I assumed a conservative 25,000 cph for each of the chipshooters...whether it's an MV2F, CP-6, CP-642 etc. You're not going to get 50,000 cph out of (1) CP-643. You might for short periods but not in the long run. It would be suicide to rely on one

My suggestion DEK printers are good, however, we have an EKRA, I'm really amazed, about $4 KUSD in spares and service in 5 years (approx $160 K for a printer) NXT is good, nice high volume, ease of use , quick changeovers, and we just ran them for 10
