You could just do a G92 A0

Chances are that the Fanuc 0M will work unmodified.

Please post the Alphacam file you used to produce the code

Hi Henry,

post the code you are trying to run and attach the AlphaCAM file so I can see where your problem originates.

I want to know what the noise is.

If its a loose ball nut or bearing/housing or motor mount then that can cause problems with position.  I would check all the clamps, nuts and bolts first and make sure every thing is solid.  It has been known for ball nuts to be loose in the housing and sliding about.

Its hard to tell, but is that an arc in the ZX plane, if so then you need to use a G18 and then use I & K in the G03 line.

looking at the code you have no G02 or G03 commands so the issue has to be related to the CV settings you have set, increase the look ahead and reduce the feed by half for a start and then see what the difference is.

Do you have I&J set to Inc or Abs in config window?

The highlighted red code should be inside the sub.  its in no mans land there.  Also make sure you have an end of line on the last line of the code.

Graham

O2         (moves axis to different part of sheet to carve heart)
M98 P1 L32        (Calls O1 to cut heart in 0.1mm increments through ¼”metal)
#2=[#2-38]      (advances axis counter)
G52  Y#2      (moves axis to next heart in line)
M99

#1= -0.1
O1         (sub for carving hearts)
Bunch of lines of gcode that inscribe heart
#1=[#1-.01]      (advances depth by 0.1mm increments)
M99

Hi Guys,

sorry for the delay, its been a very busy week so far.

I can see no obvious problems with the g-code, the only thing that can be off putting is Mach3 and a combination of subs and G91 code can cause the tool path to be drawn wrong.  If you are not using tool compensation then the G40's can be removed as Mach3 is not over keen on tool comp codes in subs ether. Blank(s) or comment(s) as the first line(s) of the sub can cause problems too in some circumstances.  Lastly it is a good idea to have a % only as the first and last line of the code, none in the middle.

You will all be pleased to know that Mach4 has none of these problems  

Regards
Graham
