Good, the UNMATCHED datagrams are gone. One more step done.

Nobody needs that xml file, maybe some geek is looking at it. Linuxcnc doesn't use it,
it can read all necessary info from the drive.

So what I look at are the linesInvalid input configuration. It can be several things, but it has to do with the Syncmanagers and the PDOs.
You said you got the files from another post here, do you have a link to it?

When I look in that esi/xml file you attached I see that you use a PDO index of a fixed PDO, and it looks like you don't have the correct pdoentries in there. There are two things you can do.
1. Use a configurable PDO and put in the existing pdoentries in there.
Simply change
<pdo idx="1b01">
to
<pdo idx="1a00">

and switch
<pdo idx="1701">
to
<pdo idx="1600">

2. Put that right pdoentries in the 1b01 and 1701 pdos. Let's try 1. first.

 

I installed the r8125-dkms as my adapter was RTL8125

What else can I try now?
Also, I got this device description file for my drive from the manufacturer. What do I do with this?

 

Thank you Joco!

This works and I'm able to control my plasmacutter. I really like the interface.

I'm now only facing an issue loading g-code. I'm using the plasmac post processor for Sheetcam which outputs .tap files. When I load a file, I get the message “unknown word where unary operation could be”. I just assume, it has something to do with the filte section in my INI-File.

Is it possible, that the preprocessor cannot interpret my .tap. file?

like this?

What version of PathPilot are you running?  

You said you added logging, what did you do exactly?  Where was it crashing?  I assume you running PathPilot in a way that allows you to see the terminal, so you could wrap the offending areas in a try/except and print the exception to the screen when it fails.  

I would not mess with refactoring Tormach's code, that otherwise works.

@CaliusOptimus, check out the ALTAROS Automatic Turret Head:
www.altaros.cz/content/53-automatic-turret-head

CNC4XR7 on YouTube installed one and has a few videos on it.

Thanks for the reply!

Yes, it's inside the mill(TormachUIBase) class. The indentation got messed up when I copied it over, but I can assure you it's correct in the actual code because the function does work 'sometimes'.

The suggestion to keep the code concise is a good idea, but I'm hesitant to trim it down too much as this mirrors the PathPilot reset code. The last thing I'd want is to initialize one of the HAL pins correctly and that would cause even more issues. I'm really not experienced in the CNCs and have been only tinkering on and on off for about 3 years.

I tried a few cuts at 20 amps and got arc ok, but couldn't get any at 10 amps, which is fine, can't imagine needing 10 amps.
I did a fair bit of cutting at 45 amps and I did lose the arc ok signal in the middle of a cut. It was artsy text so I assume the feed was lowered automatically like it does for small holes. It only happened once, so it may be a fluke.

I have plasmac.arc-lost-delay set to .1. Should I try increasing that or is there a better solution?

I sure hope this hypertherms amp setting is more accurate than your china one, since I have no way of measuring actual amps.

Thanks for your responses! I ordered the 7i96S and the 7i84U.

Probably overkill in terms of the amount of I/O, but now I can go hog wild with panel buttons (just kidding).

Now onto picking components for the CNC lathe conversion!

The view setting is not really necessary, as somehow machine zero is centered at startup. So i removed the ini entry. After loading gcode, the desired view can be selected, and then its centered in the preview. So i solved this by finding my workflow

 

So werde ich es machen.
Vielen lieben Dank!

I wish it did print something out. I added a bunch of error logging to print to the system logs and It seems to be crash at different lines (which I find to be odd).

I have the two computers on the same network and I'm hitting those endpoints via HTTP.

Hi guys,
I need to cut some internal oil grooves in the 8 shape figure. It would also help for external grooves but not at this point.
The spindle encoder is hooked up and working correctly. 
If anyone has achieved this, please give me some hints.
Thx!

I would probably add a series resistor so so if you accidentally ground the ALM- output you do not damage the optocoupler

so:

+12V --> 1K resistor --> ALM+
ALM- --> 7I76EU input

Yes, you can use a 7I76U with  a 7I96S  by using 7i96s_7i76d.bin firmware
and connecting the 7I76U to the 7I96S's P1 expansion connector.
