# The Step signal for my machine is inverted. I tried to remove the inversion from the step signal, but than the Stepper don´t move at all. Does that make sense??

please check your Opto-Outputs, perhaps they are too slow for the short pulses. ?!?!

EDIT: and please add you config

Hello
Im trying to include my own tab to flex gui touch (great wotks! Thanks to author!). I see that already there fsc_container which corresponds to /usr/lib/libflexgui/fsc.ui and now i wanna to add my own tab - for example i have some rs232 device to read some  parameters (thc, edm for example, device already connected to hal via user space component linuxcnc). And i dont understand how to include thc.ui to the tab like dsf / fsc ?

My config, original non-auto line commented out new auto one below
#192.168.1.70:/exports/share /nfs/share nfs users,noauto,hard,intr 0 0
192.168.1.70:/exports/share /nfs/share nfs users,_netdev,auto,x-systemd.automount,x-systemd.requires=network-online.target,x-systemd.device-timeout=5s 0 0

Thanks for the response.

Changed the parameters in the /etc/fstab entry to:
defaults,x-systemd.automount,x-systemd.mount-timeout=30,_netdev,x-systemd.after=network-online.target 0 0

This works fine, thanks.

"automount nfs but wait for interface to be up" is a google search phrase that brings up some good answers. Apparently there are some options you can add to fstab to help out.

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.

Guten Morgen.

hat niemand Erfahrungen?

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.

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.
