Reporting my findings. New controller arrived along with a new torch so installed everything just fine until I tried to calibrate the new torch with the new controller plus
All seemed fine but at computing results it would always give a BAD calibration error of around 1.0. I redid the tests three times. Same result.
I then plugged in the original controller and did the calibration and it passed first time error of approx 0.5
i did notice the numbers were different for each controller New would be 19-24 and on original it would be 18.5-20. everything else was the same. The shuttle had no play. Triangle clamped.
My old torch clamping diameter was 33mm new torch is 40mm. if that has anything to do with it.
