The STM32 chip has hardware quadrature decoders. These are a set of
flip-flops and counters that exist on the

If the joint limits where being ignored then the problem would be that
the joint limits were being ignored, not just "no motion".
The way I would debug this is to program one joint at a time. Get the
base joint to work in world coordinates first. Figure out what
happens when you give it a

hi andy, do you believe that could be a mistake in the DH parameters?
I would like ask you, how does the genserkins define the limits of the
robot in the kinematics? i ask you that because we entered the limits for
each joint in .ini file but ¿does the genserkins take these parameters in
Thanks to Andy and Peter io is working
In the end it was to things not quite right:
- Vin was off on TB1 pin 5 (unable to communicate with field IO)
- Syntax errors in Hal (functioning Hal below)
Hope this is some use to some one in the future.
thanks again linden

It should probably be

Hello All
I have tried as Andy suggested and changed the line in the Hal file see
current line below along with complete error message from terminal below.
I now get an error "parameter or pin 'hm2_7i76e.0.0.7i76.0.output-00'

Note that I don't have, and have never even seen, a 7i76E.

Greetings Peter;
The 7i76d has a spindle encoder, so I'm looking for suggestions as to how
to drive it.
The ER11 chuck has doubleD flats, but placing ATS-667's there precludes
using a wrench to tighten a tool, so thats out.
The top/rear of the ER11 has a slinger disk around 1.25" in diameter,
