I bought this and a Linkstec PCI parallel extension board, but for Linux source code needs to be compiled for the driver, and the compile throws syntax errors.

Can anyone recommend a card that will definitely work with this? I've installed the latest 2.9.2 version of LinuxcncHP EliteDesk 800G1 Mini Tower Desktop Computer PC, Intel Core i5-4590T, 16GB RAM, 256GB SSD, 1TB HDD, NVIDIA GT730, WiFi, Bluetooth, DVD, Win10 Pro (Renewed)

I managed to identify one of the problems, it was in the name of the INI and HAL files, but after correcting it and trying to run Linuxcnc it showed an error.
The error report file is attached...

Gave my idea a shot on WT32 ETH01 but still have around 0.6ms of latency (bare esp-idf, any memory allocations outside the loop, basically just recvfrom() -> polling SPI transfer -> sendto() in a loop).

Have ordered W5500 module, will give it a try as well.

The consistence on the IRC is just install flexgui and LinuxCNC should find it even if running a RIP.

I've never tried to run flexgui in a RIP, let me experiment a bit. Heck I've not even built a RIP in years...

Thanks a lot. I had to go to the airport to pick up my wife, and have a two day work trip tomorrow, so it will be later in the week before I can try it.

Hi Jt,

How to run the flexgui in a rip environment? qtvcp axis run's. qtvcp dependencies are installed.
I don't know where to copy the files to.

Hi everyone,
apologies for starting a new thread with an issue that was outlined elsewhere as well. After extensive analysis, I have come to the conclusion that my problem may be elsewhere.
Setup:
- Deb12 with most recent EtherLab master and most recent package of linuxcnc-ethercat/linuxcne-ethercat running 6.21-rt kernel with LinuxCNC 2.9.2
- Total of 16 EC slaves including various Beckhoff devices, a custom slave, Delta drives and a Delta MS300 series VFD with a Jianken Spindle (Slave ID 9)
- VFD has a CMM-EC01 (according to ethercat slaves -v)
- Spindle: 4 pole spindle with 380V, 7.5A, 4.2 kW
- Topology: VFD ist connected to EK1110 coupler as a single item branch, tagged position 9
- Spindle and VFD have been tested using the manual input on the VFD and are known working. VFD parameters have been reset prior to testing (multiple times).
- VFD parameters are default as far as possible. Spindle related stuff has been setup, 00-20 and 00-21 have been set to accept the CMM module as master frequency and operation command, 9-60 confirms that the VFD recognizes the EC CMM card.
- One thing I could observe: While I do not have the keypad, there is an option to display all keypad information via USB. The VFD indicates that it is in JOG mode. No idea how to get in out of there.

Situation:
- When starting linuxcnc based on this config ( my repo, ethercat-conf.xml )  all slaves go OP (takes a couple of seconds)
- Beckhoff slaves and custom slave behave as expected
- Spindle.0.xxx pins connected to lcec.0.spindle.xxx pins as seen in examples - see following hal file: spindle.hal
- Delta drives in this setup untested, on the test bench they were known to work fine
- Ethercat pdos and ethercat slaves -v export attached as photos
 
   

- I have not had the issues of not seeing any PDOS to which an alternative SII binary was suggested here: forum.linuxcnc.org/ethercat/45099-trunca...-bit-signed-integers
I have tried the linked binary to no effect. I have tried using the Init commands as outlined in the example repo above to no effect (I admit that I do not fully understand those)

Issue:
When setting a spindle speed (S1000, e.g. 1000 rpm) in MDI and issuing M3 afterwards the following happens
See halshow below for parameters and values:
 
1) VFD shows output command frequency as 333.33 Hz --> This is od, because it is scaled by a factor of 10! 33.33Hz would be correct as this is a 4 pole spindle
2) Nothing happens. No movement of the spindle, instead: Looking at hal show it becomes apparent, that the driver is stuck on stat-switch-on-disabled
At this point: No error messages on the VFD, no Fault via EtherCAT

I am lost (to say the least) and have been for days now. Does anyone have any pointers?

I think I figured something out.

- When I add G61 into the gcode file, the problem disappears.
- If I then remove it again and start the file again, the G61 setting is remembered.
- If I then turn the machine off and on again using the button in Gmoccapy, the problem re-appears - no emergency mode needed!

So for some reason, switch off the machine using Gmoccapy clears the G61 setting, causing this issue.

Man, finally. So the "solution" is indeed to put this into every gcode file - that sucks, because how on earth will I ever remember that. Now I'll have to go through every gcode file I ever created and add that setting, not very practical.

Any alternative recommendations?

I actually had already added G54. attached is my current ini and 3 hal files. Also of note, there is no blank.ngc on my system that i can find.

Can you run LinuxCNC from the command line
to see what startup error you get?
 

Reviving this old topic, as I ran into this again .

Here's what my path looks like in FreeCAD:
  

Here is what the machine says it will do (note that I made this picture too late, when the first incorrect traced path was already removed from the view; but you can still see that the later chamfering path had the same problem, just with a smaller radius):
 

And here is what the machine does:
 

As you can see, what is supposed to be a square path becomes an arc.
Interestingly, the gcode preview shows the intended path correctly, but the pink line tracing the actual path is shown rounded, too.

Here is the relavant part from the gcode that is supposed to make the outer square:

So the machine never actually attempts to drive to this point:
Note that I added G61 after the problems a year ago:
RS274NGC_STARTUP_CODE = G17 G21 G40 G49 G61 G80 G90 G94 G97 G98

My full machine config is here:

The 220 ohm resistors would be connected between the A,B,IDX inputs
and encoder ground (TB1,TB2 pins 3,11,19)


So for example for encoder 0 signal A:

Encoder signal  A --> 1K resistor --> 7I97T TB1.1 (A)
7I97 TB1.1 (A) --> 220 ohm resistor --> 7I97T TB1.3 (GND)

That looks like a parallel port operated step/dir machine
so probably the simplest option is to use a PC with a parallel
port to control it.

General purpose USB --> parallel port adapters will not work
with LinuxCNC.
