I have some of it, quite old now and I sure didn't pay 20 bucks for it.  
But if the battery is still good I'll give it a shot. I had forgotten 
it.

No easy way to do that.  On one of my machines I have no 
additional encoder counters (3 axes plus spindle encoder)

so I ran it in through the general purpose I/O.

Now, there are a couple other ways to go.  One would be to 
add a PCI (or PCIe) parallel port, set it to input mode
and you get 11 (I think) inputs.  These would be plenty 
adequate for a jog pendant.


Or, if you have enough I/O left, you can do like this :
http://pico-systems.com/pendant.html

There are links to some hal files and schematics that show 
how to do it with minimal I/O by multiplexing the selector
switches.  Using a few diodes, you can cut the I/O pins down 
to seven, and still have 7 selections plus 3 jog rates.
I have XYZ plus feedrate override and spindle override on my 
selector.

Gene,
 I have seen this advertised several times but have never tried it. I saw
the same type of stuff used on my son's knocked out tooth. The dentist
glued it to the adjoining teeth. It lasted in that environment for over a
year.

This is not exactly the same thing but it is close.

[Emc-users] back to my out of whack encoder

2020-02-23 Thread Gene Heskett 
Greetings all;

This is turning into a PITA.

After a weeks cure time I went to remove the blown ATS-667 from that 
pocket in my bracket, using a 1/4" wood chisel and a very small bit of 
alu for a hammer, it came loose so easy I could have just lifted the 
leads by hand.  This was with the pocket scratched up with my pocket 
knife and washed down with brake cleaner before applying the jbfastweld.

Anybody got a foolproof method of making it stick?

Anodize it maybe.

Quick recipe for that?

Then use the slow jbweld to give me time to adjust some 0-80 screws to 
push it around till the quadrature is good. Then ignore it for a week to 
cure...

Cheers, Gene Heskett

OK, I think I understand the mechanics better but still, there is always
the option to write g-code using the machines native coordinates and have
LinuxCNC use the more common "trivial" kinematics that is used with most
milling machines.   Get this to work first even if the goal is to work in
later work in normal units like millimeters x,y,z

[Emc-users] looking to add inputs on Pico setup

2020-02-23 Thread Ed 
Is there an easy way to add encoder inputs on a 4 axis Pico Systems 
setup? Hopefully without giving up I/O.


Specifically adding a hand wheel and to select feed rate and spindle speed.
