Hello Peter.
The cables look fine but I'm gonna try with new cables tomorrow and see if
it works all day long without trouble. The malfunction is erratic and
happens a few times a day, but it's annoying as hell.
Thank you.

I used to fill those anhydrous ammonia tanks for farmers. Ah, the memories of
donning the goggles and thick rubber gloves and holding my breath while trying
to stay up wind. Leaks were uncommon, but... things happen.

Hello to all!
I have a camshaft grinder wich is working with a MESA 5i20 for 8 years more
or less. Never had a problem until recently.
A couple of days ago I had a major failure on the PC (not the power supply)
so I replaced the complete unit to put the machine to work and then repair
the other

7i90 coming Gene, I'm going to run with my in stock Bob's for now I will
use the optoless one for encoder count , and the opto'd one for controls .
I'm using that optiplex 720 we were discussing last month with the real

In that case the finger of blame points squarely at me.

Yes that is true, there is a threshold for what is considered "low
voltage" an when this went into NEC they were thinking about door
bell, telephones and alarm system and heat thermostats.
But you can use high voltage as long as you follow the code. When
solar panels are installed they almost

What I meant was "no fixture" not "better fixture" For example if you
design the room for LED lighting you can design in something like a
crown molding. Then you can runs a LED strip all the aw atone the top
of every wall.

If efficiency is the goal then don't use 12VDC. Go up to 36 or 48
volts at lest. The best systems are like those use in the solar
industry at 400+ volts DC. Power loss in the wire is "I squared R"
so there should be an incentive to reduce I. Doubling the voltage
reduces loss by 4X doubling

There is not a 5i90, perhaps you mean the 7i90HD? With that, you'll need
