I'm trying to cut half of a circular bore into a block of aluminum with Mach2. After the G2 is executed (see code below), the machine stops for a moment and continues on. It happens whether the feed is fast (150 ipm) or slow (10 ipm). Though, it does become more pronounced as feed is increased (i.e. at 10 ipm, the stop is so brief that you need to keep a finger on the table to feel it). Also, increasing or decreasing motor acceleration seems to have no effect.
Here's the snippet from my code:
G64
G0 X0.8375 Y-0.3750
G1 X0.8375 Y0.0750
G2 X1.2375 Y0.0750 I1.0375 J0.0750 <--pause occurs after this line
G1 X1.2375 Y-0.3750
G0 X0.8375 Y-0.3750
M30
This is the exact code I was using to test the effects at different feeds. Angular CV Limit (on the Corrections screen) is set to 180, Motion Mode (in the State... config window) is set to Constant Velocity, and the pulse rate is set to 25kHz.
Any ideas why this would be happening? BTW: I'm pretty sure that Mach2 is staying in CV mode because the entry into the G2 is smooth and the green light does not flicker.
