@my1987toyota,
How is the recovery going?

If any analog output is not close to 0V at power up, (and no output mis-connections)
there is a hardware problem (perhaps a damaged op-amp) on the card and it needs repair.

more notches are better but how can i set encoder
if encoder can only positioned before geartrain ?

Thanks,

Will give it a try tomorrow.

Well with my project I got interested in other things and haven't spent much time on it in a while.
Partly the placer head desperately needs updating to modern day equipment. Cable and pulley
for the Z axis is in my opinion a terrible idea but the machine was designed in 1993. We have a few
other PnP machines where I work so this one was more or less an experiment. Plus work just
doesn't seem to ease up.

Hello, trying to setup the 7i97T, but output 0 always seems to be at 4.55v no matter what, its enough to power up the board and not connect it to anything. Output 3 is the same. other outputs stay at 0 and do not change through halshow then I enter value manually. Even though they are enabled and scale set. My .ini and .hal files are attached.

Are you sure homing mode 2 is valid? Most drives I have seen are from 17 to 35

ANd also try installing this 6.12 kernel another user built
drive.google.com/drive/folders/16Xlry00L...SlwznPLv?usp=sharing

Please ignore the custom kernel here but follow all other optimisations

There are many new features like energy efficient Ethernet that need setting for best latency

Big pulley count - 60 and 20 for the small one.

The point about the micro steps is messing with me too.

I put everything back together, changed the value to 533, the closest i could get with an integer and it works. It does a full revolution but after 5+ you can see the error propagation. Same behavior with dip switches on default and set to 1600..

is this just something i'm forced to deal with using the PID once i move it to LCNC?

HI Rod,A tester send me this :Debian 10 : jitter max 45200Debian 12:jitter max 29000Debian13:jitter max 522000Ir looks very bad.

I think something is wrong with his setup. He needs to review my Google drive doc to optimise the  performance.I thought I had Debian 13 running here at home but it is on my work computer.But even so,  his Debian 12 latency seems high. Ethercat is installed on this PC 
 

The used kernen in debian 13 :
linux-image-6.12.21-rt-amd64

I havent done the latency myself so far.
For the tester i will make a debian 10 with his current kernel.

But somehow we need a better kernel for debian 13. This looks not usable at all.

Debian 13 does not seem to be using an RT kernel, based on the numbers, but it just might be, i know i had worse on a new PC back in 2020, with RT kernel it would not do anything under 6000000 (yes 6 million).
That was an outlier as i have used over 50 PC and laptop from then, but never that terrible.
I do have a Dell laptop that does that, even with RTAI kernel, if anyone is interested.

The link for the same Page.

I tested all of the public file services offered; some of the alleged URLs were not assigned; a private FTP server or cloud was allegedly tested positive, but no data arrived.

I  just reseted my pc and it worked, weird  . Thanks anyway
