THANK YOU VERY MUCH

After a little bit testing and understanding i got the output to work

Powering the enable input disables the drive; perhaps that's the problem.

Leave the driver's enable pins unconnected or shorted together.

See if that fixees your problem.

Hello! 

I installed LinuxCNC 2.9.4 on a Dell optiplex 790 PC. I attached a parallel port card to the PCI slot and connected a BOB to it. I attached a single  DM556 driver and a 57BYGH76-8 Nema 23 stepper motor to the X axis following the recommendations for the wiring(attached photos) but the stepper motor is not moving. The motor is powered (it's impossible to turn it by hand when the power supplies are connected). I tried to remove the GPU (Gigabyte NVIDIA GeForce GTX 660) but the stepper is still not working but the OS is running better (before this when I tried to do a Latency Test the OS crashed a several times).
Do you have any suggestions?

Thank you,

Adrian

Thank you!

I got carousel and looked through it quick. 

So my understanding is the machine has a main INI file and HAL file.  The INI file pulls in the HAL files that are to be used.  HAL files connect real world things to hardware, hardware to hardware and anything virtual?


What file actually dictates how the machine moves for carousel, and what language would it be programmed with?  Im an industrial electrician that programs with ladder.

Danke für die weiteren Infos!

Raspi ist da, der Rest im Zulauf.

Die aktuelle .hal und .ini habe ich mal angehängt.

Die Fräse hatte bei Kauf eine interessante Ansteuerung - ein Windows 95 Laptop der per Windows Software (..hab den Namen nicht mehr im Kopf) über eine serielle Leitung einen i386 "Industriecomputer" in einem kleinen PC-Gehäuse, der dann mit einem DOS Programm über die LPT Schnittstelle die Fräse gesteuert hat. Dazwischen hing dann noch eine kleine Schaltung die mit 2 Potis die Spindel steuert.
Da der Laptop schon meine dxf Dateien nicht lesen konnte, war der Umstieg auf was modernes keine schwere Entscheidung.

Aber alles gut genug dokumentiert, so dass ich relativ problemlos das Verbindungskabel zu LinuxCNC basteln konnte.
Die Spindeldrehzahl wird immer noch von der kleinen Platine mit den 2 Potis gesteuert, ein/ausschalten kann ich aber im LinuxCNC.
Im Idealfall gibt das Netzteil der Spindelsteuerung auch 5V aus, dann brauche ich da zumindest nichts weiteres besorgen.

Habe ich das mit der Konfig der mesa Karten richtig verstanden, dass ich zuerst herausfinden muss wieviele Ein- und Ausgänge ich brauche um dann die passende Konfig auf die Karte zu spielen?

In das generelle Setup der mesa Karte habe ich mich etwas eingelesen, eine Netzwerk-Verbindung sollte ich schaffen (..berühmte letzte Worte..)

I got this message 6.1.0-30-rt-amd64
How do i do it?

Then at least part of the problem is with the Realtek network adapter.
There are two things you can try
1. Install the realtek-dkms drivers and use them instead of the default realtek drivers. Search in the forum for info, many people has done that.
2. Install a PCIe Intel network adapter.

@Sigma1912 has posted a way to fix the problem on github but that means to build everything from the sources (www.linuxcnc.org/docs/html/code/building-linuxcnc.html).
If that is not "in your blood" you may have to wait for 2.9.7... I don't know if you could (or should) install my .deb file.
 

I'm updating to Debian 13 and I see it's downloading version 6.12.48 now.
I'm really excited—this issue has been bothering me for nearly half a year, and I hope it gets resolved.

It was just an "apt upgrade", I am using debian trixie on that computer.
It may not be the kernel for you. It may not have been for me either, I messed around with many things that day.
You can always try an "apt update" followed by "apt upgrade". That should install the latest kernel and many more upgraded apps.

The messages you get is what I got using Realtek network interface.
What network interface do you have? Find out with "lspci"

If using a THCAD for ohmic sensing has issues with water. the most likely issue
is that the sense  resistor is too high a value.

I agree and I am pretty sure i mentioned somewhere a long time ago that a lower value resistor should be used for sensing. Something that will result in 20-50mA current should do just fine, maybe more as the water used will get lower resistance the more cuts are done and as it evaporates.

Thanks everyone for the feedback. I’ll keep you posted as things progress.

Thank you for your response!
I'd like to try your method and hope it can resolve my current issue.
I haven't worked on updating the preempt-rt kernel before.
Are there any tutorial posts you could recommend to me?
Also, where can I download the 6.12-48 version you mentioned?

Current Kernel: Linux debian 6.1.0-23-rt-amd64

You can also investigate if it is possible to wire the glass scale directly to the servo drive.
The servo drive will then use the glass scale instead of the servo's encoder.
