T3 ist das Netzteil für das Raspberry Pi. Ist das offizielle also hatte ich gehofft die Qualität ist etwas besser. Die Buskabel sind hochwertige von Lütze mit Siemens Profinet Steckern. Benutzen wir auf der Arbeit auch so.

Unter dem Metallsteg sitzen das Hauptschütz wo 3 Phasen und Neutralleiter dranhängen, ich tippe, dass das Probleme macht. Ist zwar suboptimal mit dem Metallsteg aber solange es funktioniert... Kommt eh ein Deckel drauf.

Mit dem RCD muss ich noch gucken, ich muss eh die Elektroinstallation neumachen da ich in der Werkstatt noch keinen Drehstrom habe. Hoffe wenn ich da einen extra RCD für die Maschine setze ist der Ableitstrom nicht zu hoch. Als ich so getestet habe (einfach temporär in der UV abgegriffen) hat der RCD ausgelöst aber da kamen ja noch ableitströme vom restlichen Haus dazu.

 

So sieht meine Steuerung mit EtherCat aus. Servos von Lichuan über AliExpress und StepperOnline über deren Website gekauft. Nutzen alle das cia402 Profil, lassen sich also identisch ansprechen. Einzig die vid (Vendor ID) und pid (Product ID) sind anders, müssen also in der ethercat-conf.xml angepasst werden. Man kann die Treiber meines Wissens entweder direkt am Gerät einstellen oder über die ethercat-conf.xml mit SDOs. Letzteres habe ich aber noch nicht ausprobiert. 

Als IO nutze ich Beckhoff Module (EL1018, EL1008 und EL2008 sowie Potentialverteilermodule) weil ich das besser finde als die IO Pins der Motortreiber zu nutzen. Brauche eh mehr als die Treiber bieten. 

Als LinuxCNC Rechner und EtherCat Master läuft ein Raspberry Pi5 8GB. Das größte Problem hatte ich mit EMV, EtherCat scheint deutlich anfälliger zu sein als was ich von Profinet auf der Arbeit gewöhnt bin. Deshalb habe ich im mittleren Kanal einen geerdeten Metallsteg eingesetzt, so scheinen die Probleme behoben zu sein. War leider im Platz etwas begrenzt, sonst hätte ich das Schütz -Q1 nicht direkt unter die IO-Module gepackt. 

hi, can this image use traight to gpio too, rp4b board and i made 3,3V to 5V output level converter board use traight gpio output to stepper motor drivers DM556,
and same i build optocouplr board all input opto to gpio can use safety all gpo, not used BOB card or other board, i made diy own in/out gpio to 5V convert board, hope image can use straight all step/dir, enable, signal out to gpio pin. its easy use level converter module can convert 3,3 rpi output to 5V input by stepper driver controller etc, DM556.
same i think can easy use optocoupler module all input gpio pins. 5-24V in to opto and then 3,3V safety to in rpi gpio.

I have also implemented support for MDS-B-SVJ2 Servos via ethernet. That's the first test. X/Y/Z and the spindle are ok (the video only shows X/Y). I will make some other videos within the next weeks. For a test it's connected via USB ethernet adapter to my notebook (I will move it to a raspberry PI within th next days)

Still quite some way to go .. tool changer, lubrication system, chip conveyor and so on. My Meldas M65 controller had issues with the battery 3 times in a row (and we bought them original from Mitsubishi), everytime the settings are gone we would have to drive to Mitsubishi to put the options in... I'm done with that and move the system to LinuxCNC now.

Hi I have difficults to use terminal its a little bit over my competens in linux ,but I change the cordless mouse to a mouse with a cord and after this the program are esier to work with the most off lagging diasapeard and I also changesd the Base period to 150000 and the Servo_period to 1200000 , after that i open up the idex setup file and set it to setp lowpass.0.gain 0.01 .

Its work great two weeks until today when the program freez again , after hard reboot it starts again .
One strange thing is during running a program nothing happens but if I take a coffebreak and the program idle the famos latensy varning came up on the screen . yors sinserly Krister

Hi everyone, i have an industrial cnc plasma table made by CR Electronic on wich the numerical contol has stopped working and i would like to try and retrofit it with linux cnc and QTPlasmaC interface..
it has 3 axis for the usual X,Y,Z movements and then an additional axis named "K" that is basically a slave to the X axis. it is a tray connected to the air extraction/filtration system that travels underneath the table to catch all the sparks and fumes made when cutting.
it has servomotors on all axis with analog/digital drives controlled with  +/-10V

i have a few question that i'd like to ask before getting started with the retrofit:

What board should buy?
since it has the analog drives i think the ideal board for this retrofit would be the the Mesa 7i97T  combined with a THCAD2 for the THC control.
the plasma currently has a proprietary board wich handled the thc control and the Z axis motion. also it has ohmic sensing and torch breakaway detection. the voltage signal comes from the plasma generator wich is a Hypertherm HD3070 and outputs direct plasma voltage to the thc control, so i'll have to put a high voltage resistor prior to the THCAD2 board.

