My guess is that it's trying to mount the nfs share before the wifi interface is up.
So you may have to look through dmesg to see when the nfs share is being mounted and when the wifi interface is being brought up.
Do you have any issues trying to mount the share after the wifi network is up ?

There may be a way to do it via systemd that waits for the wifi network to come up, I've got a couple of ones that turn off the power related stuff for wifi, but only after the interface is up. Might be able to use the same mechanism to mount the shares once that interface is up.

I'd suggest this isn't a issue related to the Raspberry Pi platform but any situation where an nfs or samba share is automounted and the required interface isn't up at that time.

Trying to get nfs between workstation and mill.
Posted here hoping the RPi developers may have a solution.

nfs server - workstation: hp desktop ubuntu 24.04.
nfs client - mill: RPi 4B 4GB LC 2.9.4.
 
wifi is working fine.
sftp between the stations without issue.

nfs works after a manual mount on the client.
Cannot get nfs to mount automatically at start up.

The /etc/fstab file is populated (to the best of my searching).
Tried a couple of web suggestions, but no solution yet.

Looked through the startup log:
    - "mount.nfs: Network is unreachable".

Tried several web suggestions, including increasing the wait time.

Did some searching on the Raspberry Forum without success.

When I issue a terminal command "mount' after starting LC, there is a response about an old version and to use "systemctl-daemon reload".
After reboot, entered 'systemctl-daemon reload', got 'command not found'.
Tried 'systemctl daemon-reload', accepted without success.

Any suggestions getting the mount at start-up ?

I was using Octopus Pro Board for LinuxCNC. That one is giving some problems. So I bought new board BTT SKR3 so that I can use TMC5160. Can anyone help me setting up its config.txt and LinuxCNC configuration. And connection diagram. I have wired it as per SKR2 board. Pinouts of both boards seems similar. I cant get Machine out of estop. I think there is no communication between rpi and skr3.

I'm having the same problem. Got on using the .org just a while ago and now trying the 162.243.45.186. I will see if works any faster.

You are correct, not much there.

OK so if you are supplying the same 24V to TB3 and TB1
the 5V and 24V grounds are already common so that's OK.

Does hm2_7i76e.0.7i76.0.0.enc0.count change when you turn the MPG?

 

I already have

And from my post above, I wrote :

but I meant:

is the GND on pin 9 floating and I need to wire it to the GND from my power supply?

bit lost here...

For the MPG wiring you would also need the field power common
to connect to the MPG GND

Hello guys, 

Trying to set up two things :

1) I want my machine to be enabled as soon as I disengage the estop, so halui.machine.is-on is true when the estop is not pressed.

I already have this 


I tried a lot of different ways but unsuccessfully. The most I could do was that the machine was on at start, when the estop was not pushed, but after cycling the estop, the machine would not get back to its on state.


Can you guys tell me why it does not work, what I am doing wrong or forgot?

2) I tried adding an MPG, but I am lost and the documentation is not very helpful for a beginner.

I am wiring my mpg as described in the attached picture but I was not able to make it work :

 

Here is the wiring for my pins on my mesa 7i76e :


So, if someone has the code for an mpg wired like that, on a 7i76e, I would really appreciate it!

My ini and hal files are attached.

Yes, sounds like its working now, sorry I missed that the index was single ended.

The 7I33 can just change the input mode of each encoder interface (A,B,IDX), not pin-by-pin
as most newer Mesa cards can do.
 

So I set the jumpers on the 7i33 for X- and Z-axis to TTL (DOWN) and entered the USE INDEX- YES in the INI. Both axes behave normal and I think they home with using the index now.
Sequence:
Homing movement
Home switch trips- "home sw. X" gets yellow, "enable index" lights up yellow and the axis moves forward a bit further.Then the "hm2_7i80.0.encoder.00.input-index" flashes yellow very short, the axis frees the home switch and moves on to home-pos, stops and "x-axis homed" lights up yellow and the DRO says 0/0.

Z homes the same way. 

I think thats exactly what I wanted to achieve- correct? 
The spindle I guess can be indexed also, otherwise threading would be impossible...but the spindle likely just needs the index, A/B will not be necessary on a lathe- or am I wrong?
Well lets see how the next step can be solved.

The important hint was that the 7i33 just can process ALL inputs as TTL or ALL inputs as differential!
Thank you all so much
Sigi

Hi, please share your config files. If signals can be seen in Hal Meter there must be another config issue.

Does individual joint homing work?

(comment out the HOME_SEQUENCE settings in the .ini file)
 

Here's a basic try at this using the stepgen mapping:

0 = X
1 = Y
2 = Z
3 = A
