heres a pic of the heat sink I have my drives mounted on.
Its 4" wide  x  16" long  with 3- 12v fans.   I believe in keeping electronics cool.
theres a total of 7 fans in my enclosure. this includes the ones in the power supplys.
Hope it all works. MORE LATER.   Questions ,  that is.

  Hood, Chip, Comet,

After a little surfing on some other forums I found this info. This helps to clear up my e-stop questions.

Cutting the power between the capacitor and the Gecko stepper controllers was something that I
suggested a little while ago; however, it is NOT a good idea. Although it would immediately stop the
stepper motors, it would also cause extremely high currents to flow through the Gecko (several hundred
amps). Doing that repeatedly would destroy the Gecko stepper controllers.
 

Mariss suggest cutting the power to the break-out board or opening the circuit that
provides step pulses to the Gecko. Opening the circuit that provides step pulses would require having a
contactor or other circuitry with at least four circuits.
Thanks Guys.
This forum Rocks

  This is off Gecko instructions

    "STEP 2: POWER SUPPLY HOOK-UP
    CAUTION! Never put a switch on the DC side of the power supply! This will damage, if not destroy, your drive!"

  So, whats the best way to e-stop ? I want my e-stop to kill all servo and spindle power.

Hi Comet,
Exactly, my thoughts, but according to Gecko instructions, not to switch dc power to drives.
Don't know why, but thats where e-stop is on my other machine.
Thanks for your input, I need all I can get.

Hood, Chip

Will do - right till the end.
 I just did the test points on the X and got my volt readings just like the instruction say.
Sometimes you just have to walk away and take a break [for a few days] 

My last machine took over a year to complete.  Monday I have a job coming in. A 38 ford pickup street rod.
Wants a tilt front end. Thats the kind of stuff I do.

Later Guys.
Thanks again
I will be back.
