If you want the ultimate setting device, have a look at this.

I use one of these nearly every day.

Laser Centre & Edge Finder with 6mm Dia Shank(Reference #LCEF..)
The Laser Center/Edge Finder ® was introduced by SDA Mfg. at the Visalia, CA "Men, Metal & Machines" show on October 4th 2004.

Designed to replace traditional wigglers and mechanical or electronic edge finders

6mm shank - can be used with the smallest of machines

Precision edge finding without readjusting for radius of edge finding tool

Quickly locate center punch marks or scribe line intersections

Can be used with drill presses, to set mill head angle, realign lathe tailstock after taper cutting, lathes with 4-jaw chuck setup or to align the vice on the mill table.

Product Overview:

The Laser Center/Edge Finder ® is a new tool for your mill that will save setup time. For the new Home Shop Machinist it will eliminate the frustrations and doubts of learning the century old Indirect Method with the conventional Edge Finders or Wiggler.

The Laser Center/Edge Finder ® is a Direct Method center or edge finder. Current Center/Edge Finders are Indirect Methods. Current Finders require the Mill operator to determine where the edge of the material is by imposing sufficient pressure on the finder to just slightly bump the material and then move over one-half the diameter of the edge finder to locate the true edge of the material. Another accepted method is a center/edge finder that has a spring loaded conical disc that kicks sideways when touching the edge of the material and the Mill operator then moves the mill table over one-half the diameter of the edge finder to locate the true edge of the material.

The mechanical/electrical center/edge finders function as the mechanical ones do except that instead of a spring loaded offset disc it utilizes electrical continuity to determine when the edge finder has contacted the material (not always useful on non-conducting material). The Mill operator hears an audible signal or a light comes on indicating contact has been made. The operator must still add half the diameter of the edge finder to determine the true edge of the material.

The Laser Center/Edge Finder ® only requires the Mill operator to move the table under the small Laser beam until the laser light shows that the light is at the edge of the material to locate the true edge of the material. If the Mill operator is attempting to position the Mill quill to a Center Punched mark on the material, the table is moved until the laser light centers on the punched mark. In both instances this Direct Method eliminates the most common mistake of forgetting to add half the diameter of the conventional center/edge finder to locate the true edge of the material.

SHANK DIAMETER: - 6mm

OVERALL DIAMETER:- 20mm

OVERALL LENGTH: 70mm

LASER MODULE: Class IIIa (<5 mW) 640-660nm 4.5v

BEAM SPOT DIAMETER: 0.1mm-0.5mm (Dependent on surface reflectivity)

BATTERIES: LR44 1.5V (3X) (batteries included)

M98 P1001 is a call to a sub program the Pnnnn is the sub program you want to call

The Lnn is the number of times you want to call the sub

M99 is return to the calling program.

This is what I get using the code :-

Make sure you have a CR after the M99 on the last line of code

Try changing the L's to Q's, Brian says that Mach uses Q not l's

As for the Gcode, just ask me and I will tell you what you want to know, I have been writing Gcode for 2,3,4 and 5 axis for nearly 30 years

Hi Chad,

no problem, I have done a mod to the tapping code based on the user feed back, last time it was used, the person did 570 holes with out a problem.

Hi chad,

 just have a look at this topic, the gcode is for doing just what you want,

you will have to change the feed rates to match your tap and the L words to match your line count and that will work
