ABL or auto bed levelling is a must for many Ender 3 owners because their beds have arrived warped. ABL will probe the print surface before each print and build a virtual mesh which alters the early layers to match the contours of the bed. The result should be a much better first layer and hopefully a better and more reliable print.

This is part 1 of a head to head ABL shootout, with part 2 featuring the BLtouch. The EZABL from this video was supplied by Tim from TH3D to make this guide, and is the direct connect version. I chose it because I didn’t want to use another power point for the EZABL. The EZconnect version is simpler to install than what I’ve shown here. You could get an XT60 splitter to take your power from there instead of touching the mainboard.

This video assumes you have flashed a bootloader with my previous guide:    • Ender 3: How to install a bootloader ...  

This install retains full SD card support for offline printing.

UPDATE: To making setting Z offset easier I would recommend enabling babystep offset by uncommenting:
#define BABYSTEP_OFFSET
After you set it at the start of a print, simply store the settings in the EEPROM.

If you are getting this kit, make sure you buy directly from TH3D, not another vendor who is trying to rip them off.
