Creality Ender 2 ReBoot - a slight overhaul with 161% more buildvolume!

TL;DR first:

Welcome to my Overhaul of the Creality Ender 2!

Im starting here with version V2 (V1 is only in one picture; there was too much wrong with that), which comes in 2 iterations/stages:

++++++++ Stage 1: ++++++++

• changing out the Heatbed to a 150x230mm 12V PCB Heatbed
• changing out the Y-Extrusion
• making a new Y-carriage with 3-point-leveling
• adding a glasbed with holders.

That is the budget-orientated version.

++++++++ Stage 2:++++++++

everything of the above, plus

• bringing everything on the Ender 2 up to 24V
• 150x230mm Heatbed in 24V
• Duet Maestro as the control board
• Mobius 3 Extruder
• E3D V6 Hotend
• 5015 Partcoolingfan
• Duet Maestro Mount for the rear of the Ender 2
• Spoolholder in front

That is a tad more expensive...

++++++++ ++++++++ ++++++++ ++++++++ ++++++++ ++++++++ ++++++++
I leave the printbed-solution to each on their own. You cant print directly on the PCB-Heatbed!
So, you could either take the classic approach, and take a 3mm thick aluminium buildplate,
or go fancy, and put a glassbed on top.
I went extra fancy, and went with glass and a magnetic buildplate. ;-)
++++++++ ++++++++ ++++++++ ++++++++ ++++++++ ++++++++ ++++++++

With both updates, youll get the 161% increase in buildvolume.
The original buildvolume of the Creality Ender 2 is 150x150x200, which is 4.5l.
The new buildvolume is 150x230x210, which is 7.245l, so 160,9% more
buildvolume!

And technically i already lied to you in the title. If that isnt a good start, i dont know any more! \o/

The longer version:

++++++++ Why? ++++++++
I wanted two printers which will fit into the space i still had, and one candidate was the
Creality Ender 2. I looked at everything i printed so far, and came to the conclusion that a buildplate of 150 by 150 would be ok for roughly 50% of my workload.
But while i waited on them to arrive, i found an aliexpress offer, showing 150x230mm heatbeds, in 12V and 24V!
So, i dont have the space for wider printers, but deeper? Thats no problem!
The idea was born.

++++++++ a Mobius 3? ++++++++
I have a Mobius 2 on my two first printers, and i printed close to 2500h on each of the two. They both never let me down, and i like the concept.
The Mobius 3 is easier to print, but slightly worse to maintenance.
I would probably say go with a Mobius 2 when you can.
I will upload a slightly modified case for the Mobius 3 and 2 in the near future.

++++++++ Why a piece of ptfe-tube on the "intake" of the Mobius 3? ++++++++
Thats because im using Capricornus tubing. Thats a ptfe-tube that has an inner diameter of 1.9mm, making your extrusion more consistent.
But if you dont use also a piece of capricornus on the intake of the Mobius 3, and your filament is bad in diameter, and your filament gets stuck on the way to the hotend, your Mobius 3 will push the filament into the small cavity before the push fitting, and maybe push the push fitting out of the Mobius 3 case, damaging the thread.
So you have to reprint the Mobius 3 part with the push fitting to get printing again.

If you have the capricornus tubing on the intake, and your filament gets stuck there, your Mobius 3 will simply rip apart your filament while trying to pull it in, and nothing else will happen. Simple as that.

++++++++ Why an E3D V6? ++++++++
The hotend of the Ender 2 is good enough for the job. There is not much of a reason to switch that out, but i like the E3D V6 more, also its a thing of ease of maintenance over my 5 different printers if all have the same hotend.
You wont push insane printing speeds with an Ender 2 anyway, and probably wont never exceed the capabilitys of either original MK10 (?) or E3D V6 hotends.

++++++++ Why a 5015 for part cooling? ++++++++
Because it works. Also, go and print a fitting fanduct to that, with not that much 90° bends. Or even no 90° bends. Please.

++++++++ Why switch everything to 24V? ++++++++
Less amps in the system; only half of the current with using 12V.
I just personally like that more.

++++++++ Why switching to a Duet? ++++++++
There is no real reason to do so. For a 24V conversion i couldnt use the original board, but thats not the reason. The reason being i was looking for an easy manageable solution over all 5 of my printers, and Duet won that.
To be absolutely clear here, a Duet wont push your quality or speed. You wont see insane speeds on an ender 2, and an 8-Bit board will still be fine.
That said, if youre doing the 24V conversion, you could also look into using an SKR v1.3 Board with TMC 2208/2209s. That would also make a very nice and silent printer, and wont cost an arm and a leg. (because i went with Duet Maestro clones. Still a SKR v1.3 with tmc´s is cheaper, and youre only missing out on the WebControl if you dont use Octopi)

++++++++ Why the setup with the spool in the front, and board in the back? ++++++++
I like a small footprint, but also dislike a spool on top of the printer (because of vibrations, especially if youre printing higher).
So i came up with that solution, and it really functions nice.

++++++++ What will that all cost me? ++++++++

++ Stage 1: ++

12V 150x230 Heatbed 13€
350mm black 2040 Extrusion for Y 12€
plasmacut Y-Carriage (depends on your location; but around 20€)
a borosilicate glassbed in 150x230 12€
So thats a whopping 57€ ($65 or £52)

++ Stage 2: ++

24V 150x230 Heatbed 13€
350mm black 2040 Extrusion for Y 12€
plasmacut Y-Carriage (depends on your location; but around 20€)
a borosilicate glassbed in 150x230 12€
24V Ender 3 PSU 25€
Trianglelab E3D V6 Hotend 16€
5015 24V Pengda blower style fan 2€
Mobius 3 parts ~25€
FYSETC Duet Maestro 70€
Sunon 4020 24V 5€
And thats a whopping 200€ ($225 or £180).
Thats nearly two Ender 2. Or... what i paid for two Ender 2. Really.

++++++++ Is Stage 2 worth it? ++++++++
What? Hell no!
3D Printing is a hobby, and rebuilding or "reboot"ing (who came up with that idiotic phrase anyway... oh, that was me...) a 3D printer is a money sink.
If you want a bigger printer for cheap, go Ender 3! Or 5! Or... i dont know.

If somebody even cares, comment! And thanks for even reading until here!
