Help with tandem axis Y

Category: Basic Configuration

No, I have a 7i76e with lots of inputs. I used to have a machine run off a parallel port, though, which has very few inputs.

7i76E Spindle configuration

Category: PnCConf Wizard

I was able to check the connection yesterday, you were right, [GND pulse - dir -] I had them bridged. !!

I always connected them, I understand that it's wrong! I like to learn because the board can get burned with this connection. I thought that the ground from both the driver and the board should be connected.

thank you!!!

However, some errors remain:

I'll try to fix these - however if anybody has a quick idea what needs to be done to fix them your help is always appreciated :-)
Thank you so far for your quick help to get the machine up and running again!

Update LinuxCNC 2.9.5 on debian 13

Category: Installing LinuxCNC

Looks like the latency is worse than Debian 12 (if Debian 12 was working)

What does:

sudo chrt 99 ping -i .001 -c 60000 -q [card_ip_address]

report ?

Where [card_ip_address] is the ip address of the 7I76E

(the command will run for 1 minute and then print statistics)

 I am going to check the connection, I should have connected TB2 pin 2-4 with the white wires [ Pulse - ] [ Dir - ]  from the Driver. 
the pink cable from the X connector seems to enter pin 2, I need to check!!

 thank you very much for the observation !!!!!!!!!!

I'm a bit concerned about the STEP/DIR wiring.

It appears that the thick white wires are grounding the STEP- and DIR- pins
This should never be done as it shorts out the STEP- and DIR- pins
possible damaging the driver chip.

If STEP- / DIR- are unused, they should be left unconnected.

Thank you all for the responses. The VFD GA500 is already installed in the machine and I don’t have it here. I have an LS600 on my work desk which I am using for the tests. I will try to send you the information you are requesting as soon as possible.

PCW !. Thank you for coming back! From the heart!

I advance the board that I am using in the TB4 connector, I believe, as PCW explains, that I am not supplying the 10vcc. I am going to check the LS600.

There is no tension on pins (1-2) (1-3) of the TB4

That means no Spindle output is possible.

The 7I76/7I76E/7I76EU do not supply the 10V.
The spindle output on these cards works as a
potentiometer. Typically the 10V is supplied by
the VFD.

7i76E Spindle configuration

Category: PnCConf Wizard

The OP was supplied with a config as requested for 4axis and a spindle, to 24k I think, by PCW. Even with is he could not get an output, taking this into account PncCONF is not the issue.
If the OP could be so kind as to supply a picture of the wiring of the actual spindle connector and a diagram as well of how he wired it I think that would be quite helpful. This is the second time I have made this request.
To OP seems to have missed or ignored the bit about PWM not being involved in configuring the spindle.
Just making a guess I suspect that spindle + and spindle - are not being supplied with an isolated voltage. If this is the case spindle out with not have a voltage that is in line with the selected spindle speed.
Wiring of the opto isolated outputs can be tackled later.
To reiterate the OP has a config supplied by PCW, which we can take as being gospel and if the board is wired correctly will work.
For testing I would not have the spindle connected, I would just be monitoring the spindle output with a multimeter referenced to spindle - .

This is actually how I went setting up my spindle, but using a smart serial board as I required the servo driver to be some distance from my 7i76 and did not want a small analogue voltage being transmitted over a long cable. Paranoia may have had been high that day.

So, as a user, I wonder why the PncConf Wizard application did not provide me with the TB4 configuration. And that is my problem to solve.
 

Try setting Locale to UTF-8, google how to do that on Debian.
That is almost always a locale issue and/or language issue, so for future reference you can boot from USB with LinuxCNC and use Live session to create a PncConf config while in English language, and also test the machine if it is attached to that PC, all from a Live session, but do not forget to save/copy that config to the internal hard drive/SSD/NVME. Then you can reboot and use the existing installation in your language to run that config.
