@Phaedrux , @droftarts
Thanks guys - my unfamiliarity with GitHub was the cause. All sorted now - body, idler and lid are all successfully imported into Fusion 360.

Hi All,
I tried to import the STEP files for the magnetic sensor into Fusion 360 and all 3 files failed. The error report says "Content of the file is corrupted or invalid". I'd like to incorporate a bespoke mounting option and would prefer to work with the STEP files rather than the STLs.
Has anyone succeeded with this? I have managed to load other STEP files, so I don't think I'm being stoopid but will accept that I may indeed be doing something wrong . . .
Thanks.

@t3p3tony thanks

@phaedrux Sorry to keep asking questions but can you tell from the photos if the PCB is the latest version? Thanks!

@phaedrux Thanks for the update. I do have a well tuned Prusa i3Mk3S so I can see how I get on with printing a new housing. I don't foresee any issues . . .

The sensor and my Duet 3 Mini 5+ are destined for a new machine that's currently being built so I won't be able to test it for a while.

I might write to the supplier to see if they have something to say about the housing - I assume they must have sourced the PCB from Duet3D?

@dc42 Any news on this?

Thank you @alankilian , that's a most generous offer. I fancy having a go myself first though. I've already downloaded copies of the CAD files and will probably eventually incorporate some sort of attachment bracket to the top of my extruder so that the sensor isn't flopping about. As I run with reverse a Bowden then perhaps it can stay on the spool holder rather than be fixed to the extruder. I'll enjoy finding out!

My main concern and the reason for the original post was to make sure I was sent the genuine article. The earlier post from @dc42 confirms that the PCB is genuine. We wait to hear how the housing arrived as it did . . .

Thanks again for your kind offer.

Thanks @dc42, looking forward to finding out what you think...
It's reassuring to know that the PCB is genuine!
