        <title>Prusa I3 - X Axis go crazy randomly mid prints.</title>
        <description> Hi there, have this build for a while now. Recently i started having this issue, during my prints, the X axis stops for a heartbeat, then goes crazy both directions, very fast.
This happens sometimes during the first layers, some other times after 1 hour of printing. What i&#039;ve tried so far:

Replaced the stepper driver for the X motor, didn&#039;t fix.
Replaced the X endstop, didn&#039;t fix.

Has anyone ever had this issue?  Any feedback will be appreciated.</description>

            <description><![CDATA[ I solved it:<br />
<br />
- The stepper driver was burning hot. I replaced all steppers, but the problem persisted. (Printing a closed cooling system for stepper drivers and mosfets).<br />
<br />
- Replaced the motor. Problem persisted. (Later on i realised motor was also damaged).<br />
<br />
- Replaced the RAMPS, problem fixed.<br />
<br />
- Motor had problems when i used it in my other printer. Tried with different drivers and it doesn't rotate.<br />
<br />
The reason for this problem to happen, i think, it might have to do with the overheating of components. I was not using any cooling over my eletronics (but truth be said, i've been using it like this for over a year). Problems started showing when i decided to heat up the bed another 10ºC (60 &gt; 70) and some firmware misconfiguration wasn't shutting down the heatbed after printing was done. So i had the headbed on (and mosfet burning) for several hours.]]></description>

            <description><![CDATA[ It might be the motor or the step sticks were hot, ever tried to touch the motor during operation? it's not recommended to touch the stepstick during operation though. <br />
<br />
If it does hot, try to reduce the stepstick current]]></description>
