Im new to maching and I figured the best way to learn is to buy a lathe and get started. The only way for me around here. I purchased a 6300 with a 3 phase motor. I have a vfd to operate from 220 to 3 phase. when powered the lathe turns very slowly for about a half inch and that's it. Any ideas as to what the problem could be or if Im operating it correctly. I am new to this.
