Einstart-s hardware: How to take apart?


Hey so recently I had an issue with the Einstart-s printer. It seems that the extruder is catching on the filament causing under extrusion on all my prints (has a clicking noise as it prints).

So now I want to take apart the printer to see what might be causing the issue but Shining3D has no information on taking it apart. I think once I can take the plastic cover off the extruder I should be able to see it. I’m scared of taking the filament feeding tubes out though because I don’t know what the release mechanism for it is.

I was wondering if any other Einstart owners took apart their Einstart printer?


@tanya_Wiesner? Not sure if you’ve taken apart the Einstart, but perhaps you may have some ideas on the plastic top on the extruder? Does it seem hard to take apart?


To remove the feeding tube,press down on the blue tab surrounding the feeding tube as you pull it out.


Okay thanks! I’ll try that out.


The “clicking”(or"ticking")noise, is the extruder motor skipping steps(no damage), b/c the temp is too low, and it can’t push the filament into the heat tube(chamber/nozzle)
If you are still getting some extrusion, then there is no problem with the extruder. (but if you ever do get a complete jam, then knowing how to remove the “bowden tube”, and hand forcing the filament into the extruder, while hot, and in the loading cycle, is a skill you’ll need to know)

I’m looking at the default setting in 3dStart, and I see 195C @ 50mm/s. Either raise the temp, or lower the “print speed”. Try 200C. If it is a small print item(>2x2"), then 195*C is ok, just lower the speed to 35or40mm/s. This is the art of 3d printing. You have to learn to balance the energies (temp & speed) that you use, to match the size and detail of a print object.(also to your specific machine, and slicer characteristics)

Protip: Measuring your filament for proper diameter is also important, but I see 3dStart does not have a dialog box to specify that. (So, get out the calculator, we’re going to have to do this the hard way).
Instead, they have the old-fashion “extruder speed”. Meaning: the default is 50mm/min (=0.833mm/s). That is crazy! e.g. 1.75mm / .83mm/s, would = 2.10mm filament ???
Or, (actual condition) 1.75mm x .83mm/s, would = 1.45mm filament. SO, ofcourse it is going to “under extrude”.
When you are ready to experiment a little more, try setting it to 60mm/min, (=1mm/s) (=100% of filament diameter)
Once you have measured the actual diameter, you can use this math to tweak their “extruder speed”, to dial in the filament perfectly.

historical sidenote: RepG and Makerware were infamous for using this antiquated formula. Their default filament size was 1.83mm, and “extrusion rate” was .9, = 1.64mm. That was b/c, back then, filament size did actually vary that much.
Modern slicers allow you set it to 1.7xx (within 1,000th of a mm = very precise)
So, when filament makers claim to be within .05%, that is actually very sloppy(1.75 +/- .05% = 1.64 to 1.83)

Hang in there. It’s easier than sounds. It just takes time to figure-out the different approaches to any given problem. And advice terminology will differ, depending on which machine or slicer that folks are using.



Thanks for all the advice! I took what you said and tried increasing to a higher temperature (205C) and a test print came out fine!

The reason this problem was weird to me was that I have used the default(quality) settings of the 3dStart for many of prints using the same filament with no issues. Just suddenly stopped working.

Anyways thanks again,and yes I have to keep experimenting to see what settings would be best.


Excellent. I like 205, better layer bonding. That is probably as high, and fast, as you want to go for now, until you look into adding an additional cooling fan,w/shroud, that blows directly on the print, to prevent stringing. You’ll actually get better prints then (nice crisp corners). But, no rush, perfect your skills that this level first.



This sounds great, but I cant find the extruder speed setting in 3D Star. Can you show how to access it?
