      well here another little update , duet 3 6hc has been ordered , only things left is the expansion board and a few minor things to buy to get this baby online for some test .
      hot end assembly minus water cooled loop and a few things. ended up going for a klicky for probe . it is sitting at the front of the air duct close of the nozzle .

          Well my duet 3 6hc 1.02 finally arrived now waiting for the expansion board to show up and i will be able to finalize the wiring and fire this things up soon and do some test , my original plan was to run a single water cooled loop to the extruder and hotend but the tubing couldn't make the bend , so decided to use a Y splitter in the back that come from a bigger tube for the loop and split in 2 . than split back in 1 .

            @Dad003 wow that looks like a lot of water. Is that water cooling form an existing design? I found when messing with watercooled hot ends years ago that very little water was actually needed as its such an efficient conductor of heat.

              @T3P3Tony it a Vzbot extruder and hotend , water cooled version , but the rest is just my own idea , like I said I wanted to do a single loop but couldn't have both cooled , the ultimate Goal is to have this things in a 80-100c heated chamber for Polycarbonate , will it stay like this I don't know , I have lots of testing to do .

              All pass throw a 360mm rads to cool off . Honestly can't wait to have this monster power on lol

                Eventually, a spring over the tube helps against kinking?
                But this works only, when the tube isn't to stiff.

                    swapped my 3d printed bed base for some basic aluminum parts , they are a bit crude lol i have limited tool at my hand for that but they will be good enough .

                      @Dad003 That looks like a piece of cast tooling plate. That means it is flat. 3 points define a plane, not 4, so trying to tram with 4 screws is not a great idea.

                      You might want to look into a kinematic mount for that bed plate. As it heats it will expand. That means something is going to have to flex and that means it will shift out of tram. A kinematic mount has 3 bed support points and just two tramming adjustments. It allows the bed to expand without causing anything to flex so doesn't go out of tram.

                        @mrehorstdmd it a voron 8mm thick plate , and I will use a glass bed on top I don't think it will warp much to make any issue , time will tell anyways

                          z axis belt have been put in , and the pulley ratio are doing their job well , bed is not dropping free working as intended . just waiting for the expansion board showing up in the mail to finish wiring , and organizing the last few wiring . with a bit of luck i might be able to test print this monster next week-end , still need to enclosed this things but it not my priority right now that for a later stage

                                  So got the expansion board up and running ,

                                  Just need to work out a few sensor and the config and then i can put the xy axis belt on and fill up that water loop hopefully this weekend

                                    wiring is all done , basically only things left is to go throw the config and make sure axis and limit switch are good , need to replace some of the 3d printed gantry to aluminum , added an extra thermistor that will monitor temp of the gantry between both watercooled hotend and extruder . tested the cpap fan and it work even at 5% and it feel stronger than most fan ive tried before at that level , cant wait to test that baby at 100% lol were we come with speed run benchy lol

                                    just need to dremel it a bit to get it closer of the 3d printed part and clean it a bit , might be a bit crude but him not worried about that lol

                                      Had to redesign some part , there was a few issue but i might have this thing going today ! Reprinted a few part overnights , and hopefully they fix the problem then I only need to fill up the water loop .

                                          So now I need to calibrate things a bit more but I ended up doing it quick I wanted to test print lol

                                          So far it seem the single 2020 were the z axis rail is, is not stiff enough and make the bed shake a bit , so I will need to had Some reinforcement to stiffen that . Need to work on my klicky dock as well . test printed with some old PLA that i had laying around ,

                                          current setting in config is :

                                          ; Axes
                                          M584 X0.0:0.1:0.2 Y0.4:0.5:0.3 Z1.1:1.2 ; set axis mapping
                                          M350 X16 Y16 Z16 I1 ; configure microstepping with interpolation
                                          M906 X2400 Y2400 Z1200 ; set axis driver currents
                                          M92 X80 Y80 Z2560 ; configure steps per mm
                                          M208 X10:205 Y-40:200 Z0:300 ; set minimum and maximum axis limits
                                          M566 X900 Y900 Z100 ; set maximum instantaneous speed changes (mm/min)
                                          M203 X90000 Y90000 Z500 ; set maximum speeds (mm/min)
                                          M201 X20000 Y20000 Z500 ; set accelerations (mm/s^2)

                                          him curious to see how far i can push this machine once i fix the last few things

                                            so a bit rough looking and lots of stringing from the old pla but not the worst benchy ive ever seen since it on an untuned machine , lots of stringing lol
