We smoothly ramp down to the corner end speed via easy to read E commands

These two lines set the initial feedrate. This feedrate needs to be established before any E command ramping begins.

This line contains an E command and smoothly ramps up the feedrate from the initial 3.62 ipm to the normal cutting speed value (from the quality settings selected in ProNest) of 9.05 ipm across a line segment of 0.075" in length. Note: a space is required between the length value and the E command.

This line smoothly ramps down the feedrate from the previously established 9.05 ipm value to 3.62 ipm across a line segment of 0.04" in length. This is the last line segment before the corner and the 3.62 ipm value represents the Corner End Speed value.

This line smoothly ramps the feedrate back up to the normal cutting speed value of 9.05 ipm from the previously established Corner End Speed value of 3.62 ipm across a line segment of 0.04" in length. This is the first line segment after the corner.

Repeat this technique for each corner.
