• Use ferrites/EMI filters on the lines coming in and out of the VFD - this solved my problem!

I'm happy to hear of your success! image missing /media/kunena/emoticons/smile.png
I want to add a clarification to that one bullet point: EMI filters are very good for the input side of VFDs, but don't try them on the output side unless they are listed for such use. The output side of a VFD produces such a high level of harmonics, a common emi filter will smoke. Ferrites are fine for input and output side.

i did notice you use machine zero as the G54 offset. try setting it off that and run the test.

I think I got it! 
I tried moving the AC lines by the BOB, but that didn't work, probably because I didn't move them far enough. Last night I added a ferrite on the AC lines, and I was able to run the program without failing. This morning I removed the earth ground because it was temporarily through my window, and ran the program again. It did fail. 
When I started building it I had installed an EMI filter on the main power coming in, before the breaker box. I now realize that anything coming in is negligible compared to what the VFD produces. So I moved the filter to the VFD 220v lines. I think that fixed it! I have now run the program three times without fail! (see pic)

Thank you everyone for your help!

For those looking at this later, here is what I learned:

• Interference is a BIG ISSUE
• Separate AC and DC lines as much as possible
• Use shielding on low voltage signal lines (maybe fine without if 24v)
• Use a shielded spindle cable and keep it short! 
• Ground all shielding, but only at one end
• Avoid ground loops - only have one ground connection for each component
• Use ferrites/EMI filters on the lines coming in and out of the VFD - this solved my problem!
• Ferrites may help stop interference - try putting them if other things don't work

Do these things from the beginning! It will save you a huge headache.

Will be happy to get some feedback, thanks

Okay,I did a dumb haha. I got a little too hung up on pncconf not picking up the 7i73. So I started linuxcnc and ran halcmd show pin | grep 7i73 and they're all there. I'm just going to set my pins in my hal file and it should be good to go

Thanks for the quick response. I ran mesaflash --device 7c81 --addr /dev/spidev0.0 --spi --sserial and seems like it's communicating with the 7i73! I'm still not sure why pncconf isn't showing it? Is there some extra hal configuration that I need to do?

Here's the truncated output from the mesaflash command, just to show it is there
...
SSLBP port 0:
SSLBP Version: 1.43
SSLBP Channels: 2
SSLBP Baud Rate: 2500000
sserial device at channel 1: 7I73 (unit 0x130001F9)
SwRevision = 14
HwRevision = 1
NVBaudRate = 2.5Mb
NVUnitNumber = 0x130001F9
NVWatchDogTimeout = 50ms
.....

I could but that is a pretty huge overhead on a old pc. 

Ich würde das mit OR2 ,in der Maschinen hal versuchen

Hi, 
i installed Linuxcnc 2.9.4 , and would like to use Mouse with bluetooth(logitech m350s).
kommand sudo apt update shows that adding this repository is not safe and disabled by default.
WHAT TO DO ?
 

Hi All,

My Maho 400E is still running an old version of Debian, with XFCE, that would have been the live CD back in about 2019. For my videos, I need to install simplescreenrecorder, as pointing a camera at the screen is lame.

I have tried:
sudo apt-add-repository ppa:maarten-baert/simplescreenrecorder
sudo apt update
This fails with "unable to locate simplescreenrecorder."

Please help with this. I seem to forget all linux knowledge the instant whatever I was trying to do gets done
Cheers,
Mark

 

да пожалуйста.
According to my observations, the queue error simply replaced the error  Probe tripped during non-probe move.

Wow, that's a lot to take in.

 

Sorry, I think I made too big a deal about some of this. That is a nice mill you've got. With a few tweaks it'll be fine.

Do the 220v lines going from the breaker box to the VFD also emit interference?

Yes.
Not sure how I overlooked this part of your question previously.
