Typo!

"desginer" should be "designer", right?


Also, laptops are generally not optimal for LinuxCNC, especially fopr parallel port setups.

INI and HAL files

Category: General LinuxCNC Questions

I feel like I am going to have to modify the files manually, to get the automatic tool changer working, and setting up things like servo drive enable, alarm input, estop, high and low speed on the spindle.

I could be wrong, very new to this.

Upgrade of CNC Plasma Cutting Table with Mesa 7i96S, THCAD-2 And MyOhmic PRO was created by GuessWho

Upgrade of CNC Plasma Cutting Table with Mesa 7i96S, THCAD-2 And MyOhmic PRO

Category: Driver Boards

Hi all and thank you for checking this topic!

Little intro to my project and why I cam here.
I'm here asking for help with upgrading my table. I've bought a CNC plasma cutting table with the hope of starting my own thing and because it looked like a lot of fun. Couple of months down the road it turned out that the table is more on the hobbyist side than I would like. So I decided to start upgrading it in order to have higher quality cuts that I can be proud of.

My current setup.

PLASMA SOURCE
  • Unit: Sherman CNC 130 (CNC variant).
  • Divided arc output: 1:20 divider present on the machine (available for THC feedback).

CONTROL
  • Unknown motion  control board
  • Unknown THC controller
MOTION, DRIVES, AND POWER
  • Motors: stepper-based system in use - Nema 24 - 60bhh86-300e-24db 
  • Stepper drivers: 3 × CW-5045 in use for X, Y1/Y2, Z. (
  • X/Y motion: rack & pinion, 
  • Z motion: drive type ballscrew.
  • Installed Power: 400VA transformer labeled “230V / 12A” and “SMT 400VA”. This is a step-down transformer: it takes the 230VAC mains in and produces about 30VAC (at up to 12A) on the secondary. After a bridge rectifier and filter capacitor, that 30VAC becomes roughly 42VDC.

CONTROL AND SOFTWARE
  • CAM: SheetCam (current workflow).
  • Machine control (current): Mach3.
TABLE
  • 3.5 × 2.0 m with water bed.

My plan.
  • Move to LinuxCNC with QtPlasmaC.
  • Move to Mesa 7i96S: Ethernet motion interface
  • Move to Mesa THCAD-2: for 1:20 arc-voltage THC input
  • Move to MyOhmic PRO
  • Install limit switches
  • Use 18 AWG (0.75mm2) shielded cables for the up to 24V connections
  • Use 16 AWG (1.5mm2) shielded cables for the connections that are more than 24v
In short: to replace the controls, cables, add limit switches and keep the rest

The diagram.
I've reused a diagram from the forum (I believe that it's LOWRIDER3) which turns out to be immense help, I'm not sure I would be able to come up with anything useful if it wasn't for it!

I'm adding the diagram itself so that you good folks can make comments, recommendations, critiques. Thank you all in advance!

Well to be fair there is the included Qtvcp too.
You can build what ever you like with it.
Qtdragon uses Qtvcp.

What toolkit is best is probably subjective :)
 

One of the big differences is Flex GUI uses PyQt6 while all the other PyQt gui's use PyQt5 which is at the end of it's life.

PyQt5 is based on Qt5 which was a cross-platform application framework used for building graphical user interfaces (GUIs) and other programs with C++. It was a major version of the Qt toolkit, but its support ended in May 2025

My Ini already had the POSTGUI_HALFILE = custom_postgui.hal

In my Display Section ii this ->
GLADEVCP= -u ./hitcounter.py /home/cnc/linuxcnc/configs/Fräse/test.ui

BUT i receive the "hitcounter.py" error from my post before

Today i did a Sudo ... update and upgrade. During the upgrade i got these errors. Somewhere there the problem?


Not sure why you keep hacking away at your setup.

Any particular reason for not trying the example.ui I have attached?

You mentioned you should have an Intel driver. In which case the R8168-dkms won't be installed or do anything. Start at the beginning

fixing "raspi firmware" errors on the official amd64 ISO

Category: Installing LinuxCNC

Still even if it was Debian's fault we should have come up with a fix. I'm attempting to use Live-Build on a Debian install and hopefully I wont have the issue with dpkg and grub. Somehow start-stop-daemon was left out whilst building the ISO.

And it does appear the added line to preseed does what it should do when running the installer from the ISO.


Update:
ISO Build completed successfully on my Debian partition.
Quick eval via install on VirtualBox, successful no raspi-firmware installed, Linuxcnc-2.9.6 installed,
Issues: asks for root passwd, my fault will fix on another build, ISO still identifies as 2.9.4, need to update the config file.

Index for known RPi issues& solutions.

forum.linuxcnc.org/38-general-linuxcnc-q...official-images-only

On board Rpi Wifi does work, version of installed Linuxcnc does not matter, if you used the official images.

Any USB Dongle that works with Debian will work as the image is soley based on Debian with Linuxcnc installed and some stuff from the Official RPi github, kernel sources and so on.

Sorry I can only speak English.

It looks to have been recently fixed upstream.

(I am still not clear if you are blaming me, Rod or Roland Clobus)

I blame Debian for not fixing this 12.0 bug in their builder in subsequent releases of Bookworm eg 12.1

Category: Installing LinuxCNC

OK I think I've found a fix for this thing when installing from the ISO. The ISO needs rebuilding, the one built failed during the grub install, this was tracked down to an issue to dpkg install when building the ISO.
So I had to do some messing about, to install grub inside the installed system in my virtual machine. I haven't had chance to fix/find out why I had the issue with the ISO.

A small edit is required to the config/includes.install/preseed.cfg
At the end of the file add this line:
d-i preseed/late_command string in-target apt-get -y purge raspi-firmeware
Obviously a new image ISO will need to be created, for this mod to be included.


Whilst the installer still installs raspi-firmware at the end of the install process the above line removes the package. The live session will still have the raspi-firmware but I really haven't heard of anyone attempting to update the kernel on a live session. Still a bit of a hack, but the system once installed to a HDD\SSD or large storage rock it wont have the raspi-firmware installed.

The ISO issue maybe cos I was using Mint to build the image and had to install live-build from the debian repo & there might have been a mis-match......I dunno
