Hey Alex,

thank you for putting this into the feature requests.

It is worth noting in this context that there exist variants of these cnc-suitable milling motors that offer a **lever-activated, tool-less quick tool change option** , like the [Mafell FM 1000 PV-WS](https://produkte.mafell.de/en/mortising/milling-motor/milling-motor-fm-1000-pv-ws)

 ![fm1000_ws_zoomFUmxHSDuDUPWm_600x600__cropped](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/c/c/cc88195be2452302dd73687b8cdbd29d035991fc.png)  
[Mafell Milling motor FM 1000 PV-WS](https://produkte.mafell.de/en/mortising/milling-motor/milling-motor-fm-1000-pv-ws)

or the [tool changer models from AMB ELEKTRIK](https://www.amb-elektrik.de/en/products/milling-motors-with-tool-change-systems/):.

 ![FMEUDI-06083004_rotated](https://us1.discourse-cdn.com/flex022/uploads/onefinitycnc/original/3X/a/6/a696475c7a7a5f2fd1fdd814294bded5b18ac5fb.png)  
[AMB Milling Motor 1050 FME-U DI 230V (for ER16 precision collets)](https://www.amb-elektrik.de/en/products/milling-motors-with-tool-change-systems/636/amb-milling-motor-1050-fme-u-di-230v-for-er16-precision-collets?c=94)

(besides these manual quick tool changers models, AMB also offers a variant with _automatic pneumatic_ tool change.)

I am very confident that hobbyists and semiprofessionals that own or plan to buy a Onefinity CNC machine would not only be interested in being able to [use the cnc-suitable milling motors with 43 mm “Euro” mount](https://forum.onefinitycnc.com/t/introducing-the-new-onefinity-elite-series-powered-by-masso/16706/115#best-milling-motor-solution-for-hobbyists-and-semiprofessionals-1), but also the quick tool change variants¹.

These milling motors variants with quick tool changer do **not** fit into a 43 mm diameter motor mount, but expect a **flat spindle mount plate** like the [universal Z assemblies](https://forum.onefinitycnc.com/t/universal-z-axis-assembly/4415) found on the Z-axis of most CNC machines:

Therefore I think if Onefinity would consider an option for 43 mm “Euro” mount milling motors, if they made a solution similar to this one, it would allow to have a flat mount plate anyway:

#### Footnotes

1.) [Suhner](https://forum.onefinitycnc.com/t/machinist-in-x-50/8159/18) also offers a [pneumatic automatic tool changer with SK-15 tool holders](https://www.sorotec.de/shop/Tool-Changer-for-Suhner-1050-UAD-25RF-V02-and-UAK-30RF-1530W.html), but this one fits 43 mm diameter mounts
