I ask because SSI support has been working for at least 10 years
though possible only with multi-turn encoders

The scalemax para should be accessed by '''hm2_7i80.0.ssi.00.zencoder-scalemax```
It's my mistake. I read manual and it is hm2_7i80.0.ssi.00.zencoder.scalemax

it is :
Code:
~/linuxcnc-dev/src $ halcmd show all | grep ssi 29 bit OUT FALSE hm2_7i80.0.ssi.00.data-invalid 29 bit OUT TRUE hm2_7i80.0.ssi.00.steps 29 bit OUT FALSE hm2_7i80.0.ssi.00.steps-not 29 float OUT 0.02197802 hm2_7i80.0.ssi.00.zencoder ==> z-pos-fbss <== hm2_7i80.0.ssi.00.zencoder 29 bit RW FALSE hm2_7i80.0.ssi.00.clock.invert_output 29 bit RW FALSE hm2_7i80.0.ssi.00.clock.is_opendrain 29 float RW 300 hm2_7i80.0.ssi.00.frequency-khz 29 u32 RW 0x00000002 hm2_7i80.0.ssi.00.timer-number 29 float RW 1 hm2_7i80.0.ssi.00.zencoder-scalemax hm2_7i80.0.ssi.00.clock.invert_output hm2_7i80.0.gpio.012.invert_output hm2_7i80.0.ssi.00.clock.is_opendrain hm2_7i80.0.gpio.012.is_opendrain

hi,

in manual itt is:
Code:
b: (Boolean) No Parameters. u: (Unsigned) (float, r/w) hm2_XXXX.N.ssi.MM.<name>.scalemax. The scaling factor for the channel. s: (Signed) (float, r/w) hm2_XXXX.N.ssi.MM.<name>.scalemax. The scaling factor for the channel. f: (bitField): No parameters.

maybe, we need to change this in the manual.

Sorry for my mistake.

thank you very much

I saw your pull request for the docs.

Looking through the code, there is no occurence of .scalemax anywhere, so we can just change the doc to -scalemax.
