We often get asked questions regarding the PH20, like what probe modules are supported, how long of a stylus can be used, and is a star or knuckle probe supported. Well, linked below is a guide you can reference to answer all of those questions and more.

The guide also covers application issues such as the “critical angle” on slide 17, where the PH20 doesn’t like to trigger 5-axis on holes that are, say, between 0 and 10 degrees of being parallel with the quill.

 This guide also provides the angle of guidelines for 5-axis triggers and some excellent graphs comparing the accuracy between the PH10 and PH20.

 Last but not least, there are some great building blocks to help us all better understand the ins and outs of the PH20 from the inferred calibration, using the tip correct on the rack and using star, disc, and knuckle styli.
