FLSun Cube Part Cooling Fan

prusaprinters

<p>This is a part cooling fan for the FlSun. The original design has only one fan<br>that cools the extruder and the part at the same time, but it doesn't do a good<br>job.</p><p>This part cooling fan is a complement to the extruder cooling fan that can be<br>found here: <a href="https://www.thingiverse.com/thing:3994567">https://www.thingiverse.com/thing:3994567</a></p><p>You'll need these to install this part cooling fan:</p><p>o a 5015s radial fan<br>o two M4 x 20 mm screws and nuts (to replaces the existing screws)<br>o two M3 x 22 mm screws and nuts<br>o two M3 x 10 mm screws and nuts</p><p>The part cooling fan is held to the X carriage using two of the screws holding<br>the linear bearing. Nevertheless, you will need to use de M4 screws mentioned<br>above.</p><p>You will need to change the wiring to install the cooling fan. Thus, you will<br>need to reflash Marlin. It is recommended to do it also for the extruder fan.</p><p>I've connected the board fans along with the extruder fan on port D7. I<br>modified the following parameters in Configuration_adv.h:</p><h3>define E0_AUTO_FAN_PIN 7</h3><h3>define EXTRUDER_AUTO_FAN_TEMPERATURE 40</h3><p>This way, the extruder, and board fans run only if the extruder temperature is<br>above 40C, which is a big relief when it is not printing.</p><p>The part cooling fan is installed on D9. To do so, I've modified the following<br>parameters in Configuration_adv.h.</p><h3>define FANMUX0_PIN 9</h3><p>While doing it, I recommend you to make sure that THERMAL_PROTECTION_HOTENDS<br>and THERMAL_PROTECTION_BED are enabled in Configuration.h</p><p>This object main web page is:<br><a href="http://www.ctheroux.com/flsun-cube-part-cooling-fan/">http://www.ctheroux.com/flsun-cube-part-cooling-fan/</a>.</p><p>You can request the source files on the page listed above.</p>
