how to change axis orientation

[drobbins]

Hi Folks

this should be an easy one
newbie here, I've built a cnc wood router and I'm controlling it with Mach3
when I jog the machine with the right arrow key on the keyboard is moves left
how do I change this?
it seems like with my original setup the coordinate system is messed up
I'm sure you fix it with software settings but not quite sure what to change

TIA for advice
Dave

Config>Homing/Limits. Check the "Reverse" column for the X axis.

ok, progress
now I press the right arrow key and it moves right
but the digital readout counts down when it should count up
how do I change that?
don't worry, I'll get it straight

TIA

Which way is Y+? Towards you, or away from you?

At the moment I'm playing with the X axis
I assume others would work the same
It's a gantry style router and the X axis is moving the gantry left and right
my first question was how to make the gantry physically move the correct direction when I press the right arrow key
I'm using stepper motors to run the machine so it's changing the step direction signal, we already solved that
my question now is how to make the DRO value change in the proper direction
it currently decreases in value when it should increase
I know this is just all software configuration stuff, just couldn't figure it out from the docs
thanks for the help, hope my explanation is clear

edit: read your post again
I'm playing with the x, positive should be to the right
y+ should be moving away from me and z+ should be up
that gives a right handed coordinate system

Did you change the jogging hotkeys? Go to Config>System Hotkeys and see if X+ is set to 39?

I'd just flip the "DIR low active" checkbox in the motor outputs. Then your DRO should count up and your axis should move the other way.

thanks folks
I've got everything working right now
