I usually build my own 3d printers, usually based on existing designs.
The reason is that I just find it more fun in doing so.
So- I had a reason to get a printer that can print more lengtier objects than 350 millimeter, which is what I am now limited to.
After some research, I found 2 real alternatives.
The one is the Creality CR-30:
And the other is the Ideaformer IR3 V1:
Through my research I found that the Ideaformer originates from an EZ-belt open source design. Although the Ideaformer is a core XY printer and the Ender EZ belt re-uses the Z- and X-axes rollers on the EZ belt’s Y and X axes.
The EZ belt has become my choice for this build, anyway for the z-Bed.
I may initially start with the Ender setup for the XY extruder movement, but a coreXY may also be nice to have!
The Opensource Ender EZ Belt is originally based on an Ender3 pro, BUT I will build mine from scratch, since I have already rebuilt my Ender3 into something else and I am very happy with it. (Parallel Z-drives with top belt, direct drive extruder, upgraded 32 bits board, upgraded PSU, connected to MMU2 and so on.
DOWNLOAD the printed parts for the Ender EZ-belt HERE: ender-ez-belt-3d-printer-conversion-model_files
So- I am now in the process of sourcing the components and 3d printing the required parts!
All of the hardware like frame parts, X-axis side plates, extruder, hotend, motherboard, steppers, teethed wheels and -belts, bearings, nuts and bolts are available in my shop.
I will go with a Duet2wifi board, since this is known to me and I like the Duet’s web interface a lot. An ESP32 camera will be added to the build and this will also be integrated into the Duet’s Web interface, as with all my other printers.
As with my rebuilt Ender3, I will move the Power Supply from the side to a plave UNDER the printer, behind the motherboard which will be in the same place as with the Ender 3, also under the heated bed.
TO BE SOURCED:
I will need to source a good 24V PSU but I may go with an external one for this build, to start with.
Both the required 8mm rods will be sourced as well (1x340mm and 1x 240mm) .
The belt and corresponding heated have veen ordered from Ali, I chose an Ideaformer belt , 320mm wide, 1.3 mm thick and a perimeter of 1180mm.
