Hi Everyone, I am trying to get scales going on a 7i85.

my last 2 posts are the outputs from show pin and dmesg.

upon review I am confused by the output.

show pin shows encoders 0-5 on the 5i25. though the 7i85 has 4 and the 7i76 has 1

also the output from dmesg seems to show 3.
I am sure this is just me though I am stuck.

any help much appreciated,

-Peter

The reason there are 6 encoders is that LinuxCNCs hm2 driver cannot mix encoder types, and since the 7I85S needs muxed encoders, the 7I76 must used muxed encoders This means that you end up with a dummy encoder (encoder 1) that duplicates encoder 0 on the 7I76 (the 7I85S has encoders 2 through 5)

Hi and thanks for that.

I have the non "S" variant of the 7i85 though I assume the same can be said?

do you have any insight in why dmesg only reports 3?

can you point me to any resources regarding next steps for reading the scales?

Yes the encoder part of the 7I85 is the same as the 7I85S

Dmesg reports the pins for 3 multiplexed encoders (each set of pins for a
muxed encoder supports 2 actual encoders)

What are your intentions for the scales?

Even if you intend to use the scales in the final configuration, I would start with a standard step/dir configuration and get it working before proceeding

That sounds reasonable, I have moved the motors in the test/tune axis configuration screens.
I am hoping to use the mill in a sort of power feed and DRO configuration most of the time, with occasional CNCing.

If possible I would like eventually to get a PID loop going.
Not for lost steps, as much as some backlash compensation
