thanks for getting back to me, there's my problem, on the schematics for the Duet2 wifi it says the external PSU is optional, i knew the heat bed and hot end needed external power, i though the usb would power the steppers as it said optional. if i use the PSU that came with the cr-10s, would i need to connect the mosfet(i think its called in the cr-10 box) that goes to input voltage(green connectors) and to mobo(green connector), or can i connect the heat bed directly to the mobo?

The PSU that comes with the CR10S is a 12V PSU, which is compatible with the Duet2Wifi board. Also, the Duet2Wifi board already has a built-in MOSFET on the board used to switch the heater bed on and off. All you need to do is connect the PSU to the Duet2Wifi (make sure the polarity is right! also, confirm voltage with volt meter before connecting... just in case). Then you can connect the heat bed to the Duet2Wifi (also keeping polarity correct!). The CR10S heat bed (300, 400, or 500) is compatible with the power that the Duet2Wifi MOSFET can handle. Make sure you are careful when working with electronics btw! The PSU needs 110/220V AC main power (which is very dangerous if you don't take proper precautions).

A few updates since this all started :)

• Changed my extruder to a Bondtech BMG (Bowden configuration)
• Configured retractions with firmware (using PrusaSlicer mostly with firmware retractions enabled)
• Updated for latest v2 Duet2 firmware (will upgrade to v3 soon -- lots of config changes with this one!)

This is great. I'm considering the Duet 2 WiFi for my S5 with a Bondtech DDS and BLTouch. Did you have to use the adapter board for your hot end temp sensor?
