Hello everyone . I received lot of help from people of this forum for which I want to say "thank you" guys. I had problem whit initialization of my Quad 4C which just sits for 2 years after purchase. I manage to locate problem with laser diode on placing head (which is part of quadalign)after sending it to service in Mainland China they fix it and recalibrate it and now is working like new. I wish to ask is there way to continue with placement program after alarm (machine try to pickup component . there was no vacuum) so machine halted , can I continue placement from that point and how to do it? Thank you once again Miro PS. fixing price was cheap compare to what price others ask for.
