RepRap version of Zelogik's core-XY 3D printer

This is the first release of a RepRap-XY 3D printer. It is based on the excellent design of Zelogik. See his github archive at: https://github.com/zelogik/AluXY

His design and my variant are discussed in the RepRap forum at:: http://forums.reprap.org/read.php?4,297740

When I saw this printer I thought, this is the printer I want. It has all the features I want in a printer:

• Based on the Core-XY system. (see http://corexy.com/theory.html)
• Frame made from aluminium extrusions.
• No motors, belts and guides on the outside of the frame.

It only has one problem for me, it is made from CNC-ed aluminium and I do not have access to a CNC machine. I decided to build a printer based on this design, but use printed parts instead of aluminium parts. That is what you will find here.

This is a work in progress, Use at your own risk.

I made one and it is working just fine. I did not yet make something for the X and Y endstops. A simple adjustable Z endstop exists and does the job for adjusting the first layer height.

The file src/RepRap-XY.FCStd is the complete assembly in FreeCAD format. The file src/RepRap-XY.vc3 is the complete assembly in VIACAD format.

The file build.py will mirror a few parts and generate the STEP and STL files. Just open the file in FreeCAD and run a a macro.

In the doc folder you will find a BOM. This BOM is not generated from the model but hand made, so be carefull You will not (yet?) find build instructions there. Have a look at the sourcefile RepRap-XY.FCStd (FreeCAD) and RepRap-XY.vc3 to see how everything fits together.

To see some videos of my printer have a look at my youtube channel: https://www.youtube.com/channel/UCOyTdQOCCLdy45FtSlam_3A/feed and some images at my imgur album: http://jand1122.imgur.com/

Have fun.

reprap-xy's Issues

What extruder are you using?

I spot you are using geared extruder. Which one should I print it out? Can I use MK7 ? Or E3D V6?

How ist the Z Axis fixed to the Printbed?

Im on my way of buildung your Printer design, and now stumbled upon the Problem, how the Z Axis is fixes to the printbed, and if it is easily interchangeable to Tr10x2 Leadscrews.

Looking Forward to hear from you,

Greetings from Germany

Z Axis

Hi, first of all, congratulations for you awesome work !!!!

I'm thinking fork you repo and do a few changes

do you know what will happens I try change 12 mm smooth bar by a 8mm smooth bar on Z Axis ?

(I have a 2 8mm smooth bar prepared for Z axis)

Thanks

Printer belt construction

Hi! I'm starting to build this printer and I'm having some problems to put the belts. I have read the forum but couldn't find a clear diagram about how to put the belts and how the tension system works. Would you mind taking a picture inside where the motors are mounted?

Z-Axis Assembly

Hi Jand,

I am in the process of building your version of this printer and I am not sure how the inside of where the leadscrew and the bed come together goes. In other words how do you keep both nuts in position in that little enclosure? Thanks for your help!

Chris

How do these belt clips hold? They seem not to have perpendicular traction on the belts.

Congrats on the project! I've seen the videos. It looks awesome!
