About the LGX PCB
LGX is an open source PCB design by MaximeLambrechts, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 45.5 × 32 mm, with 9 components from 9 distinct parts.
By type, the board carries 8 connectors and 1 diode.
From the project
A PCB design for Voron Stealthburner & Bondtech LGX
This mod is a custom 2-piece PCB design, as well as a few printed parts, to make the Bondtech LGX fully compatible with the Voron Stealthburner.
This mod is based on two existing mods, all credits go to them for the initial design :
LGX Stealthburner Mount Remix by Symataris on Thingiverse (link here) Stealthburner toolhead PCB by Hartk1213 (link here)
I really like the 2-piece PCB design by Hartk, with which you just plug the stealthburner in the main board via a connector, without having to deal with cables from the fans and LEDs.
