Hi Albert,
Option #1 is correct.
Option #2 is not stated correctly and will not allow 8 Step/Dir Generators and 8 Encoder inputs. Rather it moves the 4 Step/Dir Generators from JP7 to JP4 and JP6 (2 each). This is useful if you still want to have Kanalog connected and still use the Step/Dir outputs normally on JP7. But there will still be a conflict with shared Encoder/Step/Dir pins on JP5. 6 CL Stepper axes are possible in this mode.
Sorry this is so confusing but we are needing to fit a lot of options into a limited number of pins.
Regards
TK

Hi Tom
If I want to have 8 closed loop steppers:
First option: Mux JP5 to JP6 encoder inputs, set bit8 on FPGAW(ENC_NOISE_FILTER_ADD).
JP6 Encoder inputs now:
IO26 - IO33 EncoderInput 4-7
JP5 StepDir generators:
IO36 - IO43 StepGen 4-7
JP7 unchanged
JP4 unchanged
Second option: Mux JP7 StepDir generators to JP4/JP6 (FPGA(STEP_PULSE_LENGTH_ADD)=32 + 0x40)
JP4 StepDir generators:
IO22-IO35 StepGen 0-3
JP6 StepDir generators:
IO26 - IO33 StepGen 0-3
JP5 StepDir generators:
IO36 - IO43 StepGen 4-7
JP7 Encoder inputs now:
IO0-IO15 EncoderInput 0-7 ??
Is it correct?

Hi Albert,
This looks like a re-post of a previous message that we answered here:
