I had a friend ask this when he went back to his CNC machine after years of not using it.? His PC is rather flakey probably due to power supply capacitors. ??But anyway it seems he has his axis mixed up for what Fusion360 generates for G Code.

?

What he told me was that if he presses the Right Arrow Key the X axis motor moves the table but the DRO on the screen increments on Y distance.

?

What has he done to cause that sort of screw-up?

Thanks

Sound like he plugged something in wrong.

Can’t see how Fusion or bad caps would swap an axis like that.?

?

Although… Fusion used to have the X & Z axis swapped (so X was up) until the CNC guys complained and now Z is up as it should be.? Check his Fusion preferences and redo the g-code?? (Very long shot!)

Thanks Tony,

He tells me the problem is now fixed.? He can't tell me how.? I'm suspecting that he had his XY motors crossed and _thought_ he was pressing the right arrow key when watching the Y DRO change.? He has a tendency to change things in a non-methodical way when he gets frustrated.

?

Sorry for the noise on the forum.? I really didn't think it was possible to change arrow button behavior in MACH3 but just in case I thought I'd ask.

Thanks.? I think the issue is regardless of what pins run what motor if you press the right arrow key to move the X axis that the Y axis DRO changes on the screen.? True if you switch the pins that are for the Y axis onto the X axis output in ports and pins then pressing the right arrow key will move the Y axis motor but since it's not a closed loop system reading steps back from an encoder connected to Y how would it ever change the Y DRO.

?

Unless there's something else in ports and pins that I'm missing.

?

I think my friend was just confused.? And did have the axis mixed up but thought he was pressing the right arrow when in fact he was pressing the up arrow.
