I have the DMM's also....  fantastic kit!

problem solved..........external e-switch wiring fault

I had the same problem for months.  I used my limit switches as home switches.  One
day I discovered I had my Y and X axis limit switches crossed at the break out board...
I never noticed it because the limit switches worked.  It was one of those hand to
 the forehead moments!!!

I think it is a limitation with my machine accuracy.  That was done with the spindle
off and just dragging a sharp point across the plastic sheet.

Thanks guy,

Pete,  believe it or not this is the easiest way to learn to fly besides a flight sim.

They are controlled just like the larger outdoor helis but very inexpensive to play with.

Second to that is a flight sim like this.

After that a 450 or 500 size heli.

Here are some tests I did engraving HO scale bricks in plastic sheet.

Hi guys,  

Thought I would share my first real kit made with my small mill and Mach3.

Hey Joe,

The slot in the drawing is only for the camera wire.  Since the wire has a plug
on both ends I could not use a simple hole for the wire.  There is only 1 slot.

All the adjustment is in the eight 6/32" screws that tighten against the flat spots
on the shaft.  That is why the shaft is 3/8" but the hole in the body is 7/16".  The
shaft is supported entirely by the adjustment screws.  Those screws will give you
angle adjustment in the Z axis and  they will give you Y and X movement to center
once you have the Z correct.

I did not cut the flat spots on the first shaft I made but will be adding them.
Start your adjustments with the screws finger tight.  once you are really close
you can start to tighten down with a wrench.

Sure,

Here is the drawing in DWG and DXF

The Camera is a Logitec E1000 and can be found all over ebay for a "buy it now" and free
shipping for about $7.00.

I did not add the flat spots to my 3/8" shaft but I am planning on making another.  I think the
flat spots will greatly improve the accuracy of the adjustments.

Hi guys,

I ordered a cheap Logitec e1000 video camera off ebay for 7.00 shipped and went about
making a holder for it yesterday.

Here is a youtube video of the results.
