Are you #including rtapi.h ?

Thinking about it, you can probably use the buuilt-in EXPORT_SYMBOL in kernel modules (ie, if using RTAI). But in uspace this may be re-defined to be something else. (as suggested by the code you posted)

If you want to be sure that the spindle is actually stopped, then use something like a HAL "wcomp" to provide a "true" signal when the spindle encoder velocity is very close to zero.

For rigid tapping i need only index signal from spindle shaft
A-B signals can come from elsewhere the encoder is mounted that is not 1:1 ratio correct ?

As I said there, you only need the index on the spindle shaft (or 1:1 with the spindle shaft) for multi-pass threading.

Hello
I ran a test to verify the problem I have,
that is: on the A-AXIS output (join 3) there is no signal

I enabled all the axes in the .ini .hal file inverted in the nvem-rt1052.txt file, the joint 3 pins (A-AXIS) with the joint 4 pins (B-AXIS)

it happens that joint 3 and joint 4 are inverted and on the B-AXIS output I find the joint 3 signals working, while on the A-AXIS output the join 4 signals do not work,
on the C_AXIS joint 5 output the signals work

it seems that the A-AXIS output on the NVEM card is physically interrupted, is it possible?

Hi,
I have prepared the hardware to check if yours is a hardware or software problem. Could you please tell me where you got the files from?
I have now used this link: github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic
and the machine works even if there should be a better setup for the servos, but the signals arrive for XYZ.

hi
i have the same card and i connect it as described, with the configuration file nvem-rt1052.txt
but Z-AXIS with dir that doesn't work, it only turns in one direction, while A-AXIS doesn't work.
i would be happy to have your feedback to understand what's wrong thanks
thanks

Ok wenn du mit Linux arbeitest wie auch immer…
Must du dich etwas mit den Linuxprogram aus einander setzen.
Es ist alles etwa leichter wie for 10 Jahren heute geht einiges doch sehr Anwender freundlich.
Auch gibt es sehr gute Beschreibungen im Netz.
Normal ist das nicht das Firefox auf einmal in Englisch ist…
Ich denke es besteht ein Zusammenhang der falschen Zeit
und Firefox in Englisch.
Vielleicht ist die Länderkennung Enlisch Tastatur Deutsch das geht
Das habe ich bei mir gemacht weil ich in Plasmaprogram probleme in Deutsch hatte und in Englisch nicht hatte.

I have a similar (but different) system on my lathe. Mine has a 2-speed gearbox with magnetic clutches to change gear. (The differencce here is that mine _can_ change gear at zero speed)

I have a HAL component that controls this, and actually does rev-matching (ie, it will shift when the ratio of the shaft speeds matches the gear ratio)



Gearchoice.comp is here: github.com/andypugh/HalComps

This looks very odd. It looks like a gmoccapy glitch, but can you try the same sequence in:
1) The gmoccapy lathe sim config
2) The axis lathe sim config
And see if you see the same behaviour?

Thank you very much !


Work!

The problem was related to the Ethernet settings. It was solved.

Yes. but do not wire EN, on most of these types of drives EN is not Enable, it is Disable, so sending signal to EN will actually disable the drive.

Hello everyone,
I wanted to connect my NVEM V5 RT1052 with this DRIVER (just to test the outputs not for daily work). I am not very expert and I do not know how to connect this type of connections, in the NVEM manual there is no this type of driver.
 
 

I think but I'm not sure if it goes like this:

I was able to test the debian 13 image with cia402 ethercat drivers, i can home the machine but after a few jog movements i got following errors and couldn't move the machine until i restart linuxcnc, latency is the same as my config that can runs in LinuxCNC 2.9.4. the only time i was able to run a gcode it only made the first g0 movement.it shows all the time wired connection loss, the only wired connection is to the ethercat drivers. i can run the same machine on the same pc only booting in LinuxCNC 2.9.4. without any erros, so its not a hardware problem.

Yeah... there is no contact with the ECL16DP. Only with the S1-M20.
What can you do? Power + ethernet connection. Maybe you can connect only the ECL16DP? Use the ETH0 port.
That new xml looks to be the same, except for the imagedata that looks intimidating. But it's just the bitmap of a picture that TwinCAT uses to display with the unit.

Hello,
I am installing ethercat but the communication light with the drivers is not flashing and it is not communicating with the drivers.
