Building me an EZ-belt DIY printer for long objects

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.

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.

5 free printable stl files for original tabletop tealight holders

In this version, the tea light holder has a lower open spherical shape so that it can be used with a regular wax tea light.

Further down are the 4 versions of the straight flared tea light holder that are also well suited for use with a tea light.

Of course, an electric tea light is also very suitable for use with these designs.

[ NB: A design for a holder for an electric tea light with a higher inward-facing rim is in the other article. That version is not suitable for a tea light with a flame, because a flame can distort the higher, more inward edge.]

Print these STL files on a  suitable 3d-printer with heat-resistant,  fairly transparant filament for best effect!

This holder for an electric tea light with a top higher inward edge is not suitable for a tea light with a flame because a flame can distort the higher, more inward edge and may cause a fire hazard.

Dual magnetic parking extruders I3 Bear Duet2wifi build and Config files

My dual carriage I3-bear based 3d printer is working very well.

On this page I share my latest configuration files, my build experiences like the used STL’s , schematics and so on. 

Hope you enjoy!

Be aware that the tool settings in config.g are set including relative X, Y, Z values for this build so DO NOT put this in your slicer! 

And- you need at least RRF3.3.1 for reprap FW and for DWC. 

The sensorless homimg also requires knowledge of config settings and the good news is that the Duet2wifi has this all managed by the reprap firmware.  No switches needed or complex jumper settings!

Tip for printing the parts: I used ABS for all parts. Use at least a printer with calibrated XYZ values for your specific filament. 

Do a testcube first and apply any needed adjusting to your slicer’s settings like pre-shrinking settings of the endresult and so on. 

If you don’t do this, then don’t start this build. 

It is a prerequisite to get the magnetic carriage to deliver-and get the carriages from left and right of the X-axis. 

Therefore the movement needs to be free of unneccessary friction. 

And– if you use sensorless homing any additional friction on any sensorless homed axis might lead to unintended stalls.

I added a dripstop to the left and right hand sided X-carriages, made of some thin tinned plate.

It is positioned so, that a little tension is put on the nozzle tip in the parking position. It really works very well!
