very few tutorials. support sucks, very little activity in thier forum, 4th axis assignment to axis on part i still havent figured out after many hours and one tutorial the only on i could find on the net. i tryed to do exact same thing as tutorial and my newer version apparently doesnt work the same. i learned autocad very fast and can machine very complex parts on manual dro machines. they must have thier email filter on high because most ppl ive heard of say email support is very minimal if they get an answer at all. i called tormach where i purchased my machine they didnt seem to be able to help much. tormachs service is a1 and they ppl are great. i just wish they would be a little more clear about the fact if you are new to cam its going to be along hard road with lousy support.
