I have a 7633 loaded with a 7b53a and a 7a26. When the 7b53a is put into XY mode i get a fine horizontal adjustment from it, but my vertical adjustment moves diagonally. When I remove the 7b53a and put in my 7ct1n curve tracer and use it with the 7a26 I get normal vertical adjustment. Anyone experience this before? Thanks for reading!
