    Thank you!
  2. Re: Sheetcam Plsma. Post prosser requires Diameter.

    You should enter the kerf width as the diameter. In other words, the plasma flame itself has a diameter, and you can figure out it's size by measuring the width of a straight cut.

    Re: indexing

    A moving table will require more floor space than a gantry. It's easy to realign the sheet to make cuts that are larger than your machine. I would not bother with a moving table.

    how much more powerful is the pneumatic engraver compared to a plain ol' electric engraver?
