i am making these to sell on ebay if you want one and do not have the tools or patiance of making these they are a lot of milling so far i have 3 single cooling blocks about 8 heat blocks and 1 or 2 duo blocks also there are 2 differant duo blocks the old style has 2 screws to hold to the box and the new style has 1 screw and a square block i have made templets for both but have not uploaded them yet not till i get all the bugs out of these templets the duo templet that is here is the new style i do not have the tubes or temp sensors the tubes also have to be milled they have to be cut to 34mm and the end to the inlet side threads has to be miled down to clear the guide wheels and end to be cut with a dremmal to keep them from shreading filament as it goes in i have not found any that do not have a sharp end going in and i have orderd quite a few and i also have to find tubes that do not break when you tighten the nut on the cooling block i think i have found some with the last ones i purchased seem to be pretty strong so waiting on new month to order these parts i am still working on templets to get idot proof blocks and i am the idot to proove that it works so there are more templets that i have not uploaded still working on them if you have a PRO modle you can print and use the E3D drop in some pepole have had good luck with this drop in and i have noticed that E3D has droped thier nozzles to a more reasonable price others not so much that drop in only works for the PRO moddle and can not be used on other xyz non bowden printers this mod should work on all xyz printers you can use any standard heat block except E3D with this mod i have tried these blocks and had nothing but problems and calibrate by hand i have ben calibrating xyz nozzles by hand for quite some time because xyz calibration always sets the higth way to high and is just a pain in the butt now you have the option of setting the calibration higth for your own preferance and i am finding that using xyz calibration is better than manual esp for the DUO and ++++ now you do not have to tear the whole dam thing apart to fix a pluged nozzle just using a wire to clean the nozzle only works for a while because all you are doing is pushing what ever blocked the nozzle up and eventualy it will move back down and block again when you least expect it like a 5 hour print at the last 5 layers to set the calibration screw set the nozzle down on the bed by using the home function then hand crank the y screw till the nozzle is down on the bed does not matter how hard it is on the bed then using thickness guides set the DUO to .50mm and on the AIO set to .25mm i am now noticing that i am able to use the normal setting in xyzware for printing with good quality prints i have never ben able to use this setting with out pretty bad print quality you will see by the print pictures how much of a improvment this upgrade is to the standard xyz nozzle and it is worth the time to mill the parts i have made pictures of recyled filament sure any nozzle can print good prints with good filament but the trick is can it print good quality prints with crapy filament all these prints was done using a brand new xyz stock nozzles with out my fan upgrade my aio and DUo used to print perfect prints for the first year then they both started printing pretty poorly so i bought a new nozzle ,print bed,ect ect and nothing i did solved this problem the black xyz single carrage was printed on my aio with good filament you can see the horable print job that xyz did and the perfect print of this mod the green parts are using crapy recycled filament you can see that the xyz nozzle has holes and realy bad layering while this mod has perfect layerss a while back some body told me if i could make a better nozzle than E3D that i should do it because they swear by E3D and say that nothing can be made better so here it is i am also looking into using PTFE coated tube these would have on the outside of the tube will be coated with the PTFE so that there is 0 heat transfer to the inside with PTFE tube and outside directing all the heat to the nozzle and then you can use the higher heat block like the E3D and making my heat block with screw Higher the Higher block is better because more threads on the tube can be used inside the heat block for a straighter assembly but right now it is bad news to much heat going up the outside of the tube these would increse the price a lot they are realy expensive also looking at mixing carbon grafite with paint to insulate the tube from the heat block only on the heat block not on the heat sink that has to have the max heat transfer to the cooling block i was arguing about E3D nozzles that i think that they are not worth the money as they realy have not done anything other than put available parts and put thier name on it and charge a exorbiant price do not get me wrong E3D nozles are good in open style printers with lots of air flow to cool them but they realy strugle to keep cool in a enclosed box and XYZ nozles are much superior nozles xyz has eleminated all the problems of a seperate block and nozle like ooz from around the nozzle of corse if you put a E3D nozle together properly you can avoid this problem but xyz has sloved all these problems of alighnment cooling oozing they are in my opinion the leading edge tecnolagy in nozzles and while E3D nozzles was the best in my opinion E3D nozles are now jersacik old tecnolagy but xyz nozzles also create a few other problems that are not apparent untill you try to put the math on it the first problem is the heat block only makes contacact with about 30% of the heat element making the heat elament work harder to heat the block second is the heat chamber of the xyz nozzle is not large enough to push melted filament smoth at a high rate third is the heat block is realy small making the heat elament work realy hard to keep up with the flow this is where E3D and standard nozzles are much better in these departments however E3D heat blocks are to high heating the tube more than the nozzle they have tried to elieveat this problem by moving the heat elament down level with the nozzle but this still does not solve the tube from heating and causing a lot of jams so they then added a lot of fins to slove this problem but the fins and fan are to high up the tube it has to be cooled as close to the heat block as possable this is where xyz nozzle are superior xyz has made a huage heat exchange close to the heat block as you can see niether xyz or E3D nozzles have the perfect solution and one other thing that realy makes me made about E3D is no where can you find print tests to compare do other nozzles because i believe there is no differance in print quality to other nozzles the basic process is the same to melt filament and push it through a small hole putting E3D on the out side does not make these simple process work any better so i wanted to keep the best of XYZ and the best of standard print nozzles i wanted to keep the tube but the nozzle thread dia and the xyz tube end are 2 compleatly differant animals while i think it is possable and i think i have found what i believe is the right thread so i am still working on keeping this just waiting on delievery from china i have ben real heasadent on posting this as it is a complicated procedure to make these parts i was wanting to start to sell these on Ebay but find that this is just more than i can phisacly do i would only be able to make maby 5 a week and because of the complication of making these i just can not describe how exactly to make them if you have worked in a machine shop these are pretty easy but to discribe to somebody else who has no shop experiance with simple tools i am strugeling to do neaded drill press cut off tool or hack saw 2.5mm drill bit 5.5mm drill bit 6mm drill bit 3x10mm screw and bolt 3x.5mm tap 6x1mm tap the idea is to replace the heat exchange block and heat block with m6 threads for standard 3d printing parts also print the hacksaw start guide if you do not have a cut off tool to help to keep the cut on the pieces straight print the guides
