Thanks Gents for the comments....
Yes, as Mick Martin has so nicely explained, that gadget is a laser pointer.
I am using WINCNC but I would think that Mach3 would be able to accomplish the same.
I simple turn on the laser and position it where I want the XY to be.
Click on the “Set laser XY” button and the center spindle go to that position and sets it as home.
As for the other “special” attachment.
That, my friends, is a Paten Pending, custom designed apparatus, create especially for me by the great minds at MIT.
Using only the finest materials man can fine and with the acumen of the greatest workmanship known...Really ??? ..LOL
Now for the rest of the story....My “normal” setup for my 3 headed machine is a dust boot for each tool.
Yes I made it myself.
But, since this project required the use of 6” long bits, the normal setup would not do.
There are still plenty of clips flying but it does help control the dust.
So just in case anyone here gets the idea of “borrowing” my exclusive paten pending design, be forewarned,,,I will call out the infamous Philadelphia Lawyers to pay you a visit......LOL
This story could be made into a movie.....
