Welcome to the CNC ride hold on tight, keep arms and legs out of the machine at all times...Lol

Just post in machine discussions if you're unsure but don't worry about it if, in the wrong place, no one will get upset about it.

My suggestion is you start a thread in machine builds, even though you are not technically building a machine, describing the machine, and ask all your questions related to it there, this way you are not starting loads of threads asking just a single question, also all replies to your questions are in one place and easy to find at a later date.
