OK I figured it out almost
The analog pins are PWMs
But if i put this into my HAL:
setp hm2_[MESA](BOARD).0.pwmgen.00.dither true
setp hm2_[MESA](BOARD).0.pwmgen.00.output-type 1 #PWM pin0
setp hm2_[MESA](BOARD).0.pwmgen.00.offset-mode 1 # offset mode so 50% = 0
setp hm2_[MESA](BOARD).0.pwmgen.00.scale 10
setp hm2_[MESA](BOARD).0.pwmgen.00.value 1.0
I get 4.2 volt
Why? I have just double-checked 10/1 = 1

Using the index as home in hal is not what I meant, LinuxCNC does support homing to index:

linuxcnc.org/docs/html/config/ini-homing.html#_configuration

See homing type = index only
 

Thank you for your response.

I forgot to mention that before installing it on LinuxCNC, I tested it with a potentiometer powered by an external 10V source and a 3-position switch for enable and rev, and it worked fine. The problem arises when I try to connect it to the Bob and LinuxCNC. I'm using the Probe Basic interface, but I've also tried it with Axis and the same thing happens.

 

 

7I97 analog outputs are generated from PWM
which requires some setup:


 ---PWM Generator signals/setup---
setp hm2_7i97.0.pwmgen.pwm_frequency 75000
setp  hm2_7i97.0.pwmgen.00.output-type 1 #PWM pin0
setp  hm2_7i97.0.pwmgen.00.offset-mode 1 # offset mode so 50% = 0
setp  hm2_7i97.0.pwmgen.00.scale  10
setp hm2_7i97.0.pwmgen.00.enable true

setp hm2_7i97.0.pwmgen.00.value 1.0


 

I don’t know that specific driver, but what I would try is separating the drive from LinuxCNC first.
There is probably a manual mode to turn the drive by using the front panel on the drive itself.
After that, you can set the needed inputs directly (wired to your DC sources) and use a low voltage (AA battery or similar) to give the analog input directly.
Then, if that works but still not in CNC control, you at least know that LinuxCNC is actually the problem.

you have no tool length to draw the tool stored in your tool table. vtk draws an actual tool to display not a cone. the cone represents a point when no tool is loaded when tool is loaded the stored diameter and length draws the tool. try adding a tool length and you will see the tool.

I've been trying for several days to configure the T3D-L20A-RABF servo motor as a spindle in speed mode, but I can't get it to work.

I've set the parameters p004=1, p047 to auto-zero, p050=1 for 0-10V unipolar, and p103=9 to reverse the spindle. I've set p025=0 (default) to use the analog input AS+.

I'm using pin 17 to control the relay and connecting S0 or 0V/GND to the relay.

I'm using pin 16 to reverse the spindle direction.

And pin 1 is for PWM. I've connected AGND and AS+ to the bobbin's 0-10V pin.

The board is powered by 24V, and the servo driver is also powered by 24V.

When I input the command M3 S100, for example, the spindle energizes and has torque, but it doesn't rotate or respond to RPMs.

With my limited knowledge, I don't know what else to try. T_T

but did you try to go to op-enabled without the cia402 component?

 

That echos my thoughts, I considered throwing that idea out there but decided I'm too much of a newby in this ethercat business to be making too much noise here without trying stuff out on hardware first.

My drive and motors are expected to show up today. Not that that makes it a rush to get this figured out. I still need to decide what I'll build with it once it's working. 

I've finally managed to configure my 7i97t with the mesaCT.
In order to test my card I tried to put a small voltage on the output pin of the analog 0.
I would have expected to be able to use something like
setp hm2_7i97.0.analogout0 1.0
but it seems that the parameter for the analog drives doesnt exist at all?
My firmware is 7i97_d.bin
Where did i get lost this time?

Hi, 
I am reading all the topics on EtherCAT and CIA402 carefully. Unfortunately, I am not a programmer and cannot contribute much.
But I found this page, maybe it will help?
EtherCAT Slave: CiA 402 example  

Note: would it be possible to incorporate certain safety routines? For example, a watchdog if the servo receives the command for homing but does not start moving.

Hello dear administrators,

I would like to raise a concern about the stability and structure of the forum, as it is becoming increasingly difficult to be active here. Often, the forum is unavailable or you can no longer reply to your own posts. Unfortunately, this is very frustrating and a shame, as the forum is an important point of contact for many of us.

Question for our administrator, BigJohnT:

You recently made some adjustments to the server structure. A question about this:

Would it be possible to share a new database, i.e., create a new table in the database?

Is it possible to create a new folder in the root directory where a new Joomla 6.x can be installed?

I would like to implement this suggestion in collaboration with other interested members of the forum.

Specific suggestion for improvement:

A) Installation of a new Joomla 6.x

Installation of the Kanuna forum for Joomla

C) Preparation so that other areas can also be migrated or integrated if desired, such as:

* Downloads
* Search
* Documents
* Archives
* Community
* Forum (this could then be given a new location)
* Wiki
* Source

This is, of course, only a suggestion and not a mandatory requirement! I am not very familiar with Joomla (I only have a small static page with it), but I am convinced that a fresh installation of Joomla and a new forum would improve stability and user-friendliness.

Important:
I am not aiming to migrate the existing forum! Users would have to re-register in the new forum. However, a transition process could be created in which existing members receive an email with a password that they can change when they log in for the first time.

Additional help:
If anyone in the forum is more familiar with Joomla or server structures and is willing to help, please respond with the words: “I offer my help!” Perhaps we can work together to come up with a stable solution.

I hope this suggestion is met with understanding and look forward to your feedback!

Best regards,
Mücke

Hi,
so in the last weeks it is really hard to convince myself to even go to the shop — “badly isolated to small of a heater,” you know how it is. Anyway, I still have a bit of an update.

I worked mainly on the control cabinet and its mounting. In the attachments you can see the box made from laser-cut and pre-bent steel plate, and the arm to mount the cabinet.
I decided to take it in the front of the machine. I reused the foot of the holder that mounted the original one in the back. Because the cabinet now is in the way of the tailstock, it had to be articulated twice. Simple rotation would not have worked.
It’s not quite together yet, but you may still see how it is supposed to go together.
It will be some weeks until I will be able to paint it (again, it is too cold).

I think that’s it for now.

Can't you just forget about cia for the moment and only work with lcec, like I did.
And transition manually 6,7 15.

I've attached my unfinished comp and hal for good luck. also had a look at Dominic's results and its the same
