Hi everyone!

Having some problem with setting my Duetwifi Laser engraver... can anyone give me some pointers?

• laser is connected to a mosfet then put on Fan 0
• laser can fire on S106 S0 (The on/off is inverse)
• I can home X and Y... but there is No Z... how can I set it up without Z?
• What is a good software to make gcode? I am trying to use lightburn, but seems it doesn't work yet?? (maybe because there is no Z)
  Any help is really appreciated! thanks!

Dear Dc42,

Thanks! I have added M452 and now G1 S255 xxxxxx will turn on while cutting..
It is still connect to Fan0 Port

M106 P0 S255 I1 H-1 ; Set fan 0 value, PWM signal inversion and frequency. Thermostatic control is turned off

M452 P20 R255 F200 ; switch to laser mode using the Fan0 (20pin logical port) output pins to control the laser

I have a few questions:

1. How to do I know the appropriate pwm frequencies? (F200?)
2. I noticed that on lower G1 S# xxxx that the laser is not turn on? (or so weak I cannot see any etches at all?) is there a min # to set? is it set on M106 Lxx??
3. any pointers to have a good etch? as I see some areas have very light and some are charred

Reinstalled Inkscape again and used @keyz182 's extension and it worked!

Here is the result of last night's test (ignore the previous burn marks on the left corners)
