Axis Parameters - Cnts/inch

[cyprian21]

Hi there,

In the Tool Setup Screen, in the Axis Parameters section, I'm noticing that when change the value for both X and Y by the same amount, the X & Y in the DRO are not showing the same newly updated distance.

For example, I first zero the DRO so that X and Y show 0. I then go into Axis Parameters and update both the X and Y to a new value, say 10300. When I look at the DRO I see that the X took on the distance change but the Y didn't, it only changed by 0.0007".

I'm I misunderstanding something?

Thank you in advance!
Cyprian

Hi Cyprian,

I think that makes sense. For example say your machine is at X=1.0 and Y=2.0 and you “zero” both axes. This actually creates an offset of -1 and -2 such that the GCode position reads 0,0. Now say the resolution is halved such that the current machine position becomes X=2 Y=4. So now with those same offsets the GCode position reads 1, 2.

Hi Tom,

Oh I see so it has to do with machine coordinates affecting the DRO. When I home the machine and we start are machine coordinates 0,0,0 and we also zero the DRO so it too reads 0,0,0, now when I move say 2" in both X and Y and proceed to make a resolution change the X and Y on the DRO now match each other.

Thanks,
Cyprian
