OK, I guess I glossed over that part. I think he was just demonstrating that one draw back of a dove tail bit. I wouldn't characterize it in general that it is easy to make a mistake with the SO. Like any tool you have to pay attention. The SO has a 1/2" margin of error where it will self correct. It is, at leas IMO, very easy to stay within that corrective range.
Thanks John. Yeah, I can see that now and understand at least what was shown in the video. Also thanks for your feedback on using the SO as well. Not owning an SO yet I was trying to understand its strengths and weaknesses and your comments help. I understand why they designed it to auto raise the bit on an error and normally that is a good practice for any CNC, I guess, but in this case with a dovetail bit it could cause quite a bit of removal as the bit lifts. It wasn't clear to me in the video whether this was a legitimate error that he made and showed on video, OR was it purposely done to illustrate the point of what
could happen. He did say feed rate can cause it to do this, i.e. if you go too fast with the SO and that is more likely the kind of mistake that an inexperienced user like myself might make with an SO until I learn the tool well enough. Still this might be a freak occurrence.
