C Axis calibrating (for aggregates)
Greetings,
I have a 4 axis machine wherein, a motorized "C Axis" rotates my aggregates around the Z axis so I can cut with a saw aggregate along X or Y or anywhere in between. It's an HSD unit, "Axis MK250" to be exact. Rotating it to 0 (of 360) is part of the home operation.
I had reason to believe that it was not properly calibrated because my saw kerf measured 4.5mm rather than 3.2 mm which is the actual saw kerf spec. When I used dial indicators to determine if it was off I found that the C is about 1.3 deg from 0 on two different Aggregates.
My question is; does anyone know how to adjust the "C axis sensor" that tells it when to stop rotating at 0 when it's homing? Or even where it's located? Alternatively, how can I do it through the software so that this 1.3 degrees is compensated?
Thanks

What is your CNC controller brand and model name?
Have you tried to go back to the reference point (return home operation) ?

The controler is LNC 2000 I think. The machine is a Style CNC
Yes, even after Homing, the C axis is off 1.3 degrees. This is true with a Saw aggregate. I know this because when I saw at 0 the kerf is 4.5mm or so. When I saw at -1.3 degrees (88.7) the kerf is 3.4 (supposed to be 3.2mm) and increasing or decreasing the deflection only increases the kerf. I measured another 90 degree tool and it reads at least 1 deg off.
