Ok guys I bought a plasma that was running the microkinetics system and I am in the process of upgrading to Mach 3 through a cheap sain-smart 5 axis breakout board I bought off Amazon. The problem I am having is i can't get the high low signals out of the PC into the board. I have managed to make two motors run properly but one is on a different port of the board. For example the x axis is wired to the z portion of the board and the y is on the y axis of the board. Both motors are working but i know it isn't right as i have 5 volts on most of the pins on the breakout board all the time. On the pins i have the motors wired to both have 5v on the step and direction pins at the same time. When I press the left arrow for example the voltage stays at 5v while it turns one direction. When I reverse direction motor shows 5v the slowly drops down but returns as soon as you release the key. I watched a youtube video with a guy showing how to check the parallel port with a meter but all I can't get is 3.3 volts vs the 4.3 he was getting on all pins 2-9 on the pc. No high low swing nothing changes when I press the arrows to move the machine. Any ideas what I can do to get this board working properly?? Thanks!
