Raytools BT240S Consumables: D32 M14 Nozzle and the Bullet Option
BT240S is a 2D head on the D32 family — not a tube head
There is a persistent mix-up about the Raytools BT range: because some BT heads sit on 3D machines, BT gets filed as “3D / tube”. The parts tables do not support that. The BT240S appears on the D32-H12-M14 ceramic ring, alongside the BM109 / BM110 / BM111 / BM114S — a 2D family.
That single fact decides the order: a 3D body (D15 / M8) will not seat on a BT240S, and a D32 M14 nozzle will not thread onto a tube head.
Parts that follow a BT240S
| Part | What fits | What decides it |
|---|---|---|
| Ceramic ring | D32-M14 (D32-H12-M14) | Ring diameter and M14 thread |
| Standard nozzle | D32 body, 15 mm tall, M14, single and double layer | Bore, layer type, coating |
| Bullet / E-type nozzle | Slim 10.5 × 22 mm tip, held by a separate locking nut | Bullet nozzles have their own numbering; send the old one |
| Protective window | Drawer-format window on the BT range — measure the old one (D × T) | Diameter, thickness, power rating |
| Focus lens | D30 family, focal length to match the module | Marking on the module |
We list the bullet nozzle separately on purpose: it is a different clamping system (locking nut, not thread into the ring), and buying “a D32 nozzle” when the head is set up for bullets is a guaranteed mismatch.
Where BT240S orders go wrong
- Filing BT as 3D. BT240S is a 2D head with a D32 M14 ring. The 3D parts belong to the TC-type heads.
- Forgetting the bullet set-up. A head running bullet nozzles has a locking nut and a different seat; a standard D32 nozzle is not a drop-in replacement.
- Assuming BT240 parts fit BT240S. Same family, but check the ring and the nozzle seat — the S is a different revision.
How to confirm
- Nameplate photo — BT240S vs BT240 vs BT220.
- Photo of the nozzle in place, showing whether it is a threaded D32 or a bullet held by a nut.
- Old window out of the drawer, measured.
- We confirm ring, nozzle type and window size in one reply.
FAQ
Do BM110 nozzles fit a BT240S?
Yes — both are D32 H15 M14 on the same D32-M14 ring. The bore and layer type still have to match your process.
Can I use D28 M11 nozzles instead?
No. D28 / M11 belongs to the BT220 / BM114 / BM115 / BS series. On a BT240S the thread is M14 and the body is 32 mm.
Is the BT240S the same as the BT240?
Same family, different revision. Ring and nozzle seat should be checked on the machine rather than assumed from the name.
