Mark, if you use the hard stops, then force the trunion to go beyond the limits, the system will disable. ?I did this a few months ago, forcing the trunion to minus 1 degree, and it hit the stop and refused to tilt in any direction from there. ? Once the system faults like that, you have to manually apply 24V power to the positioning motor to drive it off the hard stop. ?Once that¡¯s done and the machine power cycled, ?it¡¯s fine again. ?I was able to do this using a 18V battery from one of my cordless drills, but it was certainly a PITA. ?You might ask why I got in this situation to begin with, and it was a simple keying error when I was calibrating the 0¡ã stop. ?

Thanks guys, what about the other angles 11,2¡ã; 22,5¡ã; 33,7¡ã? I know about checking the 0 and 90. They Also told me not to adjust the hard stops which makes no sense to me, the encoder motors we use at work utilize hard stops, we don¡¯t like to rely on the software for that

Thanks David,
Like you and Lucky described, I do the cut test to confirm calibration. I calibrate with precision 90 & 45 squares.
I am just curious what my wixey angle gauge does. If memory serves me right if I zero it on the table it shows 0 or 90 depending upon which side I use on the blade.
I do not like using digital angle gauge for calibration because, well it is digital; you do not know when it is going to flip plus it does have repeatability error.

For the 90¡ã stop, I cross cut a 1x3 on edge with the blade fully up, flip the off-cut over, put the two pieces back together on the bench and check with a straight edge. ?Same method with a 1 x 3 at 45 and check for square.

I guess i will need to check my angle gauge now. I did not use it to calibrate 90 & 45 stops on the saw though.

I¡¯m with Lucky on this one. ?I have not found that the digital angle indicators produce very accurate results when used the set the angle stops on the saw trunion.

Hi Mark:
When calibrating my Kappa, I tried the tilt box method and was surprised how inaccurate it was for me. Maybe the fact that the tilt box is not accurate enough, or maybe the fact that a saw blade body is not necessary ground flat, or a combo?
For me, making test cuts in timber and measuring the results yielded the best calibration. 90 degree cuts in two thickish pieces, butt together and check with a straight edge. 45 degree cuts and then check for square.?
I¡¯d be interested in whether the tilt box works for you. Cheers.?

I have the procedure, is a digital tilt box accurate enough or am I better of using a vernier scale protractor like the Mitutoyo 187-201. Looks like the tilt boxes are accurate within .2deg.
