        <title>2 PWM fand from single output?</title>
        <description> Hi,

My hotend has 2 part cooling fand. They naturally have to work simultaneously. Is it advisable to use a single PWM output on the board for this purposr or should I use a single output by splitting the wire? Also, if splitting is an option, is there a tool/crimp/etc to split a wirein two?  I try to wrap 1 wire around the crimp of the second wire but it isn’t very solid of course and can be dislocated. If I use solder to attach the wire to the crimp, it doesn’t fit into the plastic connector housing.

Thanks.</description>

            <description><![CDATA[ Hi there,<br />
i have the same Question, but in my scenario, it dosent work to connect two Fans on one output. (the Board burn)<br />
My question now is how to define it to use two outputs sync.<br />
<br />
Unfortunately, these three attempts did not work in the Pin Config.<br />
<br />
#define FAN_PIN PC8 &amp; PE5 <br />
<br />
#define FAN_PIN PC8 and PE5<br />
<br />
#define FAN_PIN PC8 + PE5  <br />
<br />
<br />
(I have the SKR Pro V1.1 board)<br />
<br />
Greetings, Marta]]></description>
