Hello,
Thanks for your interest
I would like to get the opinion of those more knowledgeable than me, I knew it could be done on 7i97 but the price with shipping and customs is high, 7i92 can sometimes be bought from me locally, but I haven't found firmware for 7i92 in this configuration yet, before I make a decision I would like to compare a few options, whether Remora will handle 3 encoders because I think it can with 1, and whether there is another option that I haven't known about yet, I've also read about ethercat but beckhoff modules are even more expensive, best regards

Hallo Hans
die Doku und das Programm findest auf Patreon unter Talla83

See previous post #315502 from November 2024 which has a link where stirra kindly still hosts the files you're looking for.
Note that he cautions you to check with Lichuan support if there are any updated firmware/uploading tools available in case those files should be outdated. Hope this helps!

Hallo Hilton,

hier anschaulicher als Bild:
 

That's actually rather strange behavior and may have to do with
the 7I76E analog output being unsigned.

Can you post your hal/ini files?

I would get open loop working well first with P,I,D == 0
and FF0 = 1, then try to slowly add some P and I

(you will never get good control without FF0)

Also plotting the PID output will help with diagnosis

Sounds promising.
But you mentioned three servos? You need one "kit" with cia402 and lcec for each servo.
So there should be a cia402.2.read-all and one cia402.2.write-all for the third servo as well. And it need to be hooked up to lcec in the same way as the two other servos. Maybe you have that already, it is hard to think the servo works at all without that.

What is the frequency of the oscilllation?

1Hz-ish?

Belts introduce some delay into the system because they stretch a little bit.

You might be able to ameliorate the issue with some sort of smoothing circuit, like the one attached (designed by me).

0V means stopped, correct?

Hallo
Danke für die Nachricht
Ich suche das Doku was Peter (talla83) für die Installierung des Werkzeug Längenmessung erstellt hat, habe in der GITHUB gesucht aber nichts gefunden. Er hat es im seinem Video erwähnt das es eine genaue Beschreibung gibt.
Gruß Hans

Does DIR change in output type 0?

(maybe there's a hardware issue)
 

i changed z steps from 0.05 to 0.1 and it increased speed but it is lower than what i want and what it should be.

There is definitely something wrong in the current source
I went through a bunch of test builds and sserial shows
some random startup issues.

Here's some older source that seems OK

freeby.mesanet.com/7i92t-hm2.zip

Sorry for the problem.

EDIT: found the issue, I built custom firmware for a company which had a hacked vhd file
that I meant to remove but was left in the 7I92t project...
 
You can use the current source by removing wordpr-efx-fpo.vhd from the project and adding
wordpr.vhd


Fixed firmware files:

 

 

 

Also consider CNC repair (like a mechanic), CNC improvement, CNC retail, etc.

It will really depend on where you are, who you are, and wht you already have.

(if you own a big huge truck or van, you can transport machinery in it, for example)

Perhaps refurbishing old machines/reselling scrap machines would be more lucrative.

The world has lots of old machines.

For example, my late great uncle has (had?) an old metal lathe, which could be converted to CNC.

hi dear friends
i have this file.ngc which is used to produce a workpiece in series.
my issue is that speed does not increase . even when i change #4 parameter in file,ngc
i tested g0 and g1 in mdi and machine moves in 4800mm/min speed without any problem but when i run this file.ngc code, speed is limited to 130 roughly
