Hello, mcdvoice It seems like your Juki RS-1R machine's laser height calibration may be off. When measuring a 0402 resistor, it consistently reports heights around -0.60 to -0.70, causing pickup issues during production. Manually adjusting it to -

Greetings, I would like to do a height calibration, because the laser of the machine seems to be out of control, I'll explain why: When I measure the height of a 0402 resistor, I get around -0.60 to -0.70, when I fix it on what the machines has measu

there is an IPC standard for machine accuracy and repeatability. Here it is how it works. You have to place certain number of parts on a specially designed PCB(that allows placing variety of parts on big part of the machine work area). After that you
