My sizes are out

[Desertboy]

It depends on the controller and whether it looks at the rising or falling edge.

However it's easy to test. Just write some G-code that moves back n forth few hundred short moves, say 10mm, then back to zero. If you have the wrong edge set it will lose a step for every direction change and it won't return to zero. Do this for each axis separately.

OK I drilled a small hole just outside my normal machining area set that as X&Y 0

then created code to
G01 X10
G01 X0

1000 times doesn't seem to have shifted

just running the Y code now

Will try Z after that.

Can I do something similar to see if I'm losing steps?

Or is there some test code for that?

In the manual there's "Level of Axis pulse signal" what does this mean? Is that the rising/falling edge?
