Hello All,

i hope that my question is in the correct corner.
I want to play with home made Component for my hal Files. I have seen en read lots of it. but in te terminal command i can not locate for example the and2.ko file. i can  see the  and.so file. but that is a compiled file i read.

i have the standard debian 12 preemptrt iso installation withe e MESA 7i76E card

i have also update my system to the latest version.  do i have to instal somthing more ?
do someone 1 suggestion.

 

had a home switch come loose and short something now i have a power fail on my 7i76e, think this can be repaired or am i looking at a new board?
 

tied the 24 volt and 5 volt commons together all is well.

Thanks for the help.

jim

no.

jim

Is DIR- connected to 24V common?
 

 


This is the I have the spindle wired.  The relay never activates.

jim

If +12.4V is the open circuit voltage of the  drives direction pin
that would be OK.

 

Field Voltage 24V
TB4 pin3 Spindle + 5V

Dir+ to drive common( Ena- and Dir-)
CW 12.4V
CCW .2V

jim

Can you measure the voltage from DIR+ to drive common in both spindle directions?

DIR- and ENA- are wired to the spindle common.
NC is wired to spindle foward
NO is wired to spindle reverse

jim

What is the Mesa 7i76E Dir- wired to?

Having issues trying to run spindle in reverse.  Using backup 7i76e board never used but new.  I'm using HF41F relay and wired per the Mesa drawing.  The relay has been verified and working.   The Dir+ does not trigger the relay +24 volts applied to the other side of the coil.  Whats the best way to verify Dir+ of the 7i76e is working properly.

Die netzwerk ist niht OK, was ist in die /etc/network/interfaces drin?

so ich hab nun etwas geändert wie es in abschnitt HM-ETH Steht von
www.forum.linuxcnc.org/38-general-linuxc...nnection-lost#226460

mal sehen ob das so klappt ich werde berichten

die frage ist nur, warum musste ich das beim anderen Rechner der hardwaretechnisch voll identisch ist nicht machen

I love these pendants
 
But they take some wiring in.
 
I tried some complex hal trickery to get eveything working but gave up and wrote a custom  component
In addition to that, we are using my Lam stepboost component to get higher performance out of the Lam drivers.
And My Ohmic3 Hypersensing component that uses a THCAD which will be a bug upgrade for Steve.

It was pretty hard to wire up a plasma cutter without a table, so I made a couple of errors to make Steve's job a bit harder.
Shh don't tell anybody but I had to get some hellp to set up  my own ohmic3 component!

I forgot to mention the control box uses a safety relay for the estop circuit. Thats the red relay with the row of lights on it.I elected to utilise an external estop reset button,so we just use the QTplasmac estop as an indicator.

To the left of the safety relay are a couple of force guided relays which add some redundancy to the connection back to linuxcnc that tells us that we are awake! Thse have a plastic pin that forces the relays open to prevent any possibility of the contacts being welded shut. These are the only relays used in the build as the torch is turned on by the 7i76e's onboatd spindle SSR.

So that is a brief summary of the build. Next post will show the after.
