SKR Pro firmware for diode laser and Lightburn

Software / Firmware General
1

I have a laser hooked up to my LR3 using a BTT SKR Pro v1.2. I can get the laser working, running from Lightburn, but only with the “M03 / M05” laser control command option, and not with the “Inline” option as discussed in other topics. When I turn the “Inline” option on, the laser will not fire. Lightburn states that “This requires Marlin 2.0 firmware with LASER_POWER_INLINE set at compile time”, but I can’t find this line in the SKR Pro firmware source code.
The laser does work in M03 / M05 mode, but I’m getting issues (as can be seen in the picture) when carrying out fill commands. I suspect this is due to Inline mode not being used.

OK. Everything sorted, with the addition of the command M3 I inserted at the start of every file.
