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.

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?
forum.linuxcnc.org/27-driver-boards/3559...ethernet-mesa-boards

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
