My Second build (in progress)
-
i Went with the LDO , super power HT for my build , they have nice spec for a quick machine and 180C temp max and since they will sit outside the heated chamber we should have a good margin. pick up the 55mm shaft version as well so i could add an extra bearing to support the end .
-
slowly been working on it , here a little update , ive been slowly ordering part, thinking and designing more things .
-
well him still slowly building this , still have to buy a duet 3 and an expansion board , but currently in canada there is no duet 3 6hc in stock anywhere , and i have to buy silicon heater for heated bed and heated chamber . anything else is already here , 12v psu for all the fan and water pump , 24volt for the expansion board and hotend , and 48v for the main mobo for xy axis. i need to print myself some riser for the din rail so they sit higher a bit so they are easier to wire .
-
well i think i got my layout all done now , had to go with some smaller cable tray for the top since i was a bit space restricted but it should be enough . fun part to come is to wire everything which is gonna be interesting lol , main duet will be on the right and expansion board on the left . both will have a 120mm fan to cool off the mobo . on top of the 3x120 sucking air for the radiator .
-
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 .
-
started to work on some of my wiring a bit mostly for the hotend so far ,
-
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
-
@Dad003 said in My Second build (in progress):
but the tubing couldn't make the bend
Eventually, a spring over the tube helps against kinking?
But this works only, when the tube isn't to stiff. -
@cosmowave I didn't think of that .
-
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
-
got the lED light and heated bed and heated chamber heater plugged

-
@droftarts danm autocorrect lol
-
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
