Just finished my swap. Was pretty easy and the print quality is marginally better. It isn't night and day, but noticeable. I will have to try it on some trickier prints and report back.
What at I do notice is a more even draw on my power supply. Before, whenever the bed relay kicked in the lights that I have mounted would flicker. Almost to the point it seemed like they were turning completey on and off.
Now, they Slightly flicker but the voltage is much more constant. Before the swap, the voltage would cruise at 12.2 and then drop almost to 10 as soon as the relay kicked in. I had to turn it up to 13 just to keep the voltage above 11 when heating. I was able to back down the voltage at idle to 12.3 and it never drops below 12 now.
Here is a video of the current flicker. You have to look at the wall to see it. It kinda matches the pulsing of the communications led on the rumba. I'm looking for a vid of the previous flicker. Think strobe light!
