Just a quick update.

Board now mounted inside.

main power now split to drive the pump when switched on.

Screen added.

I have not connected a computer yet, all controls off the screen for now.

So. Power up and all looks ok, getting things on the screen.

Can jog about and change the step size.

I am sure that the Y axis is inverted and moving it Y- should bring it towards the front of the machine but it moves towards the back.

On setting it yo do a return to home it wants to move to the front left corner, not the back left.

is there a way to reverse the axis or have I put something in wrong??

Remove power. Flip the Y motor cable 180 degrees.

the 4 pin that goes into the board?

No, the smaller cable that is going to where it says “Y”. This is above the green motor driver board.
