Do you have another PC that you can use to install?
You can put the hard drive from this PC into another PC, install it there, then move it back to this PC.
Usually it works first try, granted it does install on the other PC.
Make sure to disconnect the hard drives on the other PC before all this to prevent accidentally wiping it.

Any more suggestions? I've now wasted another night after work trying to do this.  I've downloaded the iso again and put it on a different stick. Updated bios. Confirmed internet via live.

Do you mean the other way round?

I think that the ISO files install Trixie.

The .deb packages are linking to bookworm.

Hi Greg,

I have a spare THCAD board that was donated to me by a fellow Linuxcnc forum member that I can send to you if you still need it. Its out in my storage unit in Dubbo so it might be a while before I can send it to you.

You can contact me on my email This email address is being protected from spambots. You need JavaScript enabled to view it.

My experience with my industrial CNC plasma table I designed and built is as follows,
 
  • I would not recommend a water table for a machine that is used in heavy plate production as slag build up on the slats causes them to need frequent cleaning.

     
     
    • I tried multiple solutions to remove the top layer of slag but in heavy use it is only temporary.
    • In the end we ended up just replacing the slats every couple of months as the labor cost to remove and clean them far out-weighted the cost of replacement.
    • When I first built the machine, I incorporated slat mounts into the machine frame but as soon as we started using it for heavy production, we found it very hard to remove the slats to clean them. I rebuilt the slat support mounts and built removeable frames the slats mounted into. We would then crane the thee slat sections out with a forklift every other week to clean out the massive about of metal slag.
    • I was lucky enough that a fire hose reel was positioned near the machine to keep the water level topped up, but after I left the company, my replacement foreman experimented with different water level heights and found that for the air pressure of the Hypertherm Powermax 125 we are using, the water does not need to be at the top of the slats to remove the plasma smoke from the air.
    • I built a large under-table custom water storage tank and had it hot dipped galvanized. I found it very crucial to have a water storage tank to drain the water so the slag can be shoveled out. I spent many hours some days shoveling out slag into a large recycling bin and in heavy use the slag is heavier that concrete.
    • My next table will be a down-draft table as I have seen post on the forum showing how a baffle system can be use to reduce the required air flow suction to safety remove the plasma smoke.
    • I brought a refractometer to keep and eye on the plasma water solution concentration, but found that as long as I keep the water level stable and added trace amounts of plasma water table fluid, rust was mostly non-existent 

       


      I hope this helps someone as I learnt everything the hard way multple times.

  Well tommylight  I think the things shortly going in the positive direction was to distract people and hope it would
all die back down so they could return to screwing everyone over again. Really this is what happens when 
governments are run like a business.
   This is also what happens when legal is confused with ethical.

Large FIL cnc machine retrofit. (12 ton larger maching running linuxcnc)

Category: Show Your Stuff

machine progress has been going slowly but steadily

i used it for its first job today

Job for the local drilling rig  large hunk of aluminium 300mm dia and 600mm long ish machined like 90 percent of it away in the big blue cnc lathe

then i used the FIl to machine a curve on the end and finally i used a smaller cnc mill to machine a big slot in it.

all machines run linuxcnc  and they all just work with no issues

the Fil was accurate as with the linear scale.  that's awesome

needed the FIL cnc as my other cnc mills didn't have enough z height.

 

machine worked nicely though it only has a top speed of 1800 rpm.  I am used to 10000 rpm on the standard smaller cnc machines

cheers

just tried all that again, no luck. I did get a new message this time asking if I would like to force UEFI setup. But still failed at grub install.

QtDragon doesn't steer the oword/mdi path searches.
It does a check to see if the oword is path is valid from the info in the INI.
But even if the path isn't valid, it still passes it to linuxcnc's motion controller.

linuxcnc searches in this order:
[DISPLAY] PROGRAM_PREFIX
[RS274]SUBROUTINE_PATH
[RS274]USER_M_PATH

The 'File not open' error is from the motion controller not Qtdragon.
Maybe Qtdragon is polluting the command, but i can't know that without more information - like the debugging code I spoke about above.

As for docs...
What do you suggest I could add to this?:
linuxcnc.org/docs/devel/html/gui/qtdragon.html#sec:bridge

Disable secure boot, enable CMS, try UEFI and/or Legacy.
All in BIOS.
While at it, disable TMP if any.

It is plugged in and at that part of the setup there is no issues. Maybe I will try live and make sure.
