Thank you very much for your help. The SOT23 was only a test, which I hope to solve soon.
But now I try to explain my way with new project to understand, how the SMT-880 works.
1. I have installed necessary feeder in the machine and adjusted the height, tested the vision etc.
2. Than I have made a new project and imported a TXT/CSV file with fudicals, the feeder numbers I have intalled before, and nozzle type (1...7 = 504 and 8 = 505)
3. I have generated PCB array and the marks.
4. But when I start "Optimize order" then I have 2x problems :
a.) the feeder numbers will be changed (mixed up), and the adjusted settings under FEEDER before are lost (for example OFFSET)
b.) the nozzle types I set will not be accepted (after optimalization I have suddenly 1...4 heads with 504 nozzle and 5...8 = 505), AND I cant change it under "FEEDER/NOZ. PLUG IN"
I would be grateful for any help, thanks
