Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

Hi
the board is a 3-axis, but I don't think it depends on that, I think.
Ultimately, on six axes XYB working, Z and C turning in one direction, dir doesn't work, A doesn't work.
I haven't had any luck....
this is the second board, the first one in understanding how to flash it I must have made it unusable, I can't get it back.
I don't want to buy another one, never mind.
Thanks for the feedback
 

try this:
mkdir ~/linuxcnc/configs/remora-rt1052-test
pair the contents in this dir:
github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic
download this: github.com/scottalford75/Remora-RT1052-c...xCNC/nvem-rt1052.txt
python3 upload_config.py nvem-rt1052.txt
pair your files:nvem-rt1052.hal,nvem-rt1052.ini
then: 
and try again please

amplifier fault troubleshooting

Category: Driver Boards

I recently started working on finishing a plasma table retrofit that was put on hold for about 6 months.
It has servos, a hypertherm hsd 130 (I believe HF start), and a mesa 7i97t.

I thought I had it ready for a trial cut, but when the torch fired, I got an error.
error finishing read! iter=172124.
I tried again with the same result. I eventually realized that I had removed the torch start relay and diode, and instead hooked the torch start wires directly to the 7i97t. (Not for any good reason, I just kinda forgot what little I had figured out from 6 months ago and was hastily making wiring changes.)

Despite not making any changes after my 2 failed test cut attempts, I am having a new problem.
Now, after I start linuxcnc, when I hit the power button at the top of the plasmac screen, I immediately get joint 0 amplifier fault.
The DRO stays at 0 for all axis's when physically moved, but the amplifiers appear to be on and displaying encoder counts correctly on their little read outs.

I'm worried I damaged the 7i97t, but don't know where to go from here. Any advice is appreciated.

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"

Linuxcnc & the Raspberry Pi (4 & 5) Official Images Only!!!

Category: Installing LinuxCNC

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 a
uname -r
I get 6.12.11 but this:
sudo apt install linux-headers-$(uname -r)
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: Running
apt list --installed | grep headers
instead 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.

A simple question: How to use EXPORT_SYMBOL()

Category: General LinuxCNC Questions

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.

spindle with encoder

Category: Basic Configuration

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.
