It has happened on several different builds this week. It is enough to cause some defects after reflow on small parts (0402) and rnets. </div> <div class="e_p"> I dial it in using double sticky tape and then after 3-5 boards it is off in the x again, usually back to where it was earlier. The Y has also needed adjustment, but not quite as much. </div> <div class="e_p"> The PCB seems clamped securely. Part heights are correct. The machine is older 13714.5 hours on the counter One other symptom this morning is the 8 pin standard soic with 1.27mm pitch parts are way off in the x. .15-.20mm </div> </div>
