[Zo...] Posted October 15, 2020 Share Posted October 15, 2020 After manually aligning my part and run it in CNC mode, all probes are offset by approx. 1/8" or so, but cannot figure out why. The part is set vertically and I am using the #5 left probe to scan. The part has more features, I only show the back face. I realigned it, and the same happened. As shown on the picture, the red circle is the probing path, and is supposed to be concentric to the part. I am not scanning the hex on the picture, the probe "fell off" What can cause this? and how can I fix it, without rewriting the program. I could, but most interested in finding out the cause. Thanks in advanceIMG_5010.JPGprobing path is off centered.JPG Link to comment Share on other sites More sharing options...
[Cl...] Posted October 15, 2020 Share Posted October 15, 2020 You might try re-qualifying those probes to start.. How are you aligning (Base Alignment) the part? Link to comment Share on other sites More sharing options...
[Zo...] Posted October 15, 2020 Author Share Posted October 15, 2020 Please sign in to view this quote. The probes were re-qualified just yesterday. I use the OD of the flange for X and Y, scanning the back face, shown, for spacial and Z, and scanning 1 hole for planar Link to comment Share on other sites More sharing options...

[Zo...] Posted October 15, 2020 Author Share Posted October 15, 2020 Please sign in to view this quote. I was using the OD, changed it to the back bore for XY, but now I get the message either way Link to comment Share on other sites More sharing options...

[Ma...] Posted October 15, 2020 Share Posted October 15, 2020 It seems like your spatial rotation should be to Z+. Link to comment Share on other sites More sharing options...
[Cl...] Posted October 15, 2020 Share Posted October 15, 2020 It looks like the part is in the YZ work plane? That being the case, the flange OD should be Y & Z origin. Back of Part should be X spatial and origin. Link to comment Share on other sites More sharing options...
[Ma...] Posted October 15, 2020 Share Posted October 15, 2020 Check for blocking movement planes ( in CNC menu ) if it didn't swap machine table plane ( those checkboxes with circle around them ). If it's not swaped ( rounded are down as Z- ) then you can correct it by choosing right spatial axis. If it's swaped, then you got to point where i usually create new program from scratch ( i did not found a solution for correcting it ). From screen it says, that spatial plane is X+, so it can not be setted for Z origin. Also alignment can not be calculated because of this. Link to comment Share on other sites More sharing options...
[Zo...] Posted October 15, 2020 Author Share Posted October 15, 2020 Please sign in to view this quote. I changed the origins, and now it works. I cannot believe I missed the X and Y origins, I had them set wrong. Changed the X to the back plane, the Y to the ctr of bore, and the Z offset from the back plane, also the clr plane for the planar rotation is changed to Z+, and now all good.🙂 Link to comment Share on other sites More sharing options...
[Jo...] Posted October 15, 2020 Share Posted October 15, 2020 Please sign in to view this quote. In my experience, when you create the alignment for the first time, Calypso picks the correct axis 99% of the time using the features vector. If you go back and alter it, it doesn't seem to update.

[Cl...] Posted October 15, 2020 Share Posted October 15, 2020 Also, if your working with a CAD model, open up the Base Alignment box and extract from the model the features you want to use. Calypso will populate the Base Alignment with those features in their correct location. Link to comment Share on other sites More sharing options...
