Saabaero,
Good to hear that you have the TTS up and working. I think holding my breath will be less often with the TTS which is the main reason I bought it. The way I look at it, crash time would most likely only be the first time I enter the tool vs everytime I change one.
I plan to add a probe system and 4th axis as well once I get a better handle on all that I have been learning the past couple months. Not sure if Mach3 can do part setup with the probe but that is one thing that would be great to have. Also being able to use the probe to measure parts would be a neat feature as well as the tool setup advantage you mention.
Funny observation, likely we are the few lonely manual readers. That is based on my past experience in that few venture so far as to actually open a book! So many would rather just ask for a quick fix rather than understand and figure out all the millions of little details. For me that's part of the fun of this whole adventure!
Back to your issue.... I'll try to use the waterline process shortly as David sent me the IGS file of his router holder that I want to make. I think that would be a good part to give it a try on. First though I have a few small prototype parts to make for someone that has actual $'s to give me.
