Milling Machine

So will this manual encoder work?  There will be no mechanical device for the M19, it must be electronic.  This signal in LinuxCNC is what input-index can I check in halscope (halscope>pins>encoder>input-index)?

 

Yes, that encoder will probably work.

But, this is a retrofit isn't it? And the machine already has a tool changer?

So, how did the original controller align the spindle for tool change?

Does it even need it?

Ah, now I believe I really understand your question….. Yes the machine is a Retrofiting, however it originally had a high and low rpm gearbox, and the maximum rotation was 6000 rpm.  I bought it scrap and it came without the spindle motor, this 15,000 rpm Mitsubishi I already had and I decided to change the entire mechanical project to direct-drive and eliminate all that mess… As it is a small machine with a table size of 800 x550 mm I decided to leave it with more rotation.  That's why the old encoder used for M19 was with a belt and a maximum of 6000 rpm (I tested the signal from the original encoder and it was bad too).

OK, that makes sense then. Have you found somewhere to mount the encoder? 
 

Yes, I will put it directly on the back of the motor, so it will be well protected against contamination, dirt.
