I noticed the last couple of days that when I attempt to manually override some of the values in the iOS feed/speed pro calculator that they don't lock and keep reverting back to default values. I've only gotten it to work once then haven't been able to get the same result again after changing some values then attempting to come back around. Using solid end mill, carbide with TiCN coating on hardwood. Trying to set rpm, depth of cut, width of cut, and chip load to find the feedrate required. When I try that it keeps jumping around. When I override those values (in the order I listed), it reverts back to default for the width of cut. Not sure what else would revert back to default if entered in a different order. Please fix, as this is holding up my production :)
