What would it take to merge the Tormach TP into LinuxCNC? 

That's a good question, and it's something I want to look at. 

I did get as far as making a hack-job combination of LinuxCNC and Pathpilot:

github.com/LinuxCNC/linuxcnc/compare/master...Tormach_9_axis

If you are an experienced C-coder with time on your hands.....
 

The internet is connected, but the browser is not allowed to browse because of the date and time. When I installed LinuxCNC, everything was working.

Looking through halui.cc I don't see anything that would obviously fail if joint 0 is angular.
But as an experiment I would be tempted to switch COORDINATES to ZA to see if anything changes.

It might be instructive to see which halui pins exist, to give some indication on where the component load fails:

github.com/LinuxCNC/linuxcnc/blob/master...mc/usr_intf/halui.cc

Assuming that linuxcnc is "alive" "halcmd show pin halui" should give us a pin list to look at.

I think that, if you connected to the internet, the date and time would correct themselves. So I would start with debugging the internet connection.

I have EC3A-IO1632 module and trying connect it with linuxcnc.
I am following instruction from here forum.linuxcnc.org/ethercat/45336-etherc...-how-to-step-by-step and stop at ethercat slaves step.
When trying list slaves with ethercat slaves command I get empty output.Output for ethercat masterI trying different Ethernet cable with same results

I'm not sure, to be honest. I wasn't specifically looking for the ethernet version of the boards, as they don't seem to be the most popular option here (or at least that's my impression).

From what I've read, the ethernet version usually has a 1 kHz refresh rate. My goal was to find the most reliable configuration possible, so if I messed something up, I'd have a solid backup.

No idea how you got to that conclusion as probably 90% of new posts are for Ethernet cards, and i have at least 30 in daily use with no issues ever.
And most ethernet Mesa cards can easily do 4Khz, so there is no difference between the interface types, at least not major differences in use. Also have over 30 of PCI and PCI-E cards in daily use, with no issues ever.

My machine has mpg wheels to control feed and spindle, halui.feed-override.counts and halui.spindle.0.override.counts
Is there a way, to make the sliders follow the adjustement with mpg wheel?

Nice, thanks for reporting back.

Yes, a 7I73 (or other sserial device) can connect directly to the 7I97T

1 KHz is the default LinuxCNC servo thread rate and is typically fine for
normal CNC machines with velocity mode servos.

You can add multiple Ethernet cards with a switch or multiple Ethernet ports

One more problem, LinuxCNC is using 3-axis (xyz) readahead, so if you are using xyz+(abcuvw) axis blending in G-code command, the speed will be very slow

Just wanted to say thanks for all the work on this.  I just got it working on my machine.  I don't have a nutating head, but settings the angle to 90 worked perfectly.  Also, since I have 2 c axis I edited the kinematics to pass through an additional W axis for the rotating table.    

I'm not sure, to be honest. I wasn't specifically looking for the ethernet version of the boards, as they don't seem to be the most popular option here (or at least that's my impression).

From what I've read, the ethernet version usually has a 1 kHz refresh rate. My goal was to find the most reliable configuration possible, so if I messed something up, I'd have a solid backup.

However, now that I'm looking at it, I think it's a good option. It could be used with different PCs in the future without becoming a bottleneck. Do you know of any topics or threads where this configuration is discussed?

for what i read i can connect the 7i73 to the port in the board (using the cable correctly)

And i can add more inputs and ouputs through the db25 connector.

And can i use other ports of ethernet to add more boards or this is a banned move

Also, could someone explain if there's any problem comparing the PCIe to the ethernet versions? After reading and writing this, I don't think 1 kHz is a bad rate for these, and the machine's operation is controlled by the board itself, while the PC only refreshes and corrects some things, right?

Again, thank you guy for your help.

Cheers.

What UI you suggest for marble bridge sawmill machine that cuts with diamond disc ?
3 axis + rotating table.

Just been perusing some of the threads on Flex - really interesting. I'll definitely have a closer look..!

The cool thing about Flex is you don't need to program anything, the center calculator is built in now. Glade is very old and might not work well with new OS's while Flex is based on PyQt6 and is the only gui to use PyQt6 the rest of Qt gui's use PyQt5 which is at EOL.

And I'm from the same old school as you if it ain't broke don't fix it... my Hardinge CHNC runs on Ubuntu 10 with EMC 2.7 so it's 15 years old and works fine.
