We have an old GSM1 (I-block, USOS V1.4.14, two 4-spindle heads, changers between rails). When I configure machine so there are no nozzles on heads and changers are filled with required nozzles, except for one empty hole, machine won't pick up nozzles at the beginning of a program. Boards goes in, gets clamped and machine stops with the head in zero position. Start button goes off, and no messages are shown...This condition stays infinitely. Air is OK, changers can be engaged manually in diagnostic mode. Everything looks fine except it does not work. If I fit nozzles manually on heads (and configure machine), it works fine. I must add, that it worked in the past until once it dropped the nozzle while changing. Machine stopped, I opened it, fitted nozzle manually and re-configured. Program was finished, but after that I can't get it pick up nozzles any more. To me it seems like it saved some information which confuses nozzle changing algorithm. Any ideas?
