Thank you for your reply. An alarm occurs on the device. Of course, if the tool radius compensation is set to COMPUTER, no problem will occur. The problem arises from CONTROL. There is no problem with the view. G03 X-143.542 Y147.077 R2.5 G01 X-143.543 Y147.078 However, there is a problem with the special machine. That's the machine I use. The G01 section is -0.001 difference from the X coordinate. The Y coordinate is 0.001 difference. Because of this difference, the G41 tool radius compensation does not occur and it appears that the alarm occurs.

I use MPMASTER POST and an alarm occurs. T16 M06 (4 FLAT ENDMILL) M01 (MAX - Z100.) (MIN - Z-4.9) G00 G17 G90 G54 X-203.01 Y202.869 S2500 M03 G43 H16 Z100. M08 T17 Z2. G94 G01 Z-.49 F600. G41 D16 X-204.707 Y201.172 F300. X-147.078 Y143.543 G03 X-143.542 Y147.077 R2.5 G01 X-143.543 Y147.078 Use millimeters. I use a 4-pi tool. compensation type is control. G3 followed by "G01 X-143.543 Y147.078" appears to generate an alarm due to the 0.001 difference in the instrument not being able to apply tool radius compensation. Where am I supposed to edit in the post? help me plz. mastercam 2018 used. ㄱ 0512-1.mcam 0512-1.NC
