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.

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.

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

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 

you might want to give an indication of where in the world you would be doing business.

Hello friends, I'm new to the group and want to thank you all for your work and for being a helpful, knowledgeable community.
  
I'm interested in what I'm learning and would like to know what career options use this knowledge.  I see some guys mentioning that they've built cnc machines for years - I find that intriguing.  

It sounds like they have their own business; if so, how can I learn about setting up such a business (costs to get started, market in my area, projected income, etc).  I'm considering an engineering or software development degree but this is a career path I'd be interested in following if it continues show good chances of success after careful research.  By "success", I do NOT mean that I require a wealthy income, but 50 hr work weeks for $40k/yr net as an established entrepeneur - that might not be the best success option for me.
Thank you for any insights

You have to compile the component again.

yes, I meant pin numbers as they are shown in the I/O column, but you are right I had a mistake as I tried to configure pwm1, but I experienced the same behavior with pwm0 on i/o pins 7 and 9.
if I use multimeter I see between 2,5..4V signal on pin6 (depends on the value, of course) but nothing on pin8. (corresponding 50pin numbers are 13,17)
/enable signals work properly.
thx

Mesa 7i95T or 7i97T would be all in one, but price might be on the high side for what you need.
You can safely use just a Mesa 7i92T, but must be careful with wiring as the pins are sensitive.
Having said that, i have Mesa 7i92 wired on several of my plasma machines, meaning very high interference environment, and the THCAD is wired with 5-7 meters if cable directly to Mesa 7i92 input, yet i never have issues, ever.
This does imply proper shielding and grounding is a must.
In your case just having good shielded cables and grounding the shield only on the Mesa side inside the box should be fine.

Are you sure you have the pinout correct?

PWM 0 uses 50 pin connector pins 15,19,23

I'm with you, like most of us probably. People like that come and go.

My advice would be:
1. Don't get your blood pressure up, it's not worth it.
2. Only clarify wrong statements that are relevant to the question at hand.
3. Ignore the rest of the babble.

Thanks for your help, that was the problem
