Hi... sorry for my bad english.. I read this only now...

In MarlinKimbra in configuration_core.h you can set the moltiplicator for set 3:1 XZ..
/*****************************************************************************************
 ************************************* Core settings *************************************
 *****************************************************************************************
 * This define the moltiplicator axis from X to Y or Z in COREXY or COREXZ.              *
 * Example:                                                                              *
 * COREXY set COREX_YZ_FACTOR 1                                                          *
 * The result is:                                                                        *
 * X = dX + COREX_YZ_FACTOR * dY = dX + 1 * dY = dX + dY                                 *
 * Y = dX - COREX_YZ_FACTOR * dY = dX - 1 * dY = dX - dY                                 *
 * Z = dZ                                                                                *
 *                                                                                       *
 * COREXZ set COREX_YZ_FACTOR -3                                                         *
 * The result is:                                                                        *
 * X = dX + COREX_YZ_FACTOR * dZ = dX + -3 * dZ = dX - 3dZ                               *
 * Y = dY                                                                                *
 * Z = dX - COREX_YZ_FACTOR * dZ = dX - -3 * dZ = dX + 3dZ                               *

Hi, awesome job!
This design is incredible and i am also making it at school in spain for my students, i have clear the x and z part, now we are in holidays but i need help with the y part when we return to school, we dont understand how the bed connects to the y motor, to made the movement, we dont see it in the models of gitub, someone can explain it to me?

How only 1 motor in y ,can move it front and back with the same system of 625vvs
?

A paint or a explain will we much appreciated of if i need some extra hardware.
In the x and z part, i made the tension with screws and no guitar plugs.
Very thanks in advance

scottyorr posted an implementation on thingiverse, which includes video. That should explain how everything works

Hi I saw the video and still get the same question as some other, i think i the string need to attach to the bed at some position right ?
If you can draw a sketch similar to the one for XZ axis in page 1, it will be a great help
Thank you

Green things are grounded and blue things move in the Y direction.

Using repetier firmware 0.92, just need to add ; in 2 lines, if its error when compile.

Thx nicholas !

hi, can you tell me how do you implemented the firmware? what do you change for corex xz? i tried repitier firmware and marlin kimbra with same results...

i have a big problem, i made a setup like the original, compiled, but in repitier if i say that it moves to the left +10, it moves to the left and up at the same time! and if i say to the right, it moves right and down.... up and down in z , doesnt runs.... i dont know what is happening... some help will be aprecciated!
Re: CoreXZ - SmoothieBoard

Hi all,

I have a problem with the Core XZ on my Smoothieboard.

I used JNJ's method for connecting the motors as per below..

# arm_solution corexz # selects the corexz solution

# x_reduction 1.0 # standard CoreXZ has no reduction on x axis
# z_reduction 3.0 # standard CoreXZ has 3X reduction on z axis
# alpha_steps_per_mm 55 # xz motor 1
# beta_steps_per_mm 55 # xz motor 2
# gamma_steps_per_mm 110 # y axis motor[/i]

It all moves fine EXCEPT when I home the Y axis ... this makes the Z move..
I think this is because your alpha and beta motors become the X and Z axis.. hence the smoothie does not recognise the true Y axis?

Is it easy ( or how can I do it ) to make the xz motors the actual XZ motors on the smoothie?

Or do you have another solution for homing maybe?

Good night nicholas.seward I'm curious if you made modifications to the printer Core XZ, a nice project. Hugs.
Re: CoreXZ
November 15, 2016 03:04PM
@rsenas: I haven't changed much. I have switch two of my machines from a geared extruder to a direct extruder. Other than that, it works great.

The biggest negative of this printer is the resonance that happens when you turn corners due to all the stretch in the string. This could be solved with higher test string. For me, the problem is only cosmetic at higher speeds so I have no motivation to fix it.

It's good that the model does not have big changes. Thank you and great day.

Good morning MagoKimbra, could you inform me how to modify corexz to core xy? I want to place it on top of the printer in cube format and the z axis goes down. Thank you and I await. Hugs.

Would this work as Z=1:2, X=1:2 ?

I'amnot good at this:-P

Thanks Jesper

That is a great arrangement. It will work.

Okay maybe I will try it then.
Is it correct as 1:2 on both x and z?
Re: CoreXZ
July 05, 2017 11:17AM
You are correct but I would just use 1 for both and then use the steps/mm to calibrate. The ratio between the two is the real important number and yours is 1:1.
