I am having trouble with my shapeoko pro xxl. I cannot seem to get the depth right. if I set my zero to the top of the board I will get the correct height on the design but it cuts out too deep making tabs completely pointless. but if I set the zero to the bottom then the design depth is almost 3 times deeper than it should be. My suspicion is that I don’t have the bit setting in the correct spot but I am having a difficult time finding info about my bitsetter. any suggestions?
Which Z-axis does your machine have?
Which have you configured for?
If you set the origin at the surface of the stock, then jog up 1" how much does the machine move?
Reconfigure for a Z-Plus?
so you’re saying reconfigure the machine from the beginning? I am not sure what kind of z axis I have. when i plunge to 1" above zero it is exactly 1 in above zero.
If you have configured the machine correctly, and if you are setting the origin at the surface, jogging up 1" and getting 1" when measuring, then the problem is with the setup or .c2d file.
Post your .c2d file and let us know step-by-step how you are securing your stock and setting zero relative to it and managing all tool changes and post a photo showing the machine at the zero or a specified offset from that position.
The HDZ has more steps per MM than a Z-Plus. So if you have a Z-Plus but configured as an HDZ then you will cut deeper than expected.
Another thing that can happen is when using the BitZero. The BitZero has two sides on the bottom that are longer than the other two sides. So when you use the BitZero on the corner you hang those longer sides over the edge. If you put the longer sides on top of the material you will not be zeroing correctly. If you are only setting Z zero then it is normal to put the longer legs on top but if doing an X Y and Z zero on the corner the longer sides must be placed over the edge. That is true for the V1 or the V2 BitZero.
When starting a probe you are asked the type of zero you are doing. So for an X Y and Z a macro is run internally to compensate for the height difference between the long sides over the edge and the long sides on top of the material. When only doing a Z zero a macro adjusts for the height of the two longer sides and so the height is compensated for inside CM.
Ok so I gave that shot. However, I had realized i was already configured to the HDZ. So i set it back to z plus and that seemed to solve it.
