I put an old working backup of the ini and hal files just in case. Same outcome. The x and y encoders do read fine when moved by hand.

I think the card needs to be installed during the installation.

That way, its kernel module will be loaded during boot-up.

Never trust AI.

It is totally unreliable.

(people are unreliable too, but AI is unpredictably unreliable)

BTW, you can buy a PCIe or PCI parallel port card for very little money.

Why can't the old PC run LinuxCNC?

Did you try older versions of LCNC?

www.linuxcnc.org/iso/ubuntu-10.04-linuxcnc3-i386.iso
www.linuxcnc.org/iso/linuxcnc-2.7.14-wheezy.iso

You can always put a new HDD in an old PC.

However, if you want to control the machine your way, that is also a good option.

It's up to you.

Bitcoin Scam Busted: Hacker Retrieves Funds for Victims

Awesome Job by iBOLT CYBER HACKER!

Incredible efforts of iBolt Cyber Hacker team just blew my mind.n a time when so many people are falling victim to crypto scams with little to no hope of recovery, this story gives people real hope. The way they tracked, identified, and recovered stolen Bitcoin is nothing short of brilliant. It's rare to see this level of ethical hacking and dedication to justice in the crypto space.

Kudos to iBolt for not only exposing the scam but also helping victims get their hard-earned money back. This is exactly the kind of cybersecurity heroism the world needs more of!

If you did not change anything in the hal/ini files, this points to a hardware failure of some kind.

Do the encoders still read the axis position if you move them by hand?

Hot reload/update carousel probe basic was created by GDTH

Hot reload/update carousel probe basic

Category: QtPyVCP

Hi,
I'm wondering if I'm missing something with
probe basic
, or if it's possible to change or add functionality to it.In previous systems using Heidenhain, I could specify which tool is in which pocket. This made it easy to swap out the entire tool carousel. I was hoping I could achieve something similar here—possibly by modifying the
tool.tbl
file.I'm currently building a list of tools as follows:
  • Tools 0–98: Standard tools
  • Tool 99: Probe
  • Tools 101–106: Separate pneumatic spindles
I've tried looking around for something that supports this kind of setup, but haven't found anything that matches what I'm trying to do. Any guidance or suggestions would be appreciated!

Looks great! 
A new component for the logic, even the easiest way.
Btw, I noticed my hex to bin conversion was totally wrong, but you get the point with 7F and 0F.

Would G93 mode (inverse time) be better suited to your needs than the usual G94 units/min?

Hi. Thanks for the help. It works now. It's not finished yet, but it's a good start.
Here are my files, maybe someone will like it. :-)

Using the correct command:

halcmd: loadusr -Wn vfd hy_vfd -d /dev/ttyUSB1 -b 8 -p none -s1 -r 9600 -n vfd

worked.

Just having someone to bounce ideas off helps immensely.
Thank you Hakan

Nope:

lsmod | grep ch341:

usbserial 65536 2 cp210x,ch341
usbcore 348160 9 usbserial,ehci_pci,usbhid,cp210x,mt76_usb,ehci_hcd,ch341,uhci_hcd,mt7921u

looks like both have been loaded properly.

Those two are the most common devices. That should work.
Redo that "sudo dmesg" with the search for serial. Limit to the last say 10 line though,
that should give the port name. I just plugged in a random usb-serial device I had and got this
hakan@server:~$ sudo dmesg | tail -11

You should hopefully get something similar and there is the device name: /dev/ttyUSB0

Both of these devices have drivers listed in:

/usr/lib/modules/6.1.0-23-rt-amd64/kernel/drivers/usb/serial/ch341.ko

and

/usr/lib/modules/6.1.0-23-rt-amd64/kernel/drivers/usb/serial/cp210x.ko

respectfully. Maybe they haven't been loaded? (insmod?)
