I like Uwe's chamfer method:

;------------------------------------------------------------------------------
; Filename: MPGmacro1.mac
; Description: Turn a 45° chamfer
; Notes:
; Requires: Machine home must be set prior to use.
; Please see TB300 for tips on writing custom macros.
;------------------------------------------------------------------------------

IF #50010 ;Prevent lookahead from parsing past here
IF #4201 || #4202 THEN GOTO 1000 ;Skip macro if graphing or searching



N100 ;Insert your code between N100 and N1000
G97
S1000 M3
G4 P0.5
G99
G1 U4 W-2 F0.1 ; incremental in +X
W-0.05 ; finish amount
U-4 W2 F0.5 ; incremental back to start
M5
N1000 ; end

Thanks for the tip on where to position the tool before programming a chamfer. "all the manual has to say is position the tool tip where you want to start the chamfer before programming a chamfer"
Wouldn't it be easier to have a centre point for the middle of the chamfer and how long you want the chamfer length.
It is so frustrating the way intercon works, not exactly user friendly which is how it is supposed to be.

This is the way all Intercon and G-code moves work. They all expect the current move to begin where the last move ended. This gives YOU the flexibility to program any moves you need to clear the work or any fixturing components like tailstocks, driver dogs, faceplate clamps, etc.

This flexibility allows the routine to work with IDs, ODs, left-to-right, and right-to-left cuts. Admittedly, this complexity makes it tough starting out, but makes Intercon an extremely capable conversational programming method once you master it.

I’ve read the manual. It doesn’t have much to say, nor does the help screen. I was told it’s not really a conversational screen which confuses me more. My hope is to not have to use CAD/CAM. I’m currently using a file after the cycle is complete.

I have just made a chamfer on a part at 45 deg but can be any angle. If you just use intercon "turning OD" you can tell the lathe to turn a TAPER on the outside or the inside of the part. It asks for the starting position and the start and ending diameter and gives you the length of the tapered portion.
It worked for me, and you can specify the depth of cut for roughing and finish pass.
