Hi guys just an update it should have 2 separate ones one counts the large slot and one counts a single slot. so two go one plug. still unsure what to buy something like this? but pre wired ones as my soldering ability

hi
thanks for the feedback,
for testing I downloaded again from the link you posted, I loaded the configuration file that is in the folder, the I/O seem not to be suitable for the NVEM, however dir/step are suitable,
my result does not change XY works, Z pressing forward and backward only turns in one direction, the dir channel does not work, and I think that by also setting the A axis it does not work.
I think it is a hardware problem.
thanks
 

Hi, I used your configuration by copying your files to mine and all the axes work. Did you get a board with only 3 axes? Or do you have a 6 axes? Because the manufacturer could have not soldered the bga. Or simply there is some faulty circuit, I don't know if there are opto-isolators in the output but there should be.
but I didn't compile any hal file like this  "nvem-rt1052.hal"

I hope this is the right thread, please move if it isn't...

I'm investigating converting my NUC to a Pi 5 - the install from the official Pi5 image went perfectly but as I'm using a Mesa 7i96 and the Pi will end up inside the cabinet, I need to use a USB WiFi adapter for its external antenna.

The dongle is a Reaktek RTL8811AU (external antenna'd ones seem to be getting rare) so I think I need to install this: github.com/lwfinger/rtw88?tab=readme-ov-file#installation-guide Happy to be corrected if I don't because I'd rather not.

If I do aI get 6.12.11 but this:is "Unable to locate package linux-headers-6.12.11"

An apt search reveals a bunch of 6.1.0x Linux headers and a few 6.12.12+bpo headers but no 6.12.11. Not sure what to do now, so any guidance would be appreciated - even if it's a link to a natively supported USB WiFi!

Edit: Runninginstead of apt searching for 'linux-headers-6' reveals 'linux-headers-bcm2712-rpi/now 6.12.11-1 arm64' are already installed. Why the headers don't match the uname -a is slightly above my pay grade.

I guess there is a problem with the hall configuration. Today I broke 2 carbide inserts. After 10 made parts the axis started to move with a larger feed. But not too much, maybe 20-30% more. I tried in simulation but I don't know how to load my configuration into the simulation. There is no problem with the sample configurations.

So that everyone is on the same page, would you mind providing the filename and
the exact line to comment, please?

Thanks in advance.

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 ?

forum.linuxcnc.org/49-basic-configuratio...oder?start=20#326827

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!
