TD:LR - Upgraded my ender 3 over a couple of years, Bed leveling probe, direct drive, Klipper and SKR3 board upgrade. (SO MUCH QUITER)

Ive got an ender 3 which i've had since 2019 and I have been on and off using it, its moved house and will be honestly at some times been extremely neglected at some times but it has just kept on powering through.

  
Ive now upgraded to the SKR3 with TM2209 drivers for Dual Z axis - Mostly for fun cause i love to tinker. So far from playing around with these new drivers the noise level difference is CRAZY, its practically silent now when fans are not running.

History:  
Got the Ender 3 brand new, i knew nothing about 3d printers, CAD. Didnt even have a need for it just though it was cool.

I remember trying to print one of the sample files on the SD card using the sample filaments thinking that they would provide enough to complete the sample file they provided...

  
First upgrade: within a year or so.

The first upgrade i did to this printer was installing the EZABL sensor with Marlin - My god from what i remember trying to compile the firmware for the first time, i wanted to throw it across the room. Used an Arduino to upload the code as there was no boot loader on the board. First layers were amazing once setup

  
Second upgrade: roughly a year ago.

I upgrade the hot end  as i started printing with ASA and with the ender 3 hot end it wasnt full metal it had the tube which starts producing nasty fumes above 240\~ ish which i was printing at 250 running in my garage with the door cracked (In carboard enclosures)  
So i put in the Sprite Pro extruder as it was meant to be a direct upgrade for the most part.  
and i wanted to start playing around with other filaments such as TPU.

  
Third Upgrade: roughly a year ago.

Klipper!! After looking into 3d printing communities i heard about Klipper and started to see what it is about. So for probably around a 2 or so weeks, i painstakingly went through setting up klipper on the original ender 3 board to which i finally got working with hit and miss results on some prints (Mostly around the first layer, i always seem to need to adjust the baby steps ) was happy to just deal with it.

  
Fourth Upgrade: Today

SKR3 V3 - OMG ITS SO QUIET (I run my printer in my room and mostly overnight), i thought people might of been exaggerating how much quieter. I went through and had set up the printer config and the drivers, currently just going through all calibrations which ive only ran 2 regarding first layer and making it consistent 

I also added a second Z axis thinking it would make all my prints / bed meshes even better, so far been quite fiddly due to Z axis drift. I havent helped my self the Z axis kit has a new motor, lead screw and ive got the old one still on the other side. I also believe it has to do with the frame as well, will try and resquare but i need to sleep...

Thank you for listening to my rant!!

All advice is welcome and more than wanted!
