Mach4 General Discussion / Re: Mach4 newbie here. I need some help

Hi,
Ethernet M16 board? I don't recall ever hearing of a board of that name being Mach4 capable.

ESS, PMDX various, PoKeys various, CNCDrive some,Vital Systems various, yes, but Ethernet M16 no, never.

Hi,
it does seem unlikely that an earth loop will cause you any issues in a home situation.

If you ever talk to an Audio engineer or a sound technician for a band...ask about earth loops and they will give you chapter
and verse. Don't overlook earth loops they WILLl cause grief and are hard to solve if you don't keep your eyes/mind
open.

Hi,
to have a second earth stake is to have an earth loop...thats pyhsics.

It may be troublesome but then again it may not. My experience is that earth loops can cause control circuit faults
particularly in industrial situations where large machines can produce large magnetic fields and work on earth loops.

Hi
sorry can't understand you, can you get some help with translation?

Hi,
that might work but may also cause problems.

Your household electrical installation will have an earth rod somewhere. If you go and put in another somewhere near your machine an hook it to the frame of the machine
you will have created an earth loop. By earth loop I mean: frame of your machine to new earth rod, through earth to existing earth rod, to the earth conductor of household
wiring, to the socket you have your machine plugged into, to the metalwork of your machine, a loop. Any alternating magnetic field passing through that loop ill induce
a voltage in the loop potentially causing problems.

You are working the strategy that you wish to reduce the sensitivity of your installation from radiated and/or conducted electrical noise, its a worthy strategy and lots of little
things you can do to make it effective.....BUT there is an even better way.....stop the electrical noise from being generated in the first place. If you never turn your
spindle on then you get no interference....not very helpful. Why is your spindle motor so noisy? Is it a DC motor and if so are the brushes in good order? Are the brush
springs providing the require engagement force?. Are they the right brushes, not some that you found and filed down to fit your motor (yes I've done it)? Is there a RF choke
in series with each brush or could you put one there? Is there suppression capacitors on the motor or have they broken off? If they've been replaced have they ben replaced
with ceramic or silver mica caps? It may be as simple as correcting a fault with your spindle motor and all the noise issues recede into the distance.

Hi Azalin,
can't be of much help, I don't use Darwin but rather an ESS so I was just guessing.

Hi Charlie,
if you slip this into the SigLib table in he screen load script:

Code: [Select]

[mc.ISIG_EMERGENCY]=function (state)
    if (state==1) then
        local inst=mc.mcGetInstance()
        mc.mcCntlEStop(inst)
    end
end,
You're done.

Hi,
just had a thought about another question you raised.

On Configure/Mach/General page check the <X-Z> Active plane and then try assigning motors etc.

Hi Uli,
with the Sim(plugin) you can try it for free for as long as you want, unless you have objections other than cost?

Hi,
I suspect that you will find more answers in the Darwin Parallel Port discussion thread on this board.

There has been some discussion here lately about the charge pump in Mach4/Darwin PP and the upshot is that it doesn't work too well,
I understand that most people no longer consider it necessary and don't use it.
