This 3” Drive is a direct drive model so no drive belts Chema. I have managed to get it to fire up and the LED’s light up correctly. All I get now is “ Insert system disk “ and after a while “ No operating system on disk “ so I have made some progress. Maybe the drive is out of alignment?
I know my CPC6128 had alignment problems.

Ah, indeed. Did not remember that.
Yep. The No Operating System on Disk means it located a sector and read something without giving a read error. What did you do to make that progress?

I also guess you checked for current consumption, just in case... you can find some reference values for both the 5 and 12v in standby and in operation in the manual linked in a previous post.
Re: Issue 2 Oric-1 Repair
I took the 3” Drive apart and disconnected the logic board. The Index light sensor was pushed down so I straightened it up. Reflowed the pin headers for the connectors. Refitted it all back together and stuck a disk in and saw the LED and heard it spin up. So I didn’t do a great deal but something I did helped get it a bit further along. It doesn’t sound like the head is moving trying to find track Zero though so there is a ways to go.

Re: Issue 2 Oric-1 Repair
It may be already on track zero, so doesn't need to move. Provoke it (carefully) by manually winding the head out onto the disk, then see if you get a nice satisfying seek-to-zero noise. Some heads will just slide if pushed, others need you to rotate the stepper motor for the worm drive. No forcing/breaking things! That will tell you if it the STEP and DIRECTION and "Track 0 detect" are doing something useful.
Re: Issue 2 Oric-1 Repair
I was thinking of setting the Internal 3” drive to be drive “B” using the dip switch and connecting my Gotek as drive “A” that way I could load Sedoric and see if I can get the internal drive to do a “DIR” or format a spare 3” disk I have from my CPC.
