Rapid Rate Calibration

Hello, I’m trying to calibrate Carveco Maker to my 30x30 in regards to Rapid Rate. How do I go about finding that number so my toolpath summary predicts a more accurate time?

You can view the rapid rate in the firmware settings 110-112 in gSender. The default rate for the X and Y is 4000mm/min or 66.67mm/sec.
