There's nice background material on electoplating, electrodeposition,
and such in the Wikipedia. I did enough electroplating in grad school
not to want to go there if I can avoid it.
Did you notice that CoolAmp also markets Conducto-Lube? I don't know if
it would work in your

Gene,
I have a gold ring with my call letters K2EMR that I got as a present from

If it weighs about an ounce, Ken, and cost only $16, that would have been

Gentlemen,
While reading the config files for the Mazak I saw the section
where you set up the spindle to 'wrap'. I would like to see that same
capability for the rotary axes.
The C axis on the 5axis sim would work good with the 'wrap'
function. This would work good on a machine I have.
Hi All
I Previously had emc installed via the BDI I have recently tried to
upgrade to emc2,2 . I downloaded the ISO and cut it to a disc
seemingly without a hiccup. I can boot my machine using the live cd
however when I try to install the software the installation hangs at
step 3

It sure looks like a unipolar drive to me. They are probably doing
half-stepping, which would give you the counts per inch that you think
you have.
Power is applied to the two center taps, thru two of the transistors

While it's out I'd meter those 220? ohm carbon composition resistors
surrounded by discolored circuit board. Heat is their enemy and
causes their values to drift
My HobbyCNC board says it is a Unipolar Chopper Control
It does 1/2, 1/4, 1/8, 1/16 microstepping. Uses 6 wire (2 common)

Thanks Curtis. Thats looks close. Too bad it has a 3 Amp max. I need
around 8 Amps with slightly

Ah! Yes. Stopped to think and forgot to start again.
