i also want the whole printhead as light as possible and firm. You can faster print then, less shaking.
At the moment i use a dummy of PLA on one side to print my small series of 180 ABS technical parts.
In conjunction with the 0.5 nozzle i could reduce the printing time from 2h16min to 43 minutes.
i print that with closed door, hood on top (a simple household box), 95°C heatbed, 152°C head, so getting aprox. 40°C in cabin, on my sanded glasplate without brim !
We make us the best printers, money can’t buy !
no problem, but please consider: this is my first draft of the headmount. i wanted start printing with bigger nozzles as soon as possible (to get my 180 ABS parts.
i will add more functions, e.g. mount of female connectors left and right. Then elimination of the PCB (wich makes a gap you have to seal at the moment) Perhaps i turn the fan and there is also need to design a new coupler between fan and headmount. i have done a plastic deformation of the original one with my SMD-rework-soldering-fan (no work for everybody, you can easy damage all ;-))
Another question is additional cooling for e.g. PLA parts. At the moment i do it povisional with stationary fan clamped where i need it. Cause i want the printhead light, i will test a row of smal, controlled fans, mounted on the right wall, blowing across the heatbed (like some new 3Dprinter designs i have seen, doing this with a big aligned fan) i have a lot of small fans remaining now from my seven E3D’s :-))
If this don’t work, there is the possibility to bypass some air through the xy-block down with an outlet near the nozzles. This controlled by an rotary slide valve …
Also i made the experience: STL-files are not good for technical parts, the dimensions are depending on your set (printer, material, nozzle, temperatures and 100 other values …), you can’t handle this with variation of x,y and z proportion. Especialy the round hanger in this case need exact size. You can get my “123D-Design” files if you want ? (i design the most with 123-D and Meshmixer, all free software from Autodesk)
