Posted · UM2, upgrading stepper driver

Hi!

I have been toying with my UM2 for a good while, ugrading to a "+", installing the awesome Mark2 kit, and so on. I have also been playing with a cheap chinese printer, where I added the great and modern Duet2Wifi card. I love that, and especially I do appreciate the silence offered! I do like the UM2 intuitive scroll-wheel and screen, and my wife knows how to use it. So I would like to try to simply silence it down, to keep it modern and working all night long. 
So, to change the stepper drivers for say, X&Y to begin with, what model could be recommended, genuine Watterot 2208? And how "drop in" would it be? I got a cheap solder iron and an itch! I guess its a question of de-soldering, soldering the new ones, the right way around, and a minor change in the software?

Well If you find replacement stepperdrivers for the A4988 it would be as easy as "desoldering de A4988 and resolderind the XXXX" (and eventualy change some things in the firmware). But as you can see on the picture below the stepper drivers are very small. For me this change would need very good soldering skills and would still be risky... An ultimaker main board is quite expensive. (Unless you buy a cheap chinese clone)

Personnaly I would not try it and rather think to change the whole main board (for a Duet2 Maestro for example) but in this case and do not know how much work it is with the firmware...
