LGX_Lite_Stealthburner_CW2_style_mount VS whopping_Voron_mods

The Tool Head runs an LGX Lite Extruder requiring a different Shell not compatible with the SB2209/2240 on dimensions alone ( checked it with their CAD Models ) due to the motor / extruder portion not being as offset as a CW2 and on top of that the SB2209/2240 being very particular about their positioning due to the Front Cover Daughter Board.

I don’t have a clockwork as I use LGX Lite as the extruder. I used this one https://github.com/Eytecz/LGX_Lite_Stealthburner_CW2_style_mount together with SB beta parts. I had to cut the LGX lite mount a bit to fit the ERCF PCB. To mount the PCB I used this https://github.com/VoronDesign/VoronUsers/tree/master/printer_mods/Fiction/LGX_Lite_toolhead_PCB_mount

The mounts are the Whoppingpochard design.

I built a 300, and I can see the bi-metal extrusion warping without gantry backers that seems to be the biggest concern with going larger. (https://github.com/tanaes/whopping_Voron_mods/tree/main/extrusion_backers)

Insufficient heat soaking. As the chamber warms up the frame members deflect from thermal expansion, causing the toolhead to rise. In my experience you need a good hour or so with the doors closed for temperatures to stabilize enough, on a stock build. Putting backers on the Y rail extrusions can mitigate this as well: https://github.com/tanaes/whopping_Voron_mods/tree/main/extrusion_backers
