Hello
After 3 printers that worked poorly I decided to build my own Im copying a really good design but all the connections are 3d printed so I’m making it up as I go along
Not sure what to do about the hot end how to attach it to belt on x axis and cool it any ideas? also what length screws are best I’m building it with 2040 extrusions I have m5 nuts
Thank you
which one are you building
Was the best one I could find unless there is a better one out there?
Pretty much ordered all parts but there are a few printed parts for it, but don’t have a printer 
Only think I’m stuck on is hot end and a few of the printed parts that connect everything up.
lots of people cna print a few parts for you
maybe talk to @Lee_Wright as he has access to get good stuff
Hay thanks will give him a shout
Hello
Wonder if someone in the uk could help me out with a few prints please building a printer which I’m struggling to copy need these special brackets to finish it would sure appreciate it will obviously pay of course.
Thank you
Thanks
Wonder if anybody who has built their own printer why length bolts to use?
I’m using 2020 and 2040 extrusions
Thank you
Where ever you bought the extrusion from should also sell the appropriate fastenings.
I have tried that
Can anyone explain what’s going on here? Just installed Microswiss hotend and direct drive on the Ender 3.
Aside from retraction settings (1.5mm distance, 35mm/s speed)
What’s your print speed/acceleration? It kinda looks like ringing, where there’s excess inertia from the print head moving around. Direct drive adds quite a bit of weight to the moving head, so my guess is that extra inertia’s causing a bit of overtravel.
I think it is overextruding. Reduce all the flow to 90% and give it a go. You can later calibrate properly.
I was narrowing it down to 2 possibilities. Print speed and underextrusion.
It was printed at 60mm/s so I lowered it and it’s still seeing the issue so now I’m moving onto underextrusion.
I was pretty certain I set the esteps properly. I measured out 10mm of filament, told it to extrude 10mm but I ultimately had to set esteps to 135steps/mm
Maybe clogged nozzle…?
Oh damn @mishrasubhransu overextruding? Okay, I’ll try that after this next test print.
Thanks guys!
Do your e-step calibration again. Thank me later. 
One more for over extrusion
10mm is way too short to give you the accuracy you need, IMO.
I’d suggest trying that again, but with 100-200mm of filament, to give you more accurate measurements.
(A 1mm measurement error on 10mm is 10%, whereas the same 1mm error in 100mm is only 1% - ten times more accurate.)
The length of the filament extruded out is only an intermediate metric. Print quality/strength is the final metric which we should be focusing on.
