PNCconf 7i92H and 7i76

Have I written something wrong?
Would you like to respond to my statements?
If not, PLEASE let me know, then I don't have to wait any longer

Thank you for your understanding

I think the easiest way to move forward on this is to:

1. Create a configuration with pncconf that's as close to what you need as possible.

2. If there are issues or missing features in the configuration explain what the issues
are specifically and post the current hal/ini files.

 

Thank you very much for your suggestion - in your words, that's more or less what I've been trying to get at since the beginning of this thread.

I'll try to show you one more time what helps me, perhaps simply listed here in full, if the PDF sent above is not meaningful enough?

As a beginner, I can't possibly ask questions if I don't know how to ask them so that you understand me. Unfortunately, this still applies to the next steps. Of course I have learnt something since the start of this thread on 16th April - so I hope I can follow your procedure?

I would like to mention, for example, that I wanted to know from the beginning to what extent the MESA/LinuxCNC combination is a Plug and Play System. 7 weeks of experience in this thread have shown me that it is not a plug and play system.
It is still not clear to me to what extent the software recognises the contacts?

1. in the attachment you can see the files created with PncConf HAL/INI. However, I can only create the files as "close" to my requirements as my knowledge allows. Apart from that, I am very inquisitive!

2. as I have already tried to explain in my posts and tried to show in the latest post with video, this is exactly what you are talking about ...
I have gaps in my knowledge, or rather I can't get any further because I don't know which ones.
to the written down, a link to a video which shows exactly the working sequence below.

When I open the machine with this HAL/INI file:

I start the CNC machine and ...
- sometimes errors
- sometimes no errors
When errors appear ...
- I close the machine
- open the machine again until no more errors appear (the errors are secondary for me at the moment, because I would like to assign the correct features from the pulldown menus of the PncConf to the corresponding contacts of the 7i76)
If no errors appear ...
- I press the emergency stop
- I switch on the machine with a mouse click

Reference runs of the axes for a Cartesian axis display:
I click on reference runs, then follows ...
- Reference run of the Z axis in direction minus, instead of plus
- the reference run until an error appears (I can't get any further)

What do I want to know about the Reference runs?
why doesn't the machine show me the Cartesian axis view after the click before the axes start moving? (motors 1 and 2 before the Y gantry axis)
why does Z move to Z- and not Z+ for the reference run? (the same applies to X and Y if I move them individually)

What I want to know about the settings* in PncConf? *by settings I mean the individual selection options in the pull-down menus
Initial situation:
My current 4 PNP Sensors are limit and reference switches in one (if more sensors are needed I can upgrade later)
- 1x for the X axis
- 2x for the Y axis (1x for regular use 1x as a reserve in case the regular one is defective)

My facts and questions:
- the X and Z axis sensors are recognised and the servos stop at the PNP sensor
- for each axis "both end and reference position" are selected in the pull-down menu (is that correct?)

Where can I change the direction of travel from - to +?
Which features from the pull-down menus do I need for ...

i now hope that this final list is simple and easy to understand? Otherwise I don't know how I could present it differently in this way and hope that you will ask questions if anything is unclear?

As a start have you read about LinuxCNC homing?

The ini file constants listed in that homing document
are settable in pncconf.

www.linuxcnc.org/lucid/docs/html/config/ini-homing.html

Also have you verified home/limit switch operation with halshow?

How a start have you read about LinuxCNC homing?
- Yes I have read and partially understood the German manual 2.9.2 page 100 regarding this topic.
Why are you asking this question?
- How is the question and answer relevant to my main question?

The ini file constants listed in this homing document are adjustable in pncconf.
- Ok, do I have to assume that this is the case on the PcnConf X,Y and Z axis windows? If this is the case, I have not yet been able to test out the main hit and will probably have to go through a lot of trial and error?
- And what next?
- To what extent is the question and answer relevant to my main question?

Also, have you checked home/limit switch operation with halshow?
- Yes, I have. If by your comment you mean whether the PNP switches switch - then I may write to you as mentioned above in my last post that the axles can be moved by hand (not during the reference runs) and the sensors interrupt the run.

I would like to briefly ask/mention my thoughts on a procedure according to which I imagine checking all connections on the 7i76 first? Is this not the case?

Is it absolutely necessary for and with LinuxCNC and with 7i76 and 7i92 that certain steps have to be carried out first so that the next step can be taken at all, or is it possible that all actuators of the machine are first connected to the 7i76, checked and configured.

Why are you asking this question?

Because your initial issue in the video seems to be that the home search
direction was wrong, which indicates you did not set up the homing direction
correctly in pncconf.

and how i do that?

HOME_SEARCH_VEL = -10
 i.e. change the sign in the ini file to -ve or+ve
 

I would first verify that your X,Y,Z directions are correct
(by jogging and watching the motion and position display)

Then you change the sign of the home search velocity if
its wrong
 

It would help if you posted your Hal and ini files
