I'd like to buy a 3D printer and use it as a "platform" for an external optical sensor. The idea is to mount an optical sensor on the Z-axis and to put a workpiece on the X-Y table. Now, I'd like to move the sensor across the workpiece and trigger the measurement of the optical sensor. Hence, the 3D printer is not actually printing, but only used as a motion and trigger device for the optical sensors.
I have never used a 3D printer, but I'm afraid that I'll run into several problems:
- The standard G-code of "wait one second" is
G04 X1on many CNC machines. Does this code exist on 3D printers as well?
- Is it possible to extract a trigger signal (e.g. 5 V) from the 3D printer? Are printers available which provide a G-code for an external trigger? Could anybody suggest a model? I'm happy to pay some extra dollars if I don't have to solder by myself. Of course, a second option would be to use the voltage, which is used to heat the filament.
