Hi all,

Looking into purchasing one of these pneumatic syringe pumps to use as an extruder for a 3D printer:

Nordson EFD | Ultimus

Ideally this syringe would be mounted on my Syil X4 mill and used as a hybrid 3D printer extruder. I would like to connect the pump to Mach3 so that everything can be controlled simultaneously with the same code. I was thinking of using the coolant commands (M7/M8/M9) to control turning the pump on and off. There are two kinds of connections from this pump to the PC: RS232 and 15-pin I/O. Any ideas as to how to control this system from Mach3?

I have little to no experience with electrical wiring and limited experience with Mach3 so please be thorough in your response if you can.

Thanks,

Josh
