Hello All,

The existing BigBox 1.0 and 1.1 uses a Rumba controller.

My Kickstarter BB V1.0 has a 24v power supply and two PT100 thermocouples with adapter boards to interface to the Rumba. (assumed needed as the Rumba is designed for thermistors?)

There are various mods suggested for the BB, fan control circuits, Astrosyn damper for the Y motor, different stepper motor driver boards etc.

My interest in the DuetWiFi is to avoid doing most if not all these mods (most related to noise) , some of which need additional parts printed, with the possible exception of the fans which even if I can get away with not having fan cooling for the Duet I will probably leave and install a fan control circuit so I'm covered regardless, fans only coming on if things get hot.

The other advantage (not the least of which is UK design and support!) is not having to constantly compile and load new firmware, being able to do this on-the-fly is a major advantage.

What I need to know to meet the next order deadline is other than the DuetWiFi board itself and the new screen what if any other hardware do I need to order?

On the order page

There is no technical information on the eight available hardware options (six with photos two without). As I have PT100's already and working e3d V6 extruders then I don't need the last four items. I assume I don't need the IR probe as assuming this is the same/similar as the IR (Z height) sensor on the BB. The panelDue 4.3" screen I do need The type K daughterboard I don't need as I have PT100 thermocouples, so that leaves the PT100 daughterboard?

Any help on this appreciated so I can go ahead and order.
