Product description

These original BL-Touch upgrades fit many 3D printers. A flat bed is one of the most critical things for a successful 3D print, an uneven bed can cause issues with the first layers not siting on the bed correctly. There is also the issue of the bed becoming slightly out of line after a long or large print. Once installed and set up your 3D printers can allow and adjust for the slight variances to ensure optimum printing conditions and reduce failure rates from a slightly off bed level.

Installation varies between printers, however the general principle is similar enough. Firstly mount the BL-Touch unit to your printer (you may need to print a mount). Secondly hook up the connections (a lot of printers have a BL-Touch connector on the extruder assembly, some older ones may require wiring to the mainboard. Finally activate the 'Auto Level' feature in a menu or through updating the firmware.
