You might need to use a 4mm drill bit to make sure the carriage can go up and down freely with not friction but trying not to create excessive play between the rods and the sliding part.

Hi!more thanks for design and sharing! but i cann't understand one thing. vertical carbon fiber tubes must be free in which holes-holes of servo support part or in vertical carriage (which is like smile). when i put everything together, vertical carriage doesn't want to move down without help(i use several big nuts), but, i think, it's not the way out.

Hello, thanks or the design and sharing. I will need to build the machine for my BA project. I am very new to the 3d printig and aurdinio for not to make any mistakes can any one explain the lates and updated step to build. Thanks for all help.

Scale needs to be adapted to your build with $100 and $101 parameters in GRBL and so are acceleration and max travel on each axis too. For me $100=80 and $101=80 did the trick, but yours may need a different number of steps/mm.

Hi! thanks a lot for this build!it's really cool! I made it and faced problem. i put firmware from your link into Arduino and faced an issue. Steppers make huge moves. i tried move it with buttons in GCODE and insted of moving on 1mm it moved on about 20-25mm! could u please help with this issue? I use arduino uno, 17 nema steppers and drv8825 sticks

How does the firmware know if the movement should be corexy or XY?

Thanks Miguel.I could do this quite easily using SketchUp STL.

@Frg though my initial attempt at the CAD design was to make the model fully parametric, my lack of skills prevented that so I have not an straightforward way to create these parts for you. Still, as CAD model is available you can probably get it done. Please note once modeled in Onshape you can easily export it as STL.

Thanks.If I have 90 mm between rods , can you please send me STL files for the top and bottom center carriage .

60mm between rod's axis, 52mm is the shortest distance between rods. Please note Onshape CAD is linked above.

What is the distance between rods?

Very interesting project, about to build one myself. What is the length of the rods? Any assemble guidelines available?

Hello, We wanted to compile a virgin version but we could not make the connection to grbl control. We could not find where do we have the problem so, can you please send the compiled version to us?
