Alex, try
nn being the number you want to set. There is also an upload. Sometimes it is better to do it outside of linuxcnc.
Check for SDO index:subindex using $ "ethercat -p 2 sdos"

Max, did you try to claim it with "AliExpress Seller Protection"?

Philip, the manual says it can be done see snippet here
 
You should be able to add PDO 0x60ff to the SyncManager listing in the config, I think.
0x60ff is also in rxpdo 1703,1704,1705 so one of them should work. I guess.

Glad it's all working now.

To change isolcpus you edit /etc/default/grub as root

Something like:

xed admin:///etc/default/grub

 or

sudo xed /etc/default/grub

and then in the grub file change this line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

To something like:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash isolcpus=3 idle=poll"

(3 assuming you have a 4 core CPU)

When you have saved your changes, you run:

sudo update-grub

and then reboot

Also with RealTek MACs it's likely that you will need to replace the normal RealTek
Ethernet driver with the DKMS version (search the forum for DKMS)

One additional step to improve Ethernet latency is to pin the Ethernet interrupt
to the last (real-time) CPU

To get an idea of Ethernet latency, you can run this command:

sudo chrt 99 ping -i .001 -q -c 60000 (card_ip_address)

This will run for 1 minute and then print statistics
 (card_ip_address) is the motions control cards IP address





 

Hello, thank you for everything!!! Everything works, I would never have found the solution without your help. Milko

In pncconf this is set in the "Spindle Motor" page
in the "Range 1 Max RPM" and "Max Output" spinboxes
 

Output of the command
will be a great starting point, maybe it even works right away.

Is this a 16 IN/OUT module? Then set the halType to "bit" for IN and OUT
and it will automatically generate 16 boolean pins. Check in halshow,
navigate to pins, lcec, 0 and so on.

Hello,
To change the speed when using jog, you need to stop the movement and start the movement again. Is there a solution for this? I am using the gmoccapy interface.

Hi, I'm making a robot arm using linuxcnc.
I have a python interface that i'm playing with. I send the robot commands by setting the axis.L.eoffset-counts pins and the robot moves as expected.
I have a function that polls the robot for its position and waits until it reaches the desired position before sending the next point.
The position is read using the python interface 

but every now and then, the robot reaches its position and waits there for another few seconds before the function exits. I realized that the position feedback gets stuck at some value, and my console prints
I also tried reading the position through the halui.axis.L.pos-relative but the same issue happens.
I assume this is because the internal emcStatus buffer doesn't get updated for those 5 seconds of the main loop.

Why does the loop take so long? How can I debug that?
