configuration file into the user mods section. The user mod section starts with this: 

#### --> User custom CFGs <--################ ############### --> Added by the user <-- ### 

Paste an entry for your new configuration file in below that header: 

[include ./01__User_Custom__CFG/cooler.cfg] 

Click the save and restart button 

Step 6: Verify your new MCU fan is working by looking at the temps on the dashboard. You should see a new fan named Mcu fan. I've found that it will stabilize and just run constantly at 30% and it'll stay there pretty happily. It does a great job cooling the soc and mcu! 

Step 7: Verify your new stepper fan is working by homing the printer. Home all is good. You should hear the new fan spin up as soon as the steppers start up! You can also verify that fan is configured without homing by scrolling down on the mainsail dashboard to the Miscellaneous section and look for Stepper Fan. This fan isn't controllable as it has conditions that start and stop it. But you should see it. Once you home the printer, you should see it's state reflected at 100%. 

Step 8: Enjoy better, targeted cooling! (edited)Saturday, November 15, 2025 at 2:41 PM
