Hello.
I've recently purchased a laser engraving machine. The machine uses a Leetro MPC6515 controller (http://leetro.com/english/leetro_we...r&c=mpc6515).
The software they gave to use this machine is a bit old and really buggy. So I'm trying to build my own software to control the laser but I've hit a dead end... right at the beginning.
They have a small manual that supposedly says how to communicate with the controller.
The controller uses the Modbus RTU protocol.
If anyone cares to take a look at the communication info in the manual, you can find it here http://leetro.com/english/leetro_do...20%20Manual.pdf
What I basically need to know, is what information to send to the controller so that I can at least move the laser to the left.
If anyone can help me I would be grateful.
