Is your
sync0Shift="0"
???
You should set sync0Shift to 250000 or 500000
sync0Shift to 0 is not correct, as per my understanding of the ethercat DC specifications.

this is my actual running system... i´m quite impressed...
What do you think?

Compaq? So that is roughly 15-20 years old, giving two possible issues:
-an NVIDIA add on graphic card
-one of the Intel 915 graphic cards built in the chipset
The first is easy, just yank out the card and use the onboard graphic...that might be the 915 and has issues with Linux and was fully blacklisted at one point in time.
Still, there are options:
-power on the PC
-hold down the right side SHIFT key till you see the GRUB menu
-press E to enter editing the boot options
-there should be "quiet splash" on one of the lines, add "nomodeset" after the quiet or splash
-press F10 to boot
Does that work?

The last error message (whilst I was sorting out the copying of stuff into the .ini file - not getting any at present) had this:
Traceback File "/usr/lib/python3/dist-packages/qtpyvcp/plugins/notifications.py", in timerEvent error = self.error_channel.poll() ^^^^^^^^^^^^^^^^^^^^^^^^^ linuxcnc.error: Error buffer invalid
... not sure if any relevance.

All secondary pin function channels are numbered 0..N
(the primary function of each pin is GPIO)
So if you have 6 stepgens, they would be numbered 0 to 5.
And if you had 2 PWM generators or encoders they would be numbered 0 to 1.

Replied by PCW on topic Firmware request: 7i96S + 7i89 on P1 with pktuart
There is no software support package for the 7I89,as it is a passive daughtercard.
Here is firmware for a 7I96S with a 7I89 on P1:
PktUART (V3) on the 7I96s and SSerial channel 0 on the 7I89.

Unfortunately, the Jitter/Clunking came back, even though dc-phased is on.

If the Num column indicates channel if the numbers are one digit long, and the pins associated with the 0 channel are for the x-axis, why is the PWM signal for the spindle and associated encoders also on channel 0 in this

Firmware request: 7i96S + 7i89 on P1 with pktuart was created by JohnnyBeluga
Hi everyone,The download link for the 7i89 firmware/support package on the Mesa website appears to be broken, and I couldn’t find any information about a firmware variant that includes pktuart, and I couldn't find one in the 7i96s package. Would it be possible to make a firmware for 7i96S with 7i89 connected on P1, pktuart enabled (for VFD/Modbus use) on the 7i96s ? Thanks a lot,
