Find or borrow a used PC.

the pc only reboots when i try to run my configuration. i can run Sample configurations like "axis". But when i try to run the config i created using pncconf wizard the pc just reboots. i also does this if i try to Open Loop test or test / tune axis.

langdons as these are release candidates I would prefer if these are only available from the links on my github page. If you have any images with rcX in the file name on your server could you please kindly remove them.

No, not really, you will need another PC at least.
Lets clear something up first, does the PC reboot when turning ON the Mesa cards, or, when running LinuxCNC ?

@Spumco,
Thank you for reminding me, now i know why i can not recall what was going on as i am used to ignoring everything having to do with clearpath since back when they were selling stepper motors and labeling them as "revolutionary servo motors" for a lot more $, and i think they still do, but now with encoder feedback.

Thank You for that looks like the .hal file is correct now I am assuming I dont have correct settings in the motors thought it would fault if power/loss of com .

or am I missing a config for that? 

Thanks
 

This is why I suggested the FIRST thing was to verify/edit the motor programming using the Clearpath software.

You cannot successfully edit/adjust HAL unless you know exactly what the motor(s) HLFB output is doing under various conditions.

Power up the motors - no need to enable in LCNC - connect a Windows computer to the motors and open the Clearpath software.  Verify that all motors' HLFB output is set to 'Servo On.'

Check your LCNC input pins are working correctly.  You can enable/disable the motors using the Clearpath software (overriding LCNC's output). 

While you enable/disable the motors via Clearpath software, two things should happen:

• The Clearpath software display should show 'servo on' in the output monitor
• LCNC halshow input pins should be high/yellow when enable is true, and low/dark when the motor is not enabled

 


@tommylight - Clearpath motors have no separate drives.  The motors are supplied with DC power and all programming/control stuff is mounted internally in the motor itself.  They have three inputs (enable + A + , and a single output (HLFB) that can be programmed to do different things.

some little progress made, I managed to flash the EEPROM, the name of the device changed and I don't see the input/output anymore.
However, I m not able to pass the INIT step

OK thank you i wil ltry

is there anything else i can test in software / firmware / drivers?

That is most certainly a PC issue, not Mesa/LinuxCNC issue, so the first thing to try is insert the 6i25 into another PCI-E slot, even the long 16X one will work, and so will 8X and 4X ones.

I guess it is not obvious what to do, and one needs a drive with EoE to test with as well.
I looked around a bit and it's not so common with EoE in the drive especially the cheap ones
don't have it. 
I did find an opening though, it's in the SOEM and SOES ethercat master and slave libraries I use for embedded things.
They actually support EoE both master and slave.
I have a bit extra time now when I'm waiting for the hip to grow out again and will read up on that and try to understand the steps.
Then it should be possible to adopt this to IgH and lcec. Maybe.

Hello LinuxCNC experts!

I am having a hard time setting up my LinuxCNC configuration. I have a 6i25 and 7i77. I have confirmed 5V to the P1 connector and jumper is in right hand. I have 26V on TB2. All others connector i have removed from the 7i77.

I have installed: linuxcnc_2.9.4 amd64.hybrid iso file. My Jitter is good.
I did not buy the 6i25 and 7i77 as a kit. i tried to load the firmware this way;

sudo mesaflash --device 5i25 --write (my directory)/5i25_7i77x2.bit
sudo mesaflash --device 5i25 --reload
 
i used the files from mesa website. And it seems to flash without problems.

Than i tried to use pnconf. i setup the encoders XYZ and PWM XYZ and the correct scaling.
When i load the program my pc just reboots. I get no errors. I tried to alot of things from these forums but i cant get any sucess.

Best regards Christian

Remove everything except timedelay and fault inputs.

I still have no idea what your issue is, i am replying to your queries as they come.
Such errors should not be triggered when drives are enabled, so that might well be drive issue.

You are welcome!
I have sometimes used AI to research the topics but when AI starts quoting my forum posts I know I am on my own!

I wonder if you raised an issue for lcec if Scott might become motivated to enhance the hal driver?
Its odd its taken so long before the issue was raised......
