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

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.

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

Just tried on a locally built version of master, seems to kind of work:
 

I demand a recount!

(of the cog teeth on each pulley)

Here's a fool-proof counting method: Mark one cog with a big mark of a Sharpie.

Then, count each cog around the pulley, leaving a little dot with the sharpie each time you count to make sure you don't accidentally count the same one twice.

Use the number of points to determine the ratio.


Why does the number of microsteps not affect anything?
That's totally impossible!

Yes, it is. In lcnc 2.8 i can run it by typing "genserkins" (not halrun) in terminal, but from 2.9 it seperated to ugenserkins.c and no longer work. I'm trying to add base and tool transform for this module.

update.

I took the motor out just to see if i could get it to reliably spin one revolution. With all the dip switches set to default that number is 1600. And i think i just had a brain blast because switching to the 1600 doesn't change it.

Also conveniently 1600 / 3.12 (the pulley ratio) is 533.3333 pretty close to the 540 number,.

I am going to throw it back together and verify.

Changing from F to 0 the output changes. The motor shaft is shaking as it doesnt have enough torque to spin the pulley. This is true until i get to 8. On 8 it comes alive and spins as it has been. The output seems to improve as i move past 8 but i have no data to confirm this.

I have the debug cord but once i get into the menus i have no idea what i am looking for.
