The only changes I made were to add G21 and G0 to the beginning, and M2 to the end. http://timeguy.com/cradek-files/emc/andy-success.png The preview and machine motion matched. If you are getting a different result, we need more information to reproduce it. Some things that I wonder are: Does the preview look wrong? Does the machine motion match the preview? What exactly do you mean that the arcs are skipped? What else is above in the program that might influence the path? Maybe tool radius or length compensation? G64 setting? If tool radius or length comp, what is in the tool table? Can you narrow down the problem to a very short program that reproduces it, so you can post the entire program here? ChrisThanks for the quick response Chris. I've tried paring back the code to just after the point at which things went wrong and the issue disappeared. It was near the start of the program so I left everything before unaltered. I then added back in the deleted code in chunks, running the code at an elevated z level above the work. With approx 2000 lines it worked fine. Then with the full original code for this tool it ran ok beyond the forth profile level where the problems started. I then reset it back to the original z-level without the tool and the fault reappeared. However all operations are well within the physical boundaries and the red box. I then pared the code right back again to the attached and the fault again arose on the fourth level (N224). The short code and a screenshot is attached. I've also posted the code at the end in case attachments are lost. This apparent Z level sensitivity is interesting. The machine boundaries are set at (X -0.01, 6.67), (Y -2.73, 0.01), (Z -6.78, 0.01) putting the home origin in the top left upper corner. The part (G54) is then zeroed in absolute coord (X2.9361, Y-1.5052, Z-2.1691). All the tool paths appear well within the boundaries and I can see no logical reason for this dependency. I've restarted the program a number of times during these investigations and with the same z zero the errant behaviour is repeatable. <<Does the preview look wrong?>> The preview is correct to the code, but the tool path display matches what the tool did. i.e. a red plot line was drawn where no white line exists. (See attached) <<What exactly do you mean that the arcs are skipped?>> The lines containing the G2 code after that point (I ran it for approx 10 more lines) were ignored by the controller. The debug output in the terminal made no mention of them. The tool motion was consistent with the machine ignoring the G2 code line and enacting the subsequent G1 line immediately, ploughing straight across the part. A sample of the debug output is given below: << Issuing EMC_TRAJ_LINEAR_MOVE -- (+220,+116,+0,1.936829,-2.147814,-5.105566,-0.004303,0.000000,0.000000,0.000000,0.000000,0.000000, +1,0.300000,0.300000,5.000000, +0,)Motion id 107 took 7.317767 seconds.

The tool table line is: <<1 1 5.24 0.24 Touch off probe 2 2 -3.2415 0.250 1/4” endmill in 1/4” endmill holder>> G40 is active, so no radius compensation should be present. The machine is set and remains on G64 throughout. One observation is the active G code display looks wacky. The code displayed does not match that active. This seems to happen fairly randomly. When stopped, both G1 and G0 are displayed (see screenshot). This seems indicative of some sort of bug. Bit of a tricky one, hey? Any insight warmly received.
