Hey Guys, I've recently been trying to engrave on silicone straps/bands for Apple / Samsung watches. 

The problem I'm having is really poor results, and I've tried a huge number of settings by now. 

Either the engraving is not deep enough, or the edges become too soft or ‘melted’ with inconsistent patches across the band.  

I'm hoping someone else has had these  difficulties previously, and could guide me to some solutions? 

Thanks in advance!
