I had 2 boards working with my 2 good pic's.. replaced the bad one. Tried to put my breakout board (non OPTO) in place. NOTHING works. I can see the step and direction signal come from the breakout board to the picstep. If I short S1 on the breakout board I get 2 of the led (2 led wired opposite with a resistor to limit current)to dimly light. tried 3 board 4 pic's same issues.
I have also removed the breakout board and wired
parallel pin 2 to picstep pin 7
parallel pin 3 to picstep pin 8
5v to picstep pin 1
gnd to picstep pin 10
gnd parallel pin 22
same thing is seen on output.
thought I was on a roll after the laser printer pc board etching worked so well.... but all has gone rapidly downhill from there,
