I found lot of messages
"Failed to get reference clock time: Input/output error"
in LinuxCNC Console 
when I set "refClockSyncCycles="-1" to EtherCat Master configuration.

But if I set refClockSyncCycles="1", I could not see such messages.
I attached
refClockSyncCyclesMinus1.linuxcnc.txt (LinuxCNC Console Log)
refClockSyncCyclesMinus1.dmesg.txt (dmesg Log)
when I execute with  "refClockSyncCycles="-1"

And also, for reference, I attached 
refClockSyncCycles1.linuxcnc.txt (LinuxCNC Console Log)
refClockSyncCycles1.dmesg.txt (dmesg Log)
when I execute with  "refClockSyncCycles="1"
 

I would like to share an S-Curve jerk control I have been working on, actually since I made the OP, I think the code is pretty battle tested, but I based it on an old version, and I would like to port the code to something that the community will be happy with, what should my base code be from which to introduce the jerk control? are you guys ok with master? or 2.9.4?

I have a pretty decent S-curve I have been using for sometime, would you be interested in testing it?

something like

The system utilizes three RS485 devices configured in Auto-send mode rather than the standard Query/Response mode to achieve high-speed data transmission. Each device autonomously broadcasts data packets at a 1ms interval. To ensure simultaneous data acquisition and prevent bus contention, right now the solution employs three independent USB-to-RS485 adapters.

I'm looking to move away from USB interfaces due to noise sensitivity and latency concerns at high speeds. I need a more industrial-grade solution that can handle three simultaneous 1ms RS485 streams without data corruption.

Thanks, will give it a try after routing the network line to the new shop, all metal cladding so wifi does not work from the other shop.

I know this is over 4 years ago, but I was doing some housekeeping in the PlasmaC component, and found reference to a post in this thread.

Did you ever make use of the added pins, etc to sort this issue out?

Hello. I have a Mesa7i92TH and I need a pinout for a Chinese board (mach3 interface board) 5Axis Breakout Board. 4 encoders and four axes. Why is there no 7i92t_5abob_encd.bin firmware in Mesa Configuration Tool II (I installed it via the terminal)? Maybe I need different firmware? 7i92t_7i85sx2d.bin, but it's not there either)))
Thank you very much for your help.

Can you post your ini file and preference file if possible?

Hello. I need a breakout board for a Chinese circuit board (Mach3 interface board) 5Axis Breakout Board.

Let me verify how to do that, it should be simple but I want to test first.

With function mdi and command M66E0L0 the button is disabled while running a program and that doesn't affect its initial functionality. But still hoping there is another way to do that.

By error I mean:

What does LinuxCNC report?

Can you post the complete hal file?

I meant it as an error — I’m not sure how to configure it, what I’m doing wrong, and why the AXIS_A code is written incorrectly. please

Axis works fine, QT dragon also works fine. Its just Probe Basic
