Is I had my ABL workig good and printing good. I decided to shorten the plunger for the endstop and make it out of abs. So the problem is after I adjust for the offset like zennmaster does the hot end wants to push into the glass. I have tries recalibrating it many times with the same problem. I have also tried with a fresh firmware with my numbers put in and still wants to push into the glass. I don't know what to do next and need help from this awesome forum.
