One of my PCBs and two automatically place Rectifiers
It took me a while to figure out why the rectifiers were misaligned. When new nozzles are installed, the software can measure the nozzle position for various rotations, compensating for a slightly bent nozzle. My "Nozzle Threshold" was set too low (was 45, now 85), and the software would not recognize the nozzle hole. After correcting this, the left nozzle places the parts perfectly. The right nozzle places with a healthy offset - still figuring it out. Also, please see the tvm802a_mods.html Sun Visor Mod on the next page.
