New Duex2,3,4,5?
-
One of our printers is quite large and we decided to use M542 drivers for 3Nm nema24 Z axis motors.
The printer works on RUMBA (Atmega 2560) electronics by RepRapDiscount and we just connected M542 instead of stepsticks.
They work very well.
Another thing is we tried to use servos with DCS 303 drivers from leadshine. It was a great learning opportunity although we dropped it for a while because of some positioning inaccuracies probably due to signal duration differences.So rounding things up…DUEX is a very special thing used to build extraordinary machines and force them to tackle impossible tasks.
It could have some potential for some of us to have the STEP and DIR pins broken out which not neccessary is a hard thing to do depending on development stage. Probably it's late to bring it up or it already had been but I found the forum a few days ago just to be staggered with how dunamic it is and put this idea.External drivers possibility all the way.
