My computer lost connection with the maslow during a cut. Now it says I need to recalibrate. My question is can I use the number’s on the settings screen to get through calibration faster?

The only part of calibration you need to do is ‘Actions/SetChainLength-Automatic’. The rest will have been presereved in your groundcontrol.ini file.  
The chains need recalibration because loss of USB often causes the Arduino to lose power before it has a chance to save it’s current position.
