I am working on Automatic Soldering Machine..For this i decided to use PROTEL AUTOTRAX as a CAD CAM Software which gives G codes for pads only.After that i decided to use MACH 3 to convert G code into pulses which is required to move Stepper Motor.The MACH3 send out the pulses to Stepper Motor vai Parallel Port.
Now i am not able to decide which controller should i use to interface between Parallel port and Stepper Motor.And also what shoud be the step size,voltage rating of stepper motor so that it van bear the load of soldering iron which is mounted as a pointer alomg Z-axis.
