Diode laser on a LM Mk3

[_Michael]

I wonder if it’s related to this.

No power at laser output connector

Are you running the stock firmware? Awhile back I flashed grblHAL, built with the grblHAL web builder, to my SLB on my LongMill Mk1. Everything was working fine until I needed to use my laser. I couldn’t get it working and wanted to proceed with my project so I flashed it back to sienciHAL and my laser worked again. I don’t know if I missed something in the web builder configuration or the settings somewhere in gSender but I got it working pretty quickly when I switched back. My laser is 3rd …

Just to be clear I had built the firmware using Sienci’s LongMill Mk2 profile. Now there is a LM Mk3 profile on the Web Builder as well.
