My S3 came Friday and I got it all put together before going to bed. Saturday morning, I started testing, etc. and there are a few things I discovered that really should be fixed in the documentation.
Number 1: where is "lower left?" Well, I made the assumption that "lower left" (as stated in the Hello World docs) would be the home location. It is not. Lower left is the opposite corner from Home. That simple thing would have saved me some anguish and looking to make sure I hadn't put the connections upside down.
Number 2: The limit switch setup simply doesn't work as described. The instructions say to enter $22=1 and then do a $h and it will start going through the home sequence. Afterwards, it says, go into settings and change False to True. That did not work for me. When I sent $h, absolutely nothing happened. It was only by accident that I discovered that after you do $h, you need to go to settings and make the False to True change, then go back to MDI and enter $h.
Number 3: (and this goes along with number 1) During the build, it was sometimes difficult to understand which direction was being referenced. Is right as looking at the machine or is right really starboard?
Otherwise, I am so far very pleased with the build. I haven't had a chance to make any firewood yet (historically, the ultimate destination for a lot of my woodwork), but maybe today.
