Somewhere under all the trash, round to its, forget me nots, and general detritus is a new bench top CNC with a serious upgrade spindle and a 4th, 5th, axis.

as things progress there will be interesting gcode available to the faithful or futile, I don't remember which.

Any questions?

 

[kopcicle]

Here's your quiz

1) What is the function of this device?

b) Low current currency converter.
c) Source of inconsequential multiple guess quiz.
d) Liberal meltdown detector.

2) Where would this be installed in/on a Uniden 29LTD classic?

Now, wasn't that fun?
Maybe I should go back to bad panda jokes.

Are there any good panda jokes?

frequencies frequently frequenting frequency mixes , and a panda ...

A panda walks into a restaurant, sits down and orders a sandwich. After he finishes eating the sandwich, the panda pulls out a gun and shoots the waiter, and then stands up to go. "Hey!" shouts the manager. "Where are you going? You just shot my waiter and you didn't pay for your sandwich!" The...

CB to 10, CB to six, and Motorola MC145XX PLL .

If you know , you know..

So, this is going to take some explanation and imagination.

In the upper left are two ER11 collets, perpendicular to each other, directly attached to Nema17 stepper motors for rotation and ratio.. These are each opposed by additional stepper motors for positioning. The upper pair slide horizontally and the pair to the left slide vertically.

Now all I have to do is get the rotating pair to turn at a specific ratio and, the remaining pair to position.

Seeing as I'm old, a dinosaur, mostly deaf, partially senile and suffering from ED (educational dysfunction) I now have to re-edumacate myself in the fine art of assembly programming or learn IDE for Arduino from square one.

And so it goes....

Things that make you go hummmm...


Yes, those are MRF151G's
