do the inputs:

hm2_7i96s.0.inm.00.input-00
hm2_7i96s.0.inm.00.input-01

Change when you move the jog wheel?

If not, there may be a wiring error or the MPG A/B outputs don't have enough swing.

Check the high level at the 7I96S inputs. if lower than say 3.5V they may
need a pullup resistor to 5V to get enough swing for the isolated inputs

If the swing is too low, another option is to tie the 7I96S input common to +5V
(but this forces all inputs to be sourcing 5V type)
 

Ok moved mpg gnd to tb3-12, still nothing, im really stumped on this one.

Hooked the scope up while the motor was running. And it's interference that seems to be causing the loss of counting. Pulses look terrible .I'd imagine it's the motor is causing it. I have filters and coils on the AC lines and motor lines from the VFD. The encoder is mounted in a 3D printed mounting so it's not touching the case. When I ground the outer encoder case to a ground it helps a little but not much. Any ideas to mitigate the noise. Should I get another encoder with differential outputs and single end it close to the ec500? Or use the existing encoder and put a differential IC close to the encoder and Rx IC single end close to the ec500?

I have TB3 input common as ground to the 24v power supply and inputs are 24v+ to the individual input temrinals, the mpg is pulling 5v+ power and ground from TB1-1 & 6.  so ground should be common for mpg and normal inputs.  still not working, must be something in my hal?

Yes, the only thing different is the source pin of the counts

having a heck of a time figuring this out, have the axis select working and the increments select working and showing in halshow but cannot get the counts to move.  wired as shown in the example what did i miss?  is there a setting for the 7i96s? jumpers? didn't see anything for mpg in the manual for it, only for the encoder input for spindle.  anyone have a suggestion?  mpg.hal pastebin below:

Thanks in advance!

Moved this to PlasmaC section and had to change the tittle as it is not LinuxCNC issue, but it surely still is an QtPlasmaC issue, apparently.
I am sure i have mentioned this a year or two back, but i can not find it here or on the NAS as to what i changed for it to work. Will try again later, hopefully.

Personally, the e-stop behavior should have not been changed, ever, and no latches.

Hey All,

So new CNC built and i'm trying to connect to it. and thats fine, however I cant get linuxcnc to do anything once open, the estop is stuck on.

hi,

no all cia402 has same homing subroutine call and you will probably have to customize for your driver yourself... I have done it in dominiks component cia402.comp but for my driver it was little bit different and therefore I recall it as ds402.comp because of Kollmorgen standard ... but for inspiration should be goot for you... you can customize your driver which will be workable for your stuff for 100% 

for index homing you have to define them in the SDO startup config probably

regards

 

Question, do anybody know the gear ratio between the screws and servos on a machine with Siemens servos?
The servos are 1ft5 Servos and the pitch of the screws seems to be 12 mm what i could measure with calipers. 

 

Ok, that is what I'm currently using and it works well, I thought maybe it would make more sense to run the VFD through Beckhoff thus all connections to the PC would be EtherCAT. I'll probably continue with USB.
Thanks!

Thank you for your feedback, error operation not permitted fo the rtapi_app_main was probably due to the fact the i returned -1 when the function hal_pin_float_new failed.

to install (compile) it, i simply use the following command :
ricardo@RicardoCNC:~/Desktop/linuxcnc-config/src$ sudo halcompile --install my_handler.c
[sudo] password for ricardo:
Compiling realtime my_handler.c
Linking my_handler.so
cp my_handler.so /usr/lib/linuxcnc/modules/

I could solve this first part of the problem by using the function hal_pin_float_newf.

However, i have a different issue now, i do not exactly now what it did wrong on my config files. I uploaded everything.

Thanks for you valuable help

Hello again,

Solve the first part of the problem. i do not know exactly why but i could not make work hal_pin_float_new but if i used instead  hal_pin_float_newf with a structure it works.

however, i am still seeing some issue as you can see per the annexed screenshot. The emcMotionInit is not able to start. 

Do you have any idea what i am doing wrong ? My goal for not is just to have a component that can output/input the theoretical/real position.

i updated the files and they are annexed.

Thanks in advance for your help

how did you install the my_handler.c file?
From the error report, my_handler has no access rights to rtapi_app_main.

Thanks for you input.
You where correct. Im almost embaressed to tell this.
I turned off the machine and had xmas/new year.

Came back at it was working.
Just needed a good reboot.

But I have a follow up question.
I cant figure out why it gets in to a frenzy when I press stopp.

Must be the driver.
But is there any way to stop this.
in linuxcnc.

What is deadband for

 

Dear LinuxCNC Enthusiasts,

I’m new to LinuxCNC and working on a custom setup. My hardware includes a PCI board (not Mesa or parallel port), which handles real-time interrupts. The drives manage their own position PID loops; they only require the theoretical trajectory, which I provide via a proprietary protocol using a custom library. Feedback data, like actual position, is also available if needed.Since my setup is non-standard, I’ve manually created the necessary INI, HAL, and HAL C files. However, I’m encountering the following errors:   
HAL: ERROR: pin_new(my_handler.0-pos-cmd) called with already-initialized memory
HAL: ERROR: data_ptr_addr not in shared memory
Failed to create x_pos_cmd pin.


I use hal_malloc, and insure proper initialitation, but the errors persist.The 3 files that i use are attached. At this point, i would just need a sample to a component that will simply print out the theoritical possition and sent back this theoritical position as the real position (just for the example)I’d greatly appreciate guidance on debugging or examples of similar setups.

Thanks in advance for your help!