Do i need 1 or 2 THCAD2 board?
i've read multiple topics about retrofits on cnc plasma tables on the forum but can't figure out if i need to get 1 or 2 boards to combine with the 7i97T Board. can the 7i97T take the input from the plasma voltage to control the THC? or do i need to use the THCAD2 board an then connect the frequency output to the 7i97T? also since it has ohmic sensing and torch breakaway detection wich are 2 wires that trigger two different things, when the torch breakaway circuit opens it senses that the torch disconnected from it's magnetic base and for the ohmic sensing it had another wire on wich when the torch touched the metal plate it closed a circuit and sent the signal to the old thc board that the metal plate was found and the zero was set. can the torch breakaway wire and the ohmic sensig wire be connected directly to the 7i97T board or would i need another THCAD2 Board to have these 2 functions?

Z axis motor:
the old cnc control THC board controlled the Z axis motor wich is powered by 24VDC and since i will be removing that board i won't have a driver for that motor to use, i wanted to replace it with a new servomotor and i've seen the "stepperonline" 100w 230Vac servomotor with his dedicated analog drive,  would that be compatible to be controlled by the Mesa 7i97T? i'll add a picture and the manual to that. 

How to wire the analog servo drives to the 7i97T?
i've read multiple times the manual for the 7i97T board but i'm struggling a little bit to wrap my head around how i should connect the motor drives to the I/O board. i have all the wiring diagrams of the machines wich are very detailed so i've been able to locate all the encoder wires plus the +/- 10v signal and 0V. i still have to understand how to connect the drives to the board correcty.. it seems to have a circuit on the X and Y drive wich is 24VDC generated by the drives for the drive enable signal. i'll add pictures at the end of this topic.

Are all of the current motor drivers on the machine compatible with the 7i97T?
the X and Y axis use the same model of motor driver wich is a TDE-Macno DMBL7 i'll add the manual for that at the end of the topic.
the K axis has a Axor industries mini magnum  MM230T 6/12 drive, i'll add pictures of that too.
this is the new Z axis motor and driver that i'm looking to get. Motor: A6M40-100L2A1-M17 Driver: A6M40-100L2B1-M17 i'll attach the manual and a few pictures of this too. 

Is a Raspberry PI5 suitable for the application?
i wanted to make sure before buying one that the Raspberry PI5 is suitable for my application or if it would be better to get a normal pc.

Thank you in advance for the help.

Yes, I'm using 2.9.8 from 2.9.4 iso image,

there is a line.

raspi-firmware: missing /boot/firmware, did you forget to mout it ?
...　z50-raspi-firmware exited with return code 1



I'm not using raspberry pi, but N150 PC

What should I do ?

Can you run LinuxCNC from the terminal and copy/paste the errors reported when that happens?
Usually linuxcnc -l should start last used config.

Hi and so much thanks to the people made all the work with the linuxcnc for raspberry pi 5 ,its a great job.
I have downloaded 4.8.9 and it's a great distro working so fine from beguining and today after a week or two the program stop and freze after 5-10 min. I can still run the stepper from the keyboard and the speedometer on the spindle is i ok and run but the rest of the program stop . the only way to go on is a hard rebot and then it start fine and then the problem starts again . Are there people who can help me in the right direction 
I use the byte2bot board in Lathe config. /krister

Hi, I'm very new to CNC, and I have a Maxnc15CL from around the year 2000 and am using a Raspberry Pi 5 to communicate with it using LinuxCNC. The Pi 5 has a parallel port hat from Byte 2 Bot, and I'm able to control the spindle, detect the limit switches, enable the motor encoder feedback loop, and make the motors make noise when I tell the axis to move. I suspect that the motor timing is off, but im not too sure if when I change the values, if it's getting closer or further away from actually moving. If anyone has any ideas on how to make this work, I would greatly appreciate it, and im leaving my hal file and .ini file below. Thank you 

I haven't been on the Forum for ages but today I noticed that someone asked if I could post my RPi 5 ethernet settings on this thread.

I think they have been posted a few pages back by someone else, nevertheless the following wider context may be helpful.

As an aside, my RPi 5 and Mesa setup has worked perfectly since the ethernet issue (below) was fixed.

================================================================
The following is copied from another thread.
================================================================

I ran my RPi 5 and 7i96s overnight and completed 40 million pings with zero errors.

sudo chrt 99 ping -i .001 10.10.10.10 -c 40000000

At the same time in the background, I ran Latency Histogram and two Glxgears. I have attached photos in case anybody is interested in seeing the results.

I’m not sure what to make of the maximum ping time of just over 10 ms.

It seems that "hardware-irq-coalesce-rx-usecs 0" has fixed the issues I was having (aside from the 10 ms issue) at least on RPi 5 * GB with LinuxCNC 2.9.2.

======================================

What is this "coalesce" thing?

Interrupt coalesce settings ( access.redhat.com/documentation/en-us/re...ing_networking/index )

"By using interrupt coalescing, the system collects network packets and generates a single interrupt for multiple packets. This increases the amount of data sent to the kernel with one hardware interrupt, which reduces the interrupt load, and maximizes the throughput."

=====================================
My /etc/network/interfaces looks like this:
=====================================

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 10.10.10.11
hardware-irq-coalesce-rx-usecs 0

=========================== 

Cam -> Raspberry PI3 -> 7Inch Touchscreen -> TCP -> WIFI -> LinuxCNC
