Hi, I am new to grbl CNC. I have a problem using the fixed probe/ bit setter for probing different tool lengths.

I am using the 3D probe to make a corner probe for my workpiece and reset all axis into zero values. Then, I set the current position with G28.1 and key-in G30 in the MDI to move the current position to the fixed probe position that had been set. Now, using carry out the z probe operation and get the z value is -44.795 Change the 3D probe into endmill, make the z-probe again, and get the z value of -56.240. Now I am typing in g28 in MDI and the spindle will move back to x0 y0 z0 (but the endmill not touching the surface workpiece) how can I make it?

below is the attachment video that I have recorded, hope somebody can help me, thx u
