NX CAM was created by alwinjohn

NX CAM

Category: Post Processors

HI, Is there any postprocessors available for using NX CAM for Linux CNC. Or any other postprocessors which I can modify to suite for Linux CNC. 
Kindly help me?

Gmoccapy SCARA EtherCAT drive - joint error

Category: Gmoccapy

 

After I added both of above setting, the issue still happens.

FERROR and MIN_FERROR entries need to be in the [JOINT_n] section not in the [AXIS_l] section:
linuxcnc.org/docs/html/config/ini-config.html

I tried (FERROR; MIN_FERROR) options: (1;0.1) ; (0.1; 0.01) ; (0.01; 0.001)

I would suggest something like (100,100). I presume you are running your drives in position mode and the loop is closed in the drive, if so LinuxCNC really has no part in monitoring following errors at all and setting the values very high will effectively eliminate following error checking in LinuxCNC.

Yes, I think EtherCAT drives handle joint error, but it makes motor shocking so strong & stop suddenly without finishing targeted  position. 

If you get drive faults because of following error then you likely need to lower acceleration/velocity values. Also note that if your SCARA pose is close to a singular point  the kinematic model will likely fail and cause large or even infinite angular velocities which will then cause the drives to fault.

I folllowed your suggestion and now I have a different error:

Hello Aciera,

Before your advice, I did not have FERROR & MIN_FERROR.
After I added both of above setting, the issue still happens.
I tried (FERROR; MIN_FERROR) options: (1;0.1) ; (0.1; 0.01) ; (0.01; 0.001)

Yes, I think EtherCAT drives handle joint error, but it makes motor shocking so strong & stop suddenly without finishing targeted  position.

I attach my INI file for your reference.

Not like that. Don't change anything in this line "rapid = (float(value) / 100) * self.factor"
If you have updated linuxcnc it is possible that it will work.
You should have checked if there is a line "self.factor = 1.0" in the global variables section, as in the screenshot

I guess you could verify by checking the value of the 'orient.0.mode' pin.

Thank you,Aciera. I just followed the pin guide map in the following link wiki.linuxcnc.org/uploads/orient.svg , I dont know if I need to net the orient.mode and spindle.orient-mode,because it 's not mentioned in that link.

Besides the pins you were already watching also have a look at the 'orient' component pins:
linuxcnc.org/docs/html/man/man9/orient.9.html

This should verify if you are getting any useful signal to 'pos-pid.command'

I see that you have not connected 'orient.0.mode' to 'spindle.0.orient-mode'. Not sure if the 'orient' component has a default value for its 'mode'-pin but you may want to make the connection just to be sure.

Note that I know nothing about the EtherCAT side of things at all, including the 'cia402' component.

Success! So I added the missing pdo entry, and the two missing sync managers (with no pdos set) and now everything is working great. Attached my complete config. Working ethercat-conf.xml:

Built my .ui, works in SIM, how do I move it to the machine?

Category: QtPyVCP

The .ui file is related to the handler.py file. You'd better check the official doc linuxcnc.org/docs/stable/html/gui/qtvcp.html  ,
in real enviroment ,you need also adjust your hal and ini file to satisfy the specific machine detail.

I updated linuxcnc, I edited the file as you suggested:

def slider_rapid_changed(self, value):
rapid = (float(value) / 100) * self.factor = 1.0
self.w.lbl_max_rapid.setText("{:4.0f}".format(rapid))

Now the error is as follow:


Traceback (most recent call last):
