Subject: number of closed loop stepper axis.
Hello

Is it possible to have 6 axis of closed loop steppers, with just the kflop board?

I am looking at the connector diagram for the kflop JP5 connector and the chart shows each pin being used as a step and direction pin or an encoder pin for each channel. 

Could I simply select a different input channel then my output channel when setting up my axis?  Eg: use input channel 7 with output channel 4?

Thanks
Troy

Hi Troy,
 
Yes.  Just set the Encoder InputChan0 and Step/Dir Gen OutputChan for the Axis Channel appropriately.
 
There are also other options to mux (move) the encoder inputs from JP5 to JP6 - set bit8 of FPGAW(ENC_NOISE_FILTER_ADD).
 
Or to Mux the Step/Dir outputs from JP5 to JP4 and JP6.  See:
 
In those cases it is possible to have 8 closed loop steppers.
 
Regards
TK
