i finally figured out what is wrong , i am blind
tape was inserted opposite way …grrr
now all axis work fine i can jog them but cant run job
i draw something in inkscape save like svg and load in laserweb run gcode generator and position drawing at 1st square in 50x50 and press job run and nothing move ,laser test fire wont shot from software
lb or lw 4 same … when i press on button it shoot 100% 28ma
Sounds like the pwm wire is loose. Test the connection and the LO volt levels when issuing a M3 or 4 for laser on and M5 for laser off.
Cheers
