I have a wierd issue and thought someone may be able to shed some light on it. Using V1.2115 and using the built in circle probe routine.
I am 99.9999% sure it is not my touch probe .
In fusion 360 I setup to do a bore - say 22 mm and a contour finishing path with a 6mm endmill . I use this to reference for a tooling plate and my WCS is the centre of the bore .
So I move to WCS G54 X0Y0 and it does the bore and contour.
Now I load the touchprobe ensuring the runout is as good as I can achieve.
In theory when I probe that bore the centre should be at G54 X0Y0
but what I probe I get the following values when the connection cord aligned such that it is
Pointing to X+
X0.0375
Y-0.1275
Pointing to X-
X0.0475
Y-0.1300
Pointing to Y-
X0.0350
Y-0.1350
Pointing to Y+
X0.0400
Y-0.1250
And moving the lead each time to point to direction of probe
X0.0375
X-0.1250
Now I understand there will be some errors due to pretravel and concentricity but the consistant -0.1mm error on the X is a issue for repeatability.
I believe if there was a setup error or probe error it would move as the probe is rotated .
Below is a snippit of the start of the gcode
G3 X0. Y8. I-0.6 J0.
X-8. Y0. Z-0.192 I0. J-8.
X0. Y-8. Z-0.384 I8. J0.
X8. Y0. Z-0.576 I0. J8.
X0. Y8. Z-0.768 I-8. J0.
X-8. Y0. Z-0.96 I0. J-8.
X0. Y-8. Z-1.152 I8. J0.
X8. Y0. Z-1.344 I0.
To me that shows the circle cut on X0Y0
Backlash and settings have all been checked
I also did a manual check with a indicator and the actual bore centre is off X0.026 and Y-0.132
is this a Constant velocity issue or a error in the software or some sort of rounding issue.
