Over the holidays, I worked on configuring my Mesa cards and familiarized myself a bit with the Mesa CT. Since I'm not very experienced in writing things off the cuff, I wanted to help you with Mesa CT. However, I only see and recognize my main card, the 7i97t, and the bitfile I loaded is the one for the 797t and 7i74, which is what I want to use via the expansion port. Furthermore, the card combination is to be expanded with a 7i73 for the panel and a 7i84u. Now to my questions: Can I connect the two cards to my 7i74 using a Cat 6 cable, or is it better to run something else through the smart serial port on the card? I've already plugged everything in, and they're getting power; the LEDs light up. But when I use the `halcmd show pin` command, I only see the 7i97t listed. What's going on? How do I proceed, or what do I need to do differently? I've been getting so frustrated with this for days. I did have a small success, though, because I'm hoping to gain a better understanding of the whole thing. I managed to control an LED with a resistor through the 797t, which I was very happy about. But the rest is a complete mystery to me. Thanks, Tom. I look forward to your answers, and please explain the technical terms a bit more simply, as I'm a complete beginner in this area.

If you already have a RealTek card you can try with r8125-dkms or r8168-dkms driver depending on the model.
Often this is will give full network performance. "sudo apt install r8168-dkms"

If you are looking to buy a PC, buy one with an Intel card. You can also buy a PciE Intel card afterwards.

You set micro-stepping in SDO 0x2001:0 which is number of steps per motor revolution.
Then you need to match that in cia402.0.pos-scale which is number of steps per mm/inch.

Hello Experts,

Doubt:01

It is found that using onboard LAN Driver is not at all good for Ethercat Communication.
We would encounter connection drops and other inconsistencies If it is Realtek.

Should I buy a PCIe Network card or Can I use Realtek?

     I am Planning to Replace my Pulse Driver DM556 with Ethercat Stepper Driver ECR86 from Rtelligent.
How is the micro stepping configured ? My setting was 1600 steps per revolution. (Aprox 83.5 Pulse per millimeter)

 

Hallo zusammen und Frohes neues erstmal , ich habe mich über die feiertage an die Konfiguration meiner mesa karten gesetzt und habe mich ein weni mit dem mesa ct vertraut gemacht da ich nicht so wirklich bewandert bin die hal frei schnautze zu schreiben wollte ich mit mit mesa ct weiterhelfen , jedoch ist es so dass ich dort nur meine hauptkarte die 7i97t sehe und erkenne und das bitfile welces ich drauf geladen habe ist das welches für die 797t und 7i74 ist welches ich auch so über den expansion port nutzen möchte desweiteren soll die kombination der karten noch mit einer 7i73 fürs panel und einer 7i84u erweitert werden . Jetzt zu meinen fragen kann ich die beiden karten per cat 6 kabel an meine 7i74 anschließen oder ist es besser da noch was über den smart serial anschluss über die karte laufen zu lassen bzw ich habe das ganze schonmal angesteckt die bekommen auch strom bzw die leds leuchten aber bei dem befehl halcmd show pin sehe ich nur einzig und allein die 7i97t aufgeführt und wie ist das wie geht man da vor oder was muss ich da anders machen ich bin da die tage schon so verzweifelt dran . einen kleinen Erfolg gab es zwar schon da ich mir damit dann ein wenig Verständnis in der ganzen Geschichte verschaffen möchte und zwar hab ich es geschafft eine Led mit einem widerstand zwischen über die 797t anzusteuern da hab ich mich sehr drüber gefreut aber das andere ist mir echt ein Rätsel . Gruß Tom und ich freue mich über die antworten , und bitte die antworten ein wenig einfacher mit beschrieben Fachbegriffen erstellen da ich noch kompletter Neuling in was das angeht .

I've added the following line to hal_input, and it get's me 90% of what I want.

Gesundes neues Jahr 

Ich bekomme es nicht hin kann mir jemand helfen bei der oder Bedingung 
 

Thank you for your help. I will look in to the availability of these cards and then i am going to decide. But the 7i97T looks promising.

Next week i will recive the electrical manual and then I can determin the exact number of I/Os and wich signal they need.

How can I adjust this?
I searched for this because it seems that other users had the same problem.
It was recommended to set the value HOME_ABSOLUTE_ENCODER = 2 and omit HOME_SEARCH_VEL; HOME_LATCH_VEL.
So I set the following.
HOME = 0.0                            
FERROR = 1000                        
MIN_FERROR = 1000            
MAX_VELOCITY = 100            
MAX_ACCELERATION = 750               
MIN_LIMIT = -1800                    
MAX_LIMIT = 100                        
HOME_OFFSET = 0.0
# Sequence for homing Start at 0                     
HOME_SEQUENCE = 0                     
HOME_SEARCH_VEL            = 1     
HOME_LATCH_VEL            = 1     
HOME_IGNORE_LIMITS        = YES
HOME_ABSOLUTE_ENCODER = 2
CIA402_HOMING_ENABLED = 1
CIA402_HOMING_METHOD=4
CIA402_HOMING_SEARCH_VELOCITY=100000
CIA402_HOMING_LATCH_VELOCITY=50000
CIA402_HOMING_ACCELERATION=131072

This now works for at least one axis, but all the others still malfunction.

 

Er87.1 is "One-time excessive position reference increment". It sounds like your drives are trying to move from $home to the last commanded target position in one CSP period.

Try commanding the drive to find home using its CIA402 home method, and immediately (before the homing sequence finishes) set the target position to 0.

Absolutely I would like to try it

I discovered that the bottom right button is disabled by default.
I didn't notice this as I had a 'hidden' modification to enable it.
It was experimental, that is why it is disabled. I could show you how to enable it, if you wish to try it,

PlasmaC 2.8
QtPlasmaC 2.10 or Master.

V2.8 is indeed very reliable but Qtplasmac on 2.8 is not. So many changes since then. In fact there Is a strong case to run 2.10 master branch to get th latest and greatest qtplasmac.

Dear Oliver,
I got my Setup of RPI5,OlimexICE40EVB working in the test-gui.
(3 stepdir plugins, and some bitinputs) These working all in the test gui.
I did the halcompile step. starting linuxcnc with the created ini configuration.
The linuxcnc app cannot be switched on,
it reports USRMOT: ERROR: command timeout.
I'm a linuxcnc newbe so I would appreciate some hints how I could proceed to get linuxcnc running.
Thank you for your time!
regards Robert
