z axis direction question.

[ljoe1969]

the way my cnc table is designed the x and y axis both go in the positive direction when i tell the program (turbocnc) to jog in the positive + dricetion.

my problem is when i tell the z axis to jog in the positive direction ( i have the motor mounted on top of the axis )in the program, it actually goes in the opposite direction on my cnc table.

by default the motors turn clockwise when told to jog in the + direction.

how do i set the parameters in turbocnc so that the motor turns counter clockwise when it is told to jog in the positive direction instead of clockwise?

i am using a xylotex 3 axis driver and the motors that came with it.

You can also swap motor leads to make them go the other direction.

I'm going from memory here, but you can change the direction within the software. I believe it's the line "LowIsPositive=True", just change the true to false and the steppers will go the opposite direction. If it's not this line, then it's "IsActiveLow=True". I'm at work right now and can't tell you which line it is for sure, but I had to do the same thing on my machine.

Is it only the wrong direction when you jog? Or does it go in the wrong direction while running g code as well? If both, change it in the software as mentioned above.
