Have I been standing on my head? For the last three months I’ve been probing Z on the face side of the Touch Probe. I just watched the OneFinity Maintenance video, did my 3 in 1 Oil jammy, and my machine is ready to rock. I bumped into the Touch Probe Youtube video and saw it, figured I would entertain myself. It shows that when probing after homing the machine and readying material for the first time, you should X,Y,Z on the face side of the probe…. And when just probing Z, you should touch on the back side of the probe. Well I’ve been u’zin the face for both! Hahaha!
It seem to be working okay all this time. Just wandering if I’m missing something here!
If you’ve been probing for just z while the raised L sits outside the corner of your workpiece, the height is the same… it’s when you put the raised L shape on the workpiece that it would be off. So far, you’ve got lucky!
Just proof you are capable of working harder than the rest of us but honestly these self revelations are what we all can learn from. I have always been one to post my teachable mishaps to benefit others. Thanks @4KENTT
The main (only?) benefit I see to probing on the back side is that the larger surface makes it easier to sit the probe straight when you have cut corner material.
My 2 cents. Though I acknowledge Z probe can often be used with the locator relief down, I’ve made it a habit to probe Z alone with the puck bottom side up as it allows probing anywhere on the work piece without having to locate to the lower left corner.
All though thinking about it, that is probably the only more efficient part of my work process.
That’s right Phil, it appears that that is the main practicality of it. Being able to Z right where the bit is at over the material, (with the probe face down) no need to go over to the left most corner.
With one caveat, Jenn: you need to make sure that you the probe sits at the same height as the original stock. Don’t place the probe in a pocket just because that’s where you bit is.
Another practical use for doing the flip is when probing z in the middle of the work piece, as many folks want to XY from the center of the work piece, as you may be using stock that is not necessarily square, or your design is based off the center point.
