Hi All,
I need to buy a Differential Rotary Encoder to put on my mill spindle but don't know how many PPR (pulses per revolution) encoder to get.
I'll need three phases: A, B, and Z for the spindle index.
The UCCNC V1.2111 software I am using defaults(?) to 400 PPR but I have no idea what spindle speed that might be related to.
My spindle is 6,000rpm maximum so I need something that will cope with that and control the spindle speed correctly, but be fine enough resolution for rigid tapping at tapping speeds.
Can someone recommend a suitable PPR please?
Many thanks,
Davo.
