I bought the Haydn Huntley delrin and magnets...and I made my own lenght arms...I buy 6mm carbon fiber tube...I made my own caps for the carbon fiber tubes...i print them on petg and then machined on lathe to final shape and dimensions.. using this on my 2 anycubic kossel linear plus...I spent 78$ for parts from Haydn + 24$ shipping fee and another 40$ on customs import fees, and 20$ on carbon fiber rods.. total 162$ ...custom lenght is 115$ each kit + 24$ shipping + custom taxes!. .for having all the rods same lenght I made a jig from a solid piece of aluminium machined on a mill with a shape of a big U where on each side I cut slots for m3 screws and I fix in place 10mm diameter steel balls with m4 holes in that I buy from aliexpress for this purpose...then the rods are glued on one side with epoxy glue and let them set for 48h...then I put them into the jig and glue the other side of the arm,this way I achieved the same size of all 6 arms.. I made 2 sets of these arms...in total 12arms to install on my anycubic kossel linear plus!some photos of the caps and the arms

Assuming you are using 1 extruder, you will need 7 drivers to drive x, y, 4×z and e motors...even if you buy duet 3 you only have 6 drivers onboard...in case you buy duet2 and duetx expansion choose the x5.. the price difference is so low...and maybe in future you want more extruders and you are set with duetx5 instead duetx2

Maybe this can help you out:all my printers are with duet2 wifi, and upon building a printer for a friend with the hardware that he already had included a skr 1.3 and tmc2208 deivers, i came across reprap firmware for lpc boards and so i installed that port of reprap firmware to skr 1.3, and all and all was perfect.. my friend also has a btt tft32 that wanted to have it instaled(after i told him that with reprap firmware you dont need an lcd he still decided to have lcd)
So i installed the lcd to the skr1.3 board and in the config.g file i specified raw mode and i was suprise to see it working...i can do all things from lcd as it was under marlin firmware...nevertheless i have as well an mks 32tft lcd and tryed that lcd and again all working just fine...

@DoxfordC nozzle need to have a certain temperature for the extruder motor start moving...does you preheat your nozzle when you try to move the extruder?

@GeorgeM on the btt tft you need to match the 57600 baud rate as well...if not wont work!

Why not use an external mosfet to power the 24v heatbed? I have the setup above but im using a 30amp external mosfet to power the bed using 2 psu 24v each...one is 250w for duet and motors and hotend, and the other is 350w only for heated bed!the wiring is very simple...

Just open your config.g file and add T0 at the bottom of your config.g

No its not supposed to be missing!where did you buy your board?

@FelixH there is precision piezo orion that do the same thing as smart effector...i use it on my hypercube printer...and i also have 3 kossels with smart effectors on it...and the result is the same...very good stuff...(for my delta printers the smart effector along with magnetic arms and duet2 wifi was the best decision i made, on my hypercube the duet2 wifi and precision piezo orion v2 was the best decision i made)on my cartesian printer(prusa clone) i use bltouch...because is what was the best at that time, though if i had to make it again i 100% go with precision piezo...

What are the drivers on this new duet 3 mini? Subscribe me for the testing when the board came out!

Condolences to the his family and to the Duet3d family...very sad news!😪😪😪
