Hi everyone

Category: General LinuxCNC Questions

I bought a used workbee with a mesa 7i96 board and I have never used linux befor, I got linuxcnc loaded on an old laptop and started working on the board, the previous owner lost all his files in a move so iv tried to figure out how he wired it but he can't rember how he did it.  I got to the point were I can jog moters, I am now onto endstops and I'm lost, I used the pnconfig wizard to set each endstop on its own pin(micro switches power to com and pin to nc) the only thing he left hooked up was the estop on pin 0 but it's backwards(pushed in let's me power linuxcnc in axis mode) and the ssr for the water pump(220v vfd, water cooled spindle and pump), some of the wiring he left on the out row i don't understand and iv looked for days to see if I could find any guides he may have used.  If any one here knows this board we'll and has time to help me id really appreciate it.  I know linuxcnc isn't the best choice for a new cnc owner and new to linux(I'm use to marlin for 3d printers) but I'd like to try and make this machine come back to life.  If this is posted in the wrong spot please move it to the right spot(new here)

AC Servo tuning - Joint 0 following error at high velocities was created by abi9624

AC Servo tuning - Joint 0 following error at high velocities

Category: Basic Configuration

Hi,
I am a newbie to Servo tuning. I made a linear guide (Travel length: 500 mm) and attached servo motor to it.

Servo Motor: Inovance MS1H2-10C30CB-A331Z-INT with 23 bit encoderServo
Drive: Inovance SV670P
Mesa card:7i97T

Servo drive is configured in speed mode and controlled through analog voltage - 10V. Followed the Servo tuning guide from this forum and tuned the P, FF1, FF2 values. Tuned with a displacement of 5mm.

This setup works upto 3000 mm/min for both continuous jogging and fixed length. Above 3000 mm/min, i am getting Joint-0 following error during continuous jogging and less error for small lengths and frequent errors for larger lengths.

I doubt whether the tuning is correct or not. Help me to solve this issue.

I have attached servo drive manual, INI file, HAL file and Hal Scope screenshots at 2880 mm/min and 6000 mm/min for both 5mm and 50 mm jogging.

Thanks in advance.

[SOLVED]linuxcnc Latency test ambiguous results

Category: General LinuxCNC Questions

 
 
 
   
I have run various tests with different commands to check the latency but I don't know if I'm doing things correctly:
stress --cpu 4 --io 4 --vm 4 --vm-bytes 1024M --timeout 120s

[code]chrt 99 ping -i .001 10.10.10.10 -c 40000000

with stress I get good results with all the cpus at maximum usage, instead with chrt even if the cpus are not busy I see disastrous latency.
what should I do (kernel parameters, kernel recompilation)? the PC is not good for LinuxCNC?
If I don't use hardware parallel port and use NVEM, does this latency matter for operation?

my hardware:
motherboard: P8H61/USB3 R2.0
CPU: Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz
VGA: VGA compatible controller: NVIDIA Corporation GF119 [GeForce GT 610] (rev a1) (Driver NOUVEAU)
Controller: NVEM V5

Hi, It turns out I had to reset the power on the device every time i tried a different config.
Suddenly it started working.

I also have a 7i95T card and I have a problem with the configuration. I don't understand your procedure at all...
Please write the most detailed procedure for activating the script and attach the script - I would like to use pnconfig on linuxcnc 2.94.

Thank you

Hi, I'm trying to put together some Beckhoff IO module with ethercat.
I followed the examples and instructions i found on this forum but I can't get my EK1100 to go into OP mode.
I know my ethercat setup is good because I managed to get a servo drive working through ethercat.
Here's some outputs:

It appears G10 L2 and G10 L20 assume machine is actually Homed physically, and no amount of data entry can change that.

I don't understand what you are doing. Without homing the machine first there is really no point in setting offsets.

joint 0 following error

Category: General LinuxCNC Questions

Hello everyone,

I have a strange problem with LinuxCNC on a machine that has been configured for a long time and was working perfectly.

Until a few days ago, everything was working fine. Then I modified my Python Touchy GUI file (adding dynamic multi-language translation using `set_label` on some buttons), and from that moment the problem appeared:

> "joint 0 following error" immediately after clicking "Start".

The problem still remains even if I completely delete all the translation modifications (`LABELS` and `on_combo_language_changed`);


Code I had added:

LABELS = {
    "en": {

@cakeslob , I had a look at your hal file again and copied your spindle stuff exactly just changed for my pins etc and it's still the same. So I think that rules out a hal file problem. I don't think it's the vfd because I can change the speed manually by pressing the + and - manually in the  Axis GUI and it responses quick with no dips when changing speeds.

Went back to Axis.
linuxcnc.var has Parameter #5221 = -238.
Ignoring y and z for this description.
Launch Axis, Display is:
- x238,
- G54 x-238.
This shows G54 x correctly as negative, ( whereas Gmoccapy shows G54 x as positive ).

No amount of Touching-Off, G10 L2, G10 L20, etc, by me gets to the final correct values for a job:
- x0,
- G54 x-238.

It appears G10 L2 and G10 L20 assume machine is actually Homed physically, and no amount of data entry can change that.

For jobs, I turn steppers Off, operate the machine controller to the measured table position, then Touch-Off, energize the steppers, and run the job.

Can anyone provide an alternative procedure to set-up the mill ?

John.

Thanks Cakeslob, which board is the H723 being used? This will be a good test to see if we can get PlatformIO working happy with multiple targets. The code will need #ifdef's and compiler defines for each board to select the code changes needed for each H7 variant.

I thought you upgraded your machine to a Hypertherm 45XP or similar.
If that is the case, please use the Arc OK output on your plasma cutter as it will save you issues in the future.
You can get the cable (and the interface) for your plasma cutter from QWS in Brisbane
