Laser Raster option generated the gcode with S value to small, 0.1 - 0.7, instead 10 - 70

Hello everyone,

First of all CONGRATULATIONS to all developers for this awesome software, I love the futures, and easy of use (after wathing a tutorial :smiley: )

I made a few engraves from an dxf file, came out quite nice, but now I wanted to test a sample raster photo, and the generated code seems to have the S parameter to small, the range is around 0.1 - 0.7. The light on the laser doesn’t turn on on such low Power settings.

I pasted a sample code the was generated, with the Min Power set to 50 and Max power set to 100:

G21         ; Set units to mm
G90         ; Absolute positioning

On my previous test, where I engraved with Power set to 10, the gcode looked like this:

G21         ; Set units to mm
G90         ; Absolute positioning
M4 S0       ; Enable Laser/Spindle (0 power)

Any ideea why the S is so low when I used the Laser Raster setting?

Thank you!

nobody around to give me some hints what I could tweak to have an usable gcode with my laser, cand someone else tell me if they ware able to use the engraving gcode, had the S parameter with values so low ? Did your laser controller handled the gcode with so low values for the S parameter ?

Thank you in advance
