I took a video of my printer not working . I am having some serious difficulties with my controllers. I do not think that the board is blown, I do not see how ONE port could blow. I do not think that it is the stepper driver, I juggle MULTIPLE ones into that port to no avail. I do not think that it is the feed rate I have had success changing that several times, Ieven changed the max speed, it had an effect which was not the one I was looking for. The unit actually moved less. . THE problem came after I printed a Terminator Rex, and the next print the extruder seemed a little lazy. I stopped the print, went to see if I have any clogs or problems and now I have this. This problem persists after reprogramming, after changing motors, after changing out the jumpers. Any help would be greatly appreciated.

First issue: never ever plug in or unplug steppers while it is on! this will kill the driver 95% of the time.

Second problem: You haven’t actually said what your problem is... Slow E im guessing

The reason your E is running so slow is you have changed the extruder speed in pronterface to 5mm/minute (the box next to the the length you want to extrude)
This should be more like 250. So it is literally taking 1 minute to move 5mm.

The screen clearly shows this at 1:06 seconds.

But this only effects manual extrudes. But definitely change it for testing.

Also one IO port on the mega dying is very common. but if it moves. it not that
