Hello everybody. This one is really baffling me. I'm doing the simplest job in the world - facing off my baseplate. I know there is a lot of talk about EMC and limitswitches, however i find it hard to believe it would happen twice in exactly the same spot. All the limit switch inputs reads as off. ANY suggestions on directions to look in would be greatly appreciated. The console says as follows: |

I‘m not a „Pro“ in this case, but I had also some strange Problems with the Endstops. Also then you have the possibility to check which „Endstop“ makes the problems (Command $LIM and there is also another one I don‘t know in the moment) Maybe this could help. |

You will need to modify several files:

This is correct - this repository has been updated as well, and will be kept up to date for some time. New test (or edge) branches will be added at the new home when necessary. If using git or Github desktop to download from the new home dependencies will be pulled in automatically for the selected processor - there is no need to download the core and plugins separately. If not using either of these methods it is easier to download from this repository. Documentation for the new home needs attention - on my todo list... |

Ok - I got things configured again. Now probing and homing works. Next up will be rerunning the job, but unfortunately i've run out of time now. hopefuilly tomorrow evening i can rerun, and see if it halts in the same spot. |

When you update the Sender Version, you can copy the files "App.config" and "Probing.xml" to the new version and then you have all your macros, settings and probing profiles. Also it's a good point to save the $-settings. |

Ok. This is getting more hairy. I've run the same program 4 times now. I got 3 alarm 1's. i picked up my little scope and started measuring. - I discovered the following: Secondly i tried looking at my limit switches when "normal" - not engaged. which was not pretty in my opinion. When engaged it looked like this - ok i think: Bigger was my surprise when i looked at my provbe fixture: I also tried running my spindle at different rpm's while measuring the 5v line and the limit switches, but saw no difference. Now i'm keen to hear if anyone has any bright suggestions on what to do? |

Are the hard limits alarms still occurring in exactly the same place? Have you tried running the GCode program with the spindle turned off (and Z raised up so it does not dig in)? Also, were you able to do a $LIM after the limit hits? Important to know the offending switch. |

@terjeio, I was able to do some tests with the change in usbd_conf.c this afternoon. I can report that three runs of my test milling programme were completed without error. No stalling or stopping of the programme. Will then do the same tests on the machine itself next.
However, as I wrote above, you can get around this by, in my case, manually homing the A-axis $HA. |

@S2000Stefan It is strange that the running time increases, I will look into that soon. |

Is it fair to close this thread and move it to the new discussion #275 ? |

I think so, this has become rather messy and hard to follow. However, I would like you to compile the latest version yourself to see if the issue resurfaces. If it does open a new issue, not a discussion - preferably at the new repository. |

If the problem persists, could you take a lot of pictures of your electronics set up. Might not reveal anything but worth a chance. Also, you should review your grounding situation. I had one customer that was getting resets from the VFD. Earth grounding it made the problem go away. |

It seems to be working flawlessly with the old version of grbl-hal. so something in the new version is not working right. |

Hello Phil,
Grounding could be interesting. I have a proper Ground from the Wall, That
i run through all the psu-grounds. Would you recommend any kind of
grounding of the breakout board as well?
The ground is separate from the dc - on the power supplies.

Are there anyone running on the latest master of grblhal successfully? - it'd be interesting to hear what configurations you're using. perhaps that could help narrow down where it goes wrong? |

I‘m not a „Pro“ in this case, but I had also some strange Problems with the Endstops.
For me it seems, that you have an older „Master“ Version installed, after I installed the „Test“ Branch a few days ago, everything works fine again.
Also then you have the possibility to check which „Endstop“ makes the problems (Command $LIM and there is also another one I don‘t know in the moment)
Maybe this could help.
