Pncconf is a bit confusing because the num columm contains either channel
numbers (1 digit) or GPIO numbers (3 digits). One main thing to remember
is that you don't really need to care about in numbers for the main functions.
as the firmware maps these to the proper pins.

With G540 firmware the stepgens for example are mapped in a logical sequence:

0=G540 X
1=G540 Y
2=G540 Z
3=G540 A

So you just use the channel number "NUM" in pncconf to map the stepgens appropriately

Also you can get a list of G540 function  to channel and GPIO pins with:

sudo measflash --device 5i25 --dbname1 g540 --readhmid

 

hey persei8

i am the guy who messaged on facebook about this

this looks awesome

would be great to set this up on a cnc mill when i get time

cheers

You can still use the calculator. The only difference with a THCAD2 and THCAD10/THCAD5 is that it rolls the 2 earlier devices into one and gives you a way to select the full scale range of 10v (THCAD10) or 5 v (THCAD5). So just use the mode that suits your use. Normally you would use a 10 volt full scale for torch voltage

Ive allready tested the last update ...

TP2 and it is working only with simple shapes really well, I did not notice infinity spikes of anything..

no more difficult shaping avaible.. it just froze at cloud of points as G2\G3 transfered to cloud of points .. time spiking increased from last testing

testing only in simulation level ... no real hardware avaible for now

thanks Luca for your job!
 

I only have according to my machine. One setup is my diy, rotary A axis on table(bed slinger) and tilting head rotation in B axis. XYZAB
This is my DIY setup
youtube.com/shorts/E-yx1akYfMQ?si=7jRvSRYxSsq2Lq3P

Other is regular triunion type, XYZAC

do you have a stl machine model for head/head 4th/5th axis? i need to start testing the head head, i currently have all of the table/table/head/table/table variants working as expected, the last bit is for head/head 4/5 to test and then it will be available

Okay, first step: read through the entire thread.
I know there are a lot of pages, but you’ll find a wealth of information here.
Then, step by step.
First, what’s what:
>>> ethercat.xml
provides the information for the LinuxCNC EtherCAT driver (lcnc) – mappings of the signals and registers of the servos to the pins in LinuxCNC

>>> your config.hal
Calls to the LinuxCNC components and internal connections within LinuxCNC

>>> your config.ini 
General configuration 

Setup
1. Connect the servos and troubleshoot issues
> dmesg | grep ethercat asl root
There shouldn’t be any errors here; if there are, you have EMC issues

2. List connected devices
> ethercat slaves

3. Create ethercat.xml
Study the existing templates in this thread
If you don’t understand something, just ask

3. Create your config.hal
Here, too, simply use the existing templates.
Most of the time, you won’t need to change much.

4. Create your config.ini
Here, you’ll need to read through the LinuxCNC documentation.
The configuration is specific to your machine’s setup.
Again, make sure to familiarize yourself with the individual parameters.
If you have any questions, we’re happy to help. 
But please start a new thread for that.

5. Start LinuxCNC 
If there are any errors, you’ll see a message right away.

And importantly, most questions and issues have already been posted and answered in the forum. The forum search will surely answer most of your questions.
If you get stuck, just ask—we’re here to help.

Best regards

 

Thank you. I've also (I think) resolved my problem by refreshing my .ini and .hal files from the repo. I had gotten them totally out of whack without understanding what I was doing. I can now run jobs to completion without the following errors.

BTW this is LInuxCNC 2.9.8 running on a miniPC with Debian "trixie" -> W5500-EVB-PICO board -> Arduino CNC shield with TMC2209 driver modules.

Howdy,

I'm struggling to understand the configuration mapping window in the PnCConf Wizard.

I have flashed the 6i25 with the 5i25_g540x2.bit firmware and reloaded the firmware to make sure the new firmware is loaded.

Based of the manual for the 6i25 card, it looks like P3 is the tab to use to configure what each of the pins on the DB25 connector on the back of the machine does.

Based off this post , it looks like the "num" column in the P3 window is to be interpreted as a GPIO pin number if the number has two leading digits and a function or module number if the number has no leading digits.

I ran "sudo mesaflash --device 5i25 --readhmid" and got following output for P3:
IO Connections for P3
DB25 pin#             I/O   Pri. func    Sec. func        Chan     Sec. Pin func   Sec. Pin Dir

 1                      0   IOPort       None
14                      1   IOPort       PWM              0        PWM             (Out)
 2                      2   IOPort       StepGen          0        Step/Table1     (Out)

 9                     12   IOPort       StepGen          3        Dir/Table2      (Out)
10                     13   IOPort       QCount           0        Quad-A          (In)

13                     16   IOPort       None


So far so good... Only when I look at the P3 tab in PnCConf, not all the I/O numbers from the output from the "sudo mesaflash --device 5i25 --readhmid" are listed (please see attached screenshot). Without all the I/O numbers listed, I don't understand how to properly set which functions should be selected for which pins.

Can I ask for some help please on how to properly use the PnCConf wizard in LinuxCNC to map my axis and spindle to the proper pins for the G540?

Regards,
John



 

Tool compensation (G43 and G41/42) has no effect on the joints. It is applied to the coordinates of the tool's center point in the Cartesian coordinate system of the “Axis”.

It's not entirely clear what you're trying to achieve. need more information about your kinematics and the type of machine (mill/lathe)...

For G43 (Tool Length Compensation), you can apply corrections individually to each axis (XYZABCUVW, but not to the joint) - these are tool length/offset corrections for milling machines and diameter corrections for lathes.

G41/42 - Cutter Radius Compensation, D in the tooltable - cannot be applied individually to axes (these are tool diameter offsets for milling, or insert tip radius сompensation for turning).

Each tool number has its own compensation table; you can also use a compensation number that differs from the tool number. If you have two tools, a roughing tool and a finishing tool, you should use different compensation numbers for each of them.

OK, disconnected the 7i77 from the 6i25. ran mesaflash, linux couldn't find the board.
 

Am I needing a new 6i25? I ordered this AM on the hunch I probably would...



In other news, if I launch linuxCNC with the 7i77 removed from the 6i25, my PC doesnt hard crash anymore, just gives the following error:  

I have the report from that if it means anything. 
All of the above was done on a new (different) PCIe slot...so the slot being a problem should be removed as a potential issue

Disconnect the 7i77 from 6i25, check if MesaFlash finds it.

will provide tomorrow when I am back at the machine.

 

lspci did find the card but mesaflash does not, that may indicate a bad 6I25

There are no LEDs illuminated on a 6I25 in normal use except very briefly at power on.
 

and some more cross-generation mating... the MDS-E-V2 drive (2024) happily talking to the MDS-A-CR (1995) power supply without any persuation...
