The resistor(s) go in series with the plasma voltage  to the negative THCAD input
Safety wise the resistors should be in the plasma source itself.

Todd , what do the halscope files do ? Are they a test ? All the Bios settings appear to be correct , to allow the Boot from ISO, tried several times with Tommies advice , still no luck.

Thank you for the help guys.  I am still building the computer/cnc.  Wiring the mesa hardware is all that's left.

With that said I am having issues installing Debian 12.  On install I get a bad mirror error.  Once installed sudo apt update gets a few repository errors.  I believe this is all from not being connected to Internet during the install.  Using a USB Wi-Fi dongle that is missing the driver during install, but once booted into Debian 12 is works.  I will try using Ethernet to connect to Internet on the next install.  

With that said, are there any eatx or atx motherboards that work well out of the box with Debian 12?  I am using a dell optiplex 9010 motherboard that I put into an old hypertherm microdedge CNC case.  

Very neat design you have.

What keycaps are you using and how are you doing the symbols / lettering, laser engraving?

Hello I have Raspberry pi 5 and byte 2 bot hat on my mill and it works very fine and now i try to convert it to my lathe with a problem with the spindle speed reading and the index and phase a for cutting thread in the lathe . I have tried to read and understand the Hal mystery with a minor of luck . In Hal Meter i there are a signal at => lowpass.0.in but reading zero at  lowpass.0.out  => abs.0.in pyvcp_options.hal . Can somone helpfull help me with this problem / krister

Hello,
I'm trying to find a simple HAL file to configure Hudson BLDC motors in qhi mode.  I have them running in h mode and qh mode, but I can't seem to get it running in qhi mode.  When I run it in qhi mode, the motor seems to spin only in h mode and doesn't switch to qi mode.  Does anybody have a simplified HAL file test script similar to the ones used in the following link for qhi mode?

Shows 4 configuration options for the ini file that don't limit the spindle rpm in any way, are these for master only?

As the error message indicates:

Is invalid syntax for python 3. Possibly you imported the 'nc_files' folder from an older version of linuxcnc?

You might want to replace your "nc_files/remap_lib" folder with the one available here:

github.com/LinuxCNC/linuxcnc/tree/2.9/nc_files/remap_lib

In the zip file you posted the only "extra" unneeded files I see are all of ones ending in ".halscope". You can safely delete all of those without causing any harm.

As to your issues with booting to live media or reinstalling Linuxcnc. You probably need to turn off those protections in the computer bios, and to do that may require the password to enter the bios editor. If you've forgotten the password, it might be possible to reset this by removing the cmos battery, to return the bios to its default settings.

I've also found the included file browsing/file open ap within Axis to be very limiting to use. The work around we often used was to use the file browser of your choice on your Linux desktop to find the g-code file you want to run, then with a right mouse click use the "axis-remote" command to open to open the g-code file in Axis directly from the file browser. This was especially helpful when wanting to run files saved in network directories that you could not easily find or access using file open in Linuxcnc.

I don't know if this works using other Linuxcnc GUIs or if any of the other GUIs offer an equivalent command to axis-remote that can be used to open a g-code file from another file browser.

I got bad news from the spindle repair shop. They gave me an estimated quote of 8-10k€,,, thats a little bit to much. I think I need do it on my own. 

Need to watch some Robin Renzetti videos to get in the mood to touch that thing

My plan is to replace the bearings on my own and than search for a service provider, that can regrind the taper on the machine. 

Thanks a lot for your replies.

The stahlwerk-plasmacutters look good.
 
I already have a THCAD10 that I use for my hypertherm powermax 1000g3, but the cut quality on the hyptherm is not the best because there is a thermal dynamics-torch mounted on the machine and it doesn't cut without an angle at 10mm steel (2mm bevel to the other side). I already changed most of the parts exept the starter cartrigde, and if I can't get it to work properly I need to buy another plasma-machine. 

So I could change the Plasmacutter and still use the THCAD-10 if I add series resistors.
Maybe you can explain which exact resistor(s) I need and how exactly the resistors should be added to the plasma-cutter ? I
Somewhere I read that the THCAD should not be placed inside the controller-box ? Is that right ? So where should I put the THCAD 10 and the resistors ? 

Thanks

Ich hatte das gleiche Problem und mit sudo dpkg -P raspi-firmware gelöst

Also just realised that when I start with the remap line in the ini file commented out the error still occurs, without the 2 lines after "Python plugin configure() failed, status = -11"

ich danke dir für die bestätigung das mit dem smart serial versteh ich zwar noch nicht wenn man´s aber nur wie du schreibst nur einstellen braucht wird das schon laufen irgendwie

Ein schönes Projekt ist es auf jedenfall und danke für dein angebot mich an dich wenden zu dürfen
