Ashleigh,
If someone has that machine and it's associated software then someone may offer to help you.
This forum covers a lot of general topics but it is mainly about using Mach 3 as the controlling software.
Your "system" is made up of a PC with has a contolling program ( ie; given a set of instructions it will send signals to the motors
so they create movement of the axis). Additionaly there is probably a engraving program which generates the code / instructions to be given to the controlling program and once recieved it will execute those instructions. SO the controlling program must be set up to move the axis properly and then you need to learn how to use the engraving software.
So start reading the manuals. If you don't understand your controllng program or the other software to some level you will never run the machine properly.
If you post info on it maybe someone will read up on it and can assist in specifics.
If I was your boss, I woud have included in the purchase tech support or some training for using the machine.
But cheapo's that they are today, they just dump something on someone and magicaly expect things to happen.
My boss...heck bosses .....know i have a FM key on the keyboard ....so they request ...and i just press the key....
and so it is done.
