Hello all,
So i have this fadal that i try to get up and running for almost a month now. First main board needed fixing, then thrust bearings. But i got machine up and running lately, it looks like we are going to make parts on it for sure just have one last bug left to fix. Latest headache is that i get 22051 error on siemens 840d screen when i do tool change or m19. Checked sensor for orientation(the one that works with magnet) . It gets 24v power and sends 14v and then on magnet 0v. I guess its working good? Spindle lock engages sometimes. Sometimes it orients good sometimes i keep getting these errors. Also every time i power up machine i get notification that belt change is in progress check air preassure. After few reset clicks its gone. Any recomendations what to look?
Also looks like spindle is okay on high and low rpm. Fadal tech guys told me it might be worn out pulley? I guess they are talking about rotating part with magnet? But its not touching, can magnet wear out??

Well let me know what you think or maybe you had similar problem. I see some posts on this issue so i guess its pretty common
