Ahh... that's where the Forum poster

(forum.linuxcnc.org/24-hal-components/566...6eu-hal-and-ini-file) 

got 2.9 pre

The HM2_eth driver from that version also has bugs with 7I76EU configs
(it gets the name wrong)
 

You can look at the manual, but this was definitely  the case at one time.

Edit: the ENA input is actually an active low disable input, that is, it disables
the drive when pulled low. If unconnected, the drive should be enabled.
Is the interface PIN 16 (+24V IN) connected to +24V?

A quick way to check if the drives are enabled is to see if the motor
shaft turns freely. It should hold position if enabled but turn freely if disabled.


Not related to your lack of motion, but to safety:

Its fairly awkward that ENA needs to be powered to disable the drive, but a possible
working arrangement would be to add a pull down resistor on the ENA input so its
normally disabled and then drive it high with a 7I76EU output to enable it
(A 1K 1/2W resistor should work)

Yes I have DMM Dyn 4 servos.

So the drives are disabled when the enable input is powered? This seems backwards to me. So would removing power enable the drives?

If your current hal file is like the older one, enable is
controlled by joint.N.amp-enable-out. This will be true anytime
LinuxCNC is in the run state. 

From the older hal file:

net x-enable <= joint.1.amp-enable-out
net x-enable => hm2_7i76.0.stepgen.01.enable
net x-enable => hm2_7i76.0.7i76.0.0.output-01


Didn't you mention that you had DMM drives?

AFAICR, these are disabled when the enable input is powered.

A better question I should ask is what kind of response or voltage should I see on the ENA pin when the jog is made? It's looks to be 24V and not changing.

Thanks

i successfully updated to 2.9.4.  My pins are labeled as 7i76e now but i believe that is due to me picking 7i76 instead of 7i76e in pncconf. 

However, I'm still not getting the motors to move.  It's changing the DRO and display in Axis.  I see voltage changes in Dir and Step pins but nothing changes.
Any ideas?

Thanks

Found it...looks like i have the wrong version?

Where can i download the correct version?

Where can i see the Linux Version?


therman@Debian-LinuxCNC:~$ mesaflash --device ethernet --addr 10.10.10.10

ETH device 7I76EU at ip=10.10.10.10

That's very odd

I am assuming this is LinuxCNC 2.9.4?

I just tested 2.9.4 and a 7I76EU an the pin names are all prefixed with hm2_7i76e
as expected

What does

mesaflash --device ethernet --addr 10.10.10.10 

report?

 

I did a complete uninstall and reinstall of LinuxCNC. After I went through the wizard and selected 7i76e, I ran LinuxCNC again and i got this error message;

./PM833TV.hal:10: parameter or pin 'hm2_7i76e.0.watchdog.timeout_ns' not found
Shutting down and cleaning up LinuxCNC...

The only way to get rid of this error is to change 7i76e back to 7i76 in the Hal and Ini files.  It doesn't like any references to 7i76e.

Is this the source of the issues?

Attaching my current Hal and Ini files.

OK that's not going to work as most of the pin names are wrong.

I would suggest using pncconf (choosing 7I76e) and starting over making a new configuration.
(7I76E hal/ini configurations are identical to 7I76EU hal/ini configuration)

pncconfs default values are correct for most things 

Do not use AI for this as its just a huge time sink

 

current Hal and Ini files attached.  i attempted to replace 7i76 with 7i76e or 7i76eu but it didn't like that either so i've kept everything as is.
Thanks
 

7I76EU pin names are identical to 7I76E names

Can you post your current hal/ini files?

it's possible...i measured 24V on the output pins.....these lines look different then when the machine was last operational but i had ChatGPT produce these...they don't seem right to me but i don't know enough...my board is a 7i76EU so i was thinking of replacing 7i76 with 7i76EU......if i comment these lines out the z axis brake doesn't release...
