I have always thought it would be better if you could see the electric in the wires, like bubbles in water.  It has usually turned to smoke when I get to see it.  :D :D :D

General Mach Discussion / Re: ? Cutter Wear or Comp.?

Basic circle code is this :-

G00 X0 Y0 Z1.       (move to centre of circle)
Z.05               
G01 Z-.5 F2.          (feed into job)
G41 P.375 X1. F4.  (comp on P=cutter dia X= radius of hole)
G03 I-1.                (cut full circle)
G00 G40 X0           (take comp off)
Z1.                       (rapid clear)
M30

Ok, are you using a licensed version of Mach3? , Demo version may not have this function.

What version are you using? I am using V3.037

Have you tried a re-install of Mach?

Other than this I have no idea why mine works and yours will not. Sorry you have beaten me on this one.

Graham.

Here is a screen shot of what my set up is showing.

If you change the display view to table mode you will see the tool path is half size, if you have your soft limits set up then the tool path will show it scaled to the size of your table.

OK,  so why not lay the indexer on its back and work in X&Y ?

The formula functions can be as simple as x*2 so then if you go to MDI and type G00 G91 X1. the DRO will move 2.

The formula would double all X moves in a program.

If you press regen screen the path is scaled not the code, when you cut the path it will be scaled then.

Sorry, no idea, have you tried it on another computer, it seems to work for most people.

Yes it could be done, but for what reason, you would just be making the job harder than it needs to be, or are you trying to do something else?  :)

If you want to mill a circle in the end face you need to tell mach that arcs are on the YZ plane, this is done by G19.

You can then mill a circle with G02/03 commands just like you would in XY plane.

(Mill a 20mm dia circle on YZ plane)

G21 G40 G00 G90 (standard start up lines)
G19                     (set to YZ plane)
G00 X-1. Y0 Z0     (rapid to start point)
G01 X.25 F100.     (feed into job)
G03 K-10.             (do a full 20mm dia circle)
G00 X0                (rapid clear)
G17                     (back to XY plane)
M30                     (end program)
