Farmbot length and home calibration

Hi, I’ve been trying to calibrate the range of movement of my farmbot with the “calibrate X/Y/Z” buttons on hardware options which takes a lot of time to do (moves way too slow), is there a way to introduce the length directly?
I am using motors without encoders and just 1 limit switch on each axis.

At this time you cannot manually set the length of the axes, but we will put this feature on our software roadmap. Thanks for the suggestion!
