Hi,
We just got a RS3040A laser machine from Redsail, (hflaser.com). Everything we have engraved is ok so far. However, we are trying to engrave on colored anodized aluminum and it does not engrave anything, we set the machine to min. speed and max. power and it does not even scratch the color layer.
The machine is 40 W power, from what I know it should engrave or is there any trick I´m missing?
Thank you,
Jose
