(Solved) Initialization code for a rintelligent ECT60 fails when run on an ECR60

Category: Driver Boards

I don't know the syntax for writing a line of code that causes a factory reset.

I'll try downloading the XAE code and print out the config file to see if there's anything different.

I'll also try "ethercat rescan", thanks.

Just to prolong the drama a bit, the Amazon seller of the ECT60 drive reported that a week-long national holiday is coming up, so they won't be able to ship the drivers until they return - and cancelled my order. Perhaps this is the universe telling me to keep working on the ECR drivers...

When you say to try TwinCAT, do you mean hook it up on a windows system?

If I were to just get a different drive to make this easier for me, which lineup of drives would you recommend, so that I run into as few problems like this with lcec?

Wrapped Rotary on Non Rotary Axis Letter.

Category: Basic Configuration

Hmm...

There must be a solution so your setup can be XYZABC.

How does the PC communicate with the machine?

I use a Mesa 7i76eu with ethernet.  I'm guessing with a little trial and error I could modify the kinematics file to just set the B axis value to a constant 0 to avoid it being in the calculations for TCP and then passthrough the actual value to my joint.  The actual matrix math stuff is well beyond my level, so I'd rather leave that alone.  Not totally sure I'd want to label it B axis instead of W anyway, since B wraps around Y in my head.

I'm going to work a bit on trying to get the axis to retain position values when it's in spindle mode, I'm using a step/dir servo, so I need to figure out a way to keep track of position somehow.

Posible but not simple,
1. Linuxcnc control robot arm - Yes
2. Hand teach - No, you have to build it by force/torque sensor or dynamic model
2. Linuxcnc logging it's trajectory - Yes but linuxcnc trajectory planner only support 3 axis-XYZ readahead. This mean if you record 6 axis and playback it will be very slow

Sync Problem LinuxCNC + EL8EC400F

Category: EtherCAT

Good to hear. Especially the -10 thing.
The "-" actually synchronizes linuxCNC's servo-thread to the DC reference clock.
Wasn't documented, I ran across it in the source code. Seems to work though, and I am happy to get
that feedback from you.
But I don't want to spread this. I have submitted a Pull Request to the linuxcnc-ethercat that will introduce
an option
syncToRefClock="true|false"
that will both document this and 
make it clear that this can be used. Until then, keep using the "-".

hey hakan
i discovered that i had huge latency problem i solved it with disable some features in BIOS and made core isolation, and then i changed the refclock to -10 and it worked! but i want to understand why it worked with -10
thank you guys for your help!

Comment out this line in the ini file.
#HALFILE = LIB:basic_sim.tcl
Hope it doesn't mean a lot of extra errors but I think it might work.
Then give cia402.0.pos-cmd a value in halshow.

Good day Forum
Wondering on possibility of implementing linuxcnc on a Older Motoman robot. 
Wondering if the necessary is in place to be able to to hand teach of the robot arm ( cobot style ) logging its trajectory etc. 
I think that would catapult Linuxcnc in the cobot world. 
ideas?

Thank  you

hm2/hm2_7i76e.0: error finishing read! iter=1342204

Category: Deutsch

Hallo zusammen.Nachdem ich ein paar Erfahrungen mit einem ArduinoUno und ESTLCAM gesammelt habe, versuche ich mich jetzt an LinuxCNC und einer MESA 7i76eu. Mit Windows kenne ich mich recht gut aus. Mit Linux leider noch gar nicht, darum bitte ich um Nachsicht!Mein System besteht zur Zeit aus einem i3 mit 4GB RAM und zwei Realtek LAN-Adapter (einer OnBoard, einer als PCIe-Karte); Debian 12 und LinuxCNC 2.9.4.=11.0ptWie bereits an anderer Stelle hier im Forum beschrieben erhalte ich nach einiger Zeit folgende Fehlermeldung: „hm2/hm2_7i76e.0: error finishing read! iter=1342204„

Wie in diesem Thread ( Mesa i76e error finishing read. Another Time with LinuxCNC 2.9.1 ) beschrieben, habe ich ethtool installiert.Das Auslesen der Werte mit „sudo ethtool –c enp1s0“ zeigt, das „rx-usecs“ bereits auf 0 gesetzt ist.
Soweit ich den Thread richtig gelesen habe, sollte diese Einstellung (bis zu eine reboot) die Fehlermeldung unterdrücken/beseitigen.
Auch habe ich in der Maschinen-INI den Parameter „SERVO-PERIOD“ auf 2000000 gesetzt.Vielleicht hat ja jemand eine Idee, woran es liegt, dass dieser Fehler geschmissen wird. =11.0ptDanke im Voraus und Grüße vom tinker.

I added them back in and got the same error : HAL: ERROR: function 'motion-command-handler' may only be added to one thread

I think the simple minimal sim config I use as a starting point probably has those somewhere so it's complaining about duplicates

You need those two motion-command controller statements, they should go in between the cia402.read-all and write-all as in the example file.
It won't move without those.

It was just an example to show how it is normally done.
You can set the pos-cmd in halshow, try that.
The two drives are distinguished by the variable name srv-2-var srv-1-var etc.

The last item in the list about the motion-command-handler suggests that this is duplicating another one in the standard config.

@Hakan - Any further suggestions? Am I doing something dumb like omitting some essential pin definition, or ir is possible that the cia402 mappings are somehow not working for a dual-stepper drive for some reason?

@scottlaird  - do you have a simple hal file that works for a 2CS3E-D507 and actually gets both closed-loop steppers to move? Ideally in pp mode if possible, but at a push CSP would also work with the risk of more complexity, which is not needed for a toolchanger.

It's the Twincat XAE to download.
You also tried to reset to factory defaults?
Also doing "ethercat rescan" won't hurt, might help.
