The newest version was already installed, but I get no reaction.
At the start of LCC I get a list with pins, but only a part of the existing.
It ends with P3-17 or Pin50 (P3--
And in the last line hm2/hm2 7i76e.0: registered
If I send ping, the 4 user leds count digitally up, so I think the communication is ok.

My fault, I get a list, but only after LCC is quitted.
I think thats the proof, that I have communication.

can you post what linuxcnc prints at startup?

That's all correct but it indicates the the field I/O is not working

so do you have

1. Field power (>8VDC, <32VDC) on TB1

2. W1 left CR8 on

The screw on TB1 was loose and I don't know if W1 is on. I couldn't find in which position is on or off.
Its in the left hand position.

So after connecting the field power properly, verifying that W1 is in the left hand position (7I76E manual
pages 2 and 13), and verifying that you have a valid field power source (>8VDC and <32 VDC)
and that CR8 is on, do you have remote I/O pins available in you HAL file after starting linuxcnc
(halcmd show pins)

I get a long list of pins, but don't know a possibility to save them. Nearly none of the many descriptions say me anything.
I haven't found anything with remote in the name.

The principle function seems ok, because I have used a LED to see if I have tension on the clamps. If I use an axe key the corresponding led lights up. But I get often a joint 0 or 1 error. Don't know what this is.
I have changed the parameter from up/down to step dir, then it works, but if I disable velocity mode, I get the joint Error in the same moment as I touch the axe key. I have tried to run the demoprogram, but get immediately the same error.

Remember when I said you would need to widen the ferror limits if you dont have the DPLL?

The ferror limits in those example files (that assume a DPLL) are quite small

I've tried to change Ferror without success, than I tried to reduce the speed, that works, but the speed is reeeealy slow.
After that I changenged the speed from setup to the working speed, but that don't works. I get half a dozen errors, beginning always with low voltage, although my field power is 24V with 2Amps.

Did you make both ferror and min_ferror larger on all axis?

Is your 24V supply _filtered_ DC?

You are not likely to get low voltage complaints unless your field power supply has issues
