This has troubled me for awhile. I have the XHC-HB04 pendant. On it is
a "1/2" button. It is very useful when your CNC job uses center datum
and you want to place it in the center of your stock. e.g. you've got a
X=10" wide board, you do X=0 at one side, move to the other size and
X=10, hit

Gentlemen,
I have a 5 axis cutter diameter compensation routine working in my cam
package. I am studying the LinuxCNC docs to figure out where/how to
implement it.
As of now it is not universally applicable. It is meant to work on a
machine with the two axis head

Hello,
I want to try 7i90HD on my Raspberry Pi 2. I think Gene did that recently
with Pi 3, so I digged through the list... but the information is a bit
sparse. Also a lot of outdated info on the net.
Please help me figure it out.
First, I need to get LinuxCNC running:
1. Install a raspbian imag
Wish I'd have known about those 5 years ago, likely would have worked better
than the motors I did settle on.

My point was, browsing ebay for something usable can often be frustrating and
fruitless. Most people (including my self) wouldn't know a thing about that
motor. I googled it for a few minutes before posting my 1st email and was

I felt that I said more than $.02... no inflation, just additional
opinion ;)
I don't want to argue more but will answer some of your questions.
I posted the motor specs, other than the dimensions. I can measure one
for you next time I am in the garage if you like. Brushes are a common

The same model number of servo came with either a 500ppr or 1000ppr
Renco encoder from my research. Unfortunately Renco put the part number
under the cap.
As a note, the previously mentioned CHNC ran at a reduced ~50v for a

Very true Todd. I relied on advice from others who have been there, done
that. I also worked with a CHNC that had some E661 servos so knew about
what their capabilities were. But google helps a bunch too in this
particular case...

The problem with trying to buy used motor like that is how do you know what the
motor specs are. There is nothing posted on the add, the Electrocraft part
numbers are old and obsolete, or are a custom part number so you can't just
look them up (at least not easily). What are the motor dimensio
There are several 'sellers' from NES Sales in New York state. I bought a
total of 6 from two of them doing a make an offer and they both accepted
my offers which ended up at just under $40 each by the time I added
shipping. All 6 appear to be in working order, the brushes have little
wear, and all
Do you have a link to the $40 servo and $50 drive? All I can find on
fleabay is $52 and up for the servo + $26 to $32 for shipping.

Tormach has a pretty good white paper on why they chose to use 3 phase
steppers on their machines. I found it a great read for future reference
even though I was going to use servos anyway.
On another note... you can get E661 servos with encoders off of ebay for

Greetings everybody;
I just spent an hour on wikipedia, and another hour reading everything
that google spits out on 3 phase stepper motors, and have not found a
convincing argument in favor of 2 phase, other than their ready
availability.
