CNC is doing everything backward
« on: August 11, 2018, 02:31:40 PM »
Hi Everyone,

I ran into a problem with my first project. I made a sign but when it finished the sign is a mirror image. Instead of left to right it did right to left but the sign came out as if I am looking into a mirror. What do I need to do in Mach3 software to fix this

Hi.
you need to reverse the direction of the axes concerned.

Sounds like the X axis is backwards. Go to Config/Ports and Pins/Motor Outputs and check (or uncheck) <step active low> and hit <apply>
and try again.

Note this will reverse the homing direction if you have set it. Beware if you hit <Ref All>, the X axis may take off backwards.

Hi,
apologies, I just noticed a bad mistake with my previous post, I said:

check (or uncheck) <step active low> and hit <apply>

That should be <direction active low> and hit <apply>. I don't think changing the step direction will do any harm but it won't
reverse the direction of the axis.
