The alu profiles are 20x20 mm.
The total dimension of the cube is 400x400x400 mm

This is correct, but it means the horizontal profiles are 360 mm long and the vertical 400 mm
Maybe it is a good idea to have a look at the assembly file: RepRap-XY.step in the step folder in github: [github.com]

Hi Guys,

What size of the straps of the x-axis and Y and width of them? Should I use pulleys GT2 with 20 teeth?

I have mounted the min-endstop for the x-axis on the leftside off the x-carrigae.
The y-min endstop is mounted on the front on the left hand side y-smooth-rod.
Home position is on the front left off the heatbed.

Thanks for reply, im not yet start printing all the files yet and just starting ordering some parts yesterday.
I really like this design cause all the parts is inside the frame. Do you already complete building your machine?

It is all printed with ABS. No modifications were made after the completion.
I am now designing a new one with a 300x300 heatbed and 300 mm in the z-direction, two(or three)belt driven leadscrews, linear guides,Dual extruder(chimera).Outher dimensions will be 500x500x500 mm.

Have any of you shared your cad files at all? I'd like to build a custom version but it would be great to not stay from scratch as my cad ability is lacking right now.

The 2 motor above the spool is extruder motor?

And with the build you already complete now do you have any problem with only 1 z axis lead screw to move the bed?

gforce1,

Nice job.
How did you build the frame? Did you tap the ends or use L shaped brackets?
Are you happy with your choice?

Thanks.

Can i know the dimension aluminum profile that you use for the bed holder, on the file it was 3d printed, and do you change all the z axis printed parts to use the aluminum profile?
