I have a new used CNC Router that I am upgrading with a PMDX-422 Controller. I am holding of ordering Mach4 until I have the computer to install it on. Right now, I am torn on building a Dedicated PC vs a Laptop or Touchscreen Tablet to utilize with this machine. I understand that with Parallel Port, that timing was critical, and therefore Dedicated PC's are recommended. Since Mach4 is not using a Parallel Port and has been redesigned from the ground up, is there any known issues with utilizing a off the shelf new Laptop or Tablet. Of course Power save functions would be disabled.
In addition, I have another machine that I would like to upgrade in the future that is located in a different location, and would like to move the computer from machine to machine as I need. I don't envision ever running both machines at the same time and don't want to invest in setting up another computer for it.
