Convert 6040z mks4-v controller to AXBB-E any help ?

[gurusonwheels]

im trying to convert a control box from chinacnczone to use the AXBB-E controller .

it has the mks4-v in it now .
here is a few photos inside .

any idea what all needs to be done ?

[gurusonwheels]

no one know anything ?
guess ill have to return the axbb-e as i have no idea weather to just switch boards and match wires to same places .
or if there is much more involved .

my existing setup works . i just hate mach3 ....

You'll need to do a little home work with your control box and whats in it.

What is the power supply voltage that goes to the mks4-v board? Is it 5 volts, 12, 24? You'll have to determine if you need a different supply voltage to power the AXBB (24v ) than what may already be there. IF your current board is 5v or 12 v, maybe you'll find using a UC300eth (5v) or UC400eth (12 v) is easier to install and wire without needing another power supply.


Look at the diagram on the AXBB webpage ( http://www.cncdrive.com/AXBB.html) for 'example' wiring.

You obviously have 3 stepper drives, each drive has a common, step, and dir input required. While your mks4 board has specific 'spots' for each axis drive that aren't user select-able, the AXBB (or UC300 or UC400) do not have any specific required spots to wire to these to, you set that all up in the software (port/pin selection, like Mach3). Same goes for spindle, limit switches, etc).

Any of the CNC drive controls could replace that board you have now, but I think the voltage you have to supply the board might be first hurdle to figure out, then determine if you want the AXBB, or a UC300/400 with a breakout board.

here is manual .
not sure if its saying it has a 10v power supply or a 24v and 10v....

There's no problem with the AXBB-E: it needs 5V for the logic side and 24V on the controlled side. The 24V can be 5V to 24V, depending on your needs.

Reading the PDF you linked, it turns out that the MKS needs no power supply: it uses only the 5V from the USB. It generates the controlled side power with a DC-DC converter.

To replace the MKS the AXBB-E seems to be the best choice, but you need the 5V supply and another for a higher voltage. The photos are so low resolution that I can hardly see anything on them. Can you take some useable photos? And also, open the lid on the VFD to see those cables too. Are the limit sensors simple micro switches?

(I can't see if the red cable is connected to the 5V output, where the 4th axis' cable goes, etc.)

well i unbolted the existing board so i could see where the 4th axis was going and this is what i see .

seems 4th axes goes into this box and this box is supplied 24volt from the internal power supply .
the other side of the box goes to the mks board where one of the wires is connected to a port marked +5v
shown here

tested the internal power supply the grey box it supply's 24.5vdc .

here is the VFD with the lid off

here is one of the stepper drivers .

the limit switches are just micro switches .
6 switches in total i believe .

This covered 'box' under your current control board must be your 4th axis stepper driver.

So you have 4 sets of 3 wires to each stepper driver, a +5 (red), and step or pulse (black), and a direction (yellow). These will all be easy for you to transfer to your AXBB when you get it. All of it will work fine, start labeling your wires for what is what as you unhook and transfer.
Just look at the board, the labels make sense (from your second picture):
A-D-: A axis Direction
A-P-: A axis Pulse (or step)
+5: the +5v common for making the step and direction work on the steper driver.

Then, for each other axis, you exchange the 'A' for 'X', 'Y', and 'Z'. This will get the 'movement' portion of your machine transferred to the AXBB.

What about the VFD
