About This Kit


Arguably the best upgrade for a 3D printer, Auto Bed Leveling is here to stay. Especially for the Anet A8. Twiddling the small and hard to reach wing nuts to level your bed is one of the biggest annoyances of the Anet A8 and many other printers for that matter.

Uptanium has released this ABL kit that utilizes a capacitive Z-Probe sensor so you can choose any build surface you want. Capacitive sensors work on Glass, aluminium, BuildTak, and more.One of the best and most recommended is Glass. The Uptanium ABL kit uses bi-linear auto bed leveling and will sense multiple positions on the build surface and extrapolate, or guess what angle, the rest of the bed is outside of each probe point. Glass is probably the straightest material and is easier for ABL to construct a very accurate level surface.

The uptanium Auto Bed Leveling kit also utilizes an optocoupler to electrically isolate the capacitive sensor. Why you ask? Since the capacitive sensor uses the variation in capacitance of itself and the build surface, any electrical noise generated from the 3D printers power supply could interfere and result in unreliable sensor readings. To get the best repeatability and most accurate bed leveling, an optocoupler is a must have for a capacitive sensor.

So how accurate is the Uptanium ABL kit? For the average on a test of 50 probes, the standard deviation is 0.039 +-0.004. For perspective, that is less than half of the finest layer height of .1. Or, less than 5 percent of your average .4 mm nozzle width. That's really good.

A note about Anet A8 printers. Anet has been known to ship some of the printers without a bootloader. This will prevent any firmware uploads unless you install a bootloader. If you are unsure if you have a bootloader, please see our Burn Bootloader guide or purchase our USBasp Programmer Kit. A bootloader needs to be present for this kit to work. Approximately 1 in 50 printers seem to be affected.


Compatibility List

How hard is it to install?

The only tools needed are a small flat head screw driver, 2.5mm allen wrench and a Philips head. That's it. The typical installation should take approximately 30-60 minutes following the include instructional PDF.
