This is a cooling frame for BigTreeTech Manta M8P 2.0 Boards. It comes in several variants and works in Voron inverted electronics compartments.
There is “Regular Size” for most stepper drivers regardless of type or brand. And “Oversized” for driver boards that extend beyond the regular footprint like Fysetc QHV5160 for example. Either variant also has variations with cutouts for connecting either 2 or 4 external driver boards for those who use them.
Pick a variant from the matching folder, and also a bottom piece according to how many driver slots you have filled on your mainboard. The bottom piece needs to be glued to the frame before assembly. See picture 5! If you fill all 8 slots you dont need any bottom piece. Also grab everything from the DIN Mount folder.
BOM:
- 2x 4010 axial fans for Raspi and the MCU cooling
- 1x 5015 radial fan for stepper driver cooling
- 10x M3x4 standard Voron heatset inserts - These go directly into the fans
- 10x M3x6 - M3x12 BHCS screws for mounting the fans
- 4x M2.5x4 Heatset inserts - These go into the DIN clips
- 4x M2.5x18 - M2.5x20 BHCS or SHCS - These mount the frame & board to the DIN clips
- For TMC5160 users: 9x9x12 Heatsinks - Double the amount of your drivers
PSA: For TMC5160 driver boards like BTT 5160 Pro or Fysetc QHV5160: Do not use the included heatsinks with this frame, as their orientation will mostly just block the airflow in the channel and result in noise and bad performance! Youll need double the amount of your driver boards in 9x9x12 heatsinks and mount them inline with the airflow path, or alternatively just print another frame with top down blowing axial fans instead. See pictures 6-7 for illustration.
Edit: I am temporarily taking the oversized frame offline for having some thermal issues with it. If it can be fixed Ill update the model. Regular size is unaffected, printed for about 100 hours at 1.2 run_current just fine.
Print with standard Voron settings, but turn on shrinkage compensation. This is modeled to real-world dimensions and not toleranced for any specific filament, so without compensation it will not fit!
