Duplo x45 vs x46 series

[waterfall]

I am trying to figure out the differences between the Duplo 645 vs 646 and 745 vs 746.

It looks like the x46 are slightly faster. But i can’t figure out what else has changed. Any one upgraded that can tell the differences?

also, does Duplo still service your x45 series machines? Not sure if they still make parts for those.

Thanks!

If you get any of them, make sure that the servo motor counters are accurate before signing off on acceptance. A good way to test that is to run a 27up business card job on 13x19 and see if the cards are consistently cut and the same from start to finish of the sheet.
