BTT EBB42 (customised and customizable) box for TronXY X5SA Pro using stock gantry mount

box for BTT EBB42 CAN v1.2 board forTronxy XY X5SA Pro printer

I upgraded my X5SA Pro to Klipper and got rid of the cable nonsense from Tronxy by using CAN, in the case the BigTreeTech/BTT/Biqu EBB42 CAN v1.2 board. This is mounted to the original gantry plate of the stock X5SA Pro printer.

This box mounts on the back of this original gantry plate instead of the original cable chain of the stock printer; this cable chain is not used any more (CAN bus used instead) and the 2 mounting holes are available. Beware: these mounting holes are threaded - forM3.5 screws! (not M3 as all the rest on the printer!) - be sure to retain the original screws, M3.5 is rather hard to come by - or use M3 and counter nuts.

Several different mounting options are provided, depending on your use case and preferences; e.g. the type of toolhead used (I use Hero Me Gen 7.4).

The PCB is mounted on raised columns, use M3 5.7 heat inserts for that. The lid is fixed with 4 screws, as well use M3 heat inserts for that (holes for the lid are 15 mm deep, so basically any M3 screw will do).

I did attach three cable management towers for the cables coming from the toolhead (heater cartridge, thermistor, ABL sensor, fans, ...).

Print Settings

Rafts:

No

Supports: 

Yes

Resolution: 

0.16 - 0.28

Infill: 

25 - 45%

Filament Material: 

PETG

Notes: 

I printed this in ABS (Geeetech ABS+), just because the spool was already loaded for all the other HeroMe parts. Should work in PLA, PETG, ASA, ... as well, there is not much mechanical strain on the box.

For all my printer accessory parts, I use

• out layer height: 0.14mm
• inner layer height (inner perimeters and infill). 0.28mm
• line width 0.6mm
• 45% infill (not really needed here though)
• adaptive cubic infill
• automatic tree support with lean trees, on buildplate only, "only critical" NOT checked

and two postprocessing scripts in OrcaSlicer 2.3.0

• https://github.com/TengerTechnologies/Smoothificator
• https://github.com/TengerTechnologies/Bricklayers in this version https://github.com/TengerTechnologies/Bricklayers/blob/main/NonPlanarInterlockingWalls.py
• settings see file "orca-settings.txt"

The .3MF is for OrcaSlicer 2.3.0, the _generic.3mf is exported from OrcaSlicer als "Generic 3MF", whatever that means.

STLs are exported from OrcaSlicer. Go for the 3MF if possible.

How I Designed This

OpenSCAD (2025 version)

I used the OpenSCAD script listed as "Remix sources" and changed the fonts used for the text (last paragraph in script), on Linux. You have to change those fonts to something thad is available on your computer and use OpenSCAD locally.

If you don't like the texts, you have to use OpenSCAD locally installed, the Thingiverse customizer will NOT work.
