Trying to get a grasp of g code, I am doing a demo as a learning experience on Mach3 . so I put in the g code as seen in the photo which is attached thinking I was going to see a series of 3 circles along the x axis the
first having a radius of .25" and the 2nd and 3rd having a radius of .5". do I need to get a bottle of Jim Beam or what? It s rather difficult to see result on this photo , but its showing 3 concentric circles ... thanks for the help

Try changing the IJ mode in General Config to Incremental.

Try this

G0 X0.25 Y0.0
G3 X0.25 Y0.0 I-0.25 J0.0
G0 X0.3125
G3 X0.3125 Y0.0 I0.5 J0.0
G0 X1.375
G3 X1.375 Y0.0 I0.5 J0.0

I spaced the circles 0.0625 apart, and removed the z moves for clarity. I generated this in CamBam. CamBam normally breaks circles into 3 or 4 arcs, but I edited the G-code to make it one continuous circle just to make it simple. This has 3 circles along the X axis in Mach3

thanks, that did solve the problem.

thanks a lot, I did what ger21 recommended and that did solve the problem.
