Hey bogie6040!
Yes the pots are 5k @ 1/2 watt.
I do believe I found my particular issue. The pots have a "nib" extended from the mounting base to prevent it from rotating when properly secured.
However since I was just temporary mounting these to a "test" panel I did not bother to cut out for the extrusion "nib" on the pot. So I snug down the pot, not real tight but apparently tight enough to have "warped" the pot's base enough to cause a direct short.
At least that is my conclusion... so user error yet again
Also, just for my piece of mind I installed a 30w regulated 1.3A / 24v DIN mounted power-supply [PS5R-C24]. So now my 24v system is regulated, I feel much better about that.
Also for those interested:
I’m finally up on Linux mint 17.3 Mate Desktop. I built from source LinuxCNC and installed Glade 3.8.5
LMDE 2 Gave my processor's GPU hangups and Jessie required a lot more "work" to become a full desktop. Wheezy truthfully was the best suited to run just as a controller for this mill. But you know hobbyist!
The hardware listed in this thread for this build has turned out to be AWESOME! :woohoo: Im around 5-7 in latency and its wicked fast, I would highly recommend this build to anyone wanting a stable platform for LinuxCNC. [comes with paraport too! V2 and up]
