FAQs / parallel port to serial
« on: July 08, 2019, 02:03:59 PM »
Hi,
I recently bought a cnc engraver( 3 axis's ). It is a Chinese machine, Suda SD3025SXH.
It only has a serial port on the back of the machine and looks like it is only using 4 pins from the Serial Port.
I installed Mach3 on a PC and can get voltage on/off on pins 2,3 and 4.
I was thinking of using the parallel port on the PC and connecting to the serial port on machine.
Anyone ever done this or am I wasting my time?
If possible - how do I go about figuring out the pin layout on machine?
Any advice appreciated.
Thanks,
Paul
