Is JP4 set to RS232 (pins 2-3) or RS485 (pins 1-2), it should be RS232.

Is the selector wheel set to zero ?

CAD systems usually work in units, its the post that sets inches or mm's, if you look in the posts you will be able to set them to inches.

Attach a post for us to look at.

Or if you only want to change 1 variable :

#1=1.5
#2=[#1-[#1*2]]

Hi Paul,

Welcome to the forum.

The G28 command is used to send the machine to zero return :-

G28 Z0
G28 X0 Y0

To set offsets in program you should look at G10 or you can use # commands

#1=100
#2=25.
G00 X[#1+#2]
Y[#2]

G-Code, CAD, and CAM discussions / Re: Current point same as end point alarm

« on: March 26, 2007, 07:13:49 PM »

It looks the same but its not.

G03 with an R calculates an arc from where you are now to the end point

G03 with an I,J is an offset from the current point.

Your first bit of code is already at the end point so can't calculate an end point

Your second bit of code just moves by the I amount.

The R command in a G02/03 can not do more than 180 degrees.

If you are trying to mill a hole you can do :-

G00 X-5.378 Y-3.25 Z.1
G01 Z-.38 F2.
X-5.506 F3.937
G03 I.128
G00 X-5.378
G00 Z.1

This will do a full 360 cut.

I don't use the NFS programs so I can't check it but it looks like a cutter compensation error to me, can you change the lead in/out options.
