Are you using any size modifiers in Windows? If so, that can mess up the sizing. A low resolution screen could too I suppose. But, the size is set to 900 X 530 on lines 555 and 556 in the module itself. Feel free to modify the size to suite your setup. Just save a copy somewhere if you do because if you update it will get overwritten.
There is no fast find or tip travel compensation. When using an actual tool as the probe neither of these are a good idea for obvious reasons. But if you do tune the settings fast find really isn't needed. It's not like it will do 3D probing for hours making thousand of touches nor is it meant to.
It gets the probe position at the time the state of the input changes, not when motion stops so decent probes should give very good results. However,if your using a probe it really doesn't matter if it travels a 1/2 inch after contact before the switch changes state, you could compensate for this by adding the overrun distance x 2 to the tool/probe diameter. As long as the probe works consistently and you do your touches at the same rate you can dial it right in. If the overrun distance of the probe is not the same and consistent in all directions this does not hold up............ but neither does tip travel comp. or calibration.
