Which way is Z axis?

Software / Firmware SKR Boards

Just got my Skr Pro and TFT35 wired and everything moves nicely.

Maybe this is a dumb question but which way does the z-axis go? As z moves down is that more positive or negative? The down icon on the TFT35 shows a Z+ below it, so I’m assuming the larger Z is the lower the z-axis is.

The reason I ask is that all my motors are wired the same and they all move in the correct direct except Z. I put JST connectors on my motor cables so they are not easily flipped.

I solved the problem by using Settings->Features->Invert Z Axis. My question is this expected?

Thanks.

Z should be more positive the higher it goes. If that isn’t right, fixing it in the tft will do you no good.

If you can’t reverse the whole plug, you can also swap two wires. From: 1234 to 2134. JST aren’t as easy as dupont, but it is possible to get those out.
