Are the rulers in your Speedy 300 metric or inches?
Because my machine was originally sent to Canada, then Brazil, the rulers are metric.
I prefer inches, so first I made one from a similar thickness of acrylic.
After engraving the acrylic, it bowed upwards.
The rulers are held down with screws and I could put additional 2 sided tape underneath to keep it flat however I used some fluorescent acrylic (the engraved numbers and lines light up from the internal lighting in the laser compartment) and I was thinking the tape might compromise that effect.
So then I thought, why not forget acrylic and just engrave the back side of the existing anodized aluminum rulers. OK so I removed the short one and engraved it but being so new to this, I probably made the wrong power and speed settings. By default for metal substrates, it wanted to use 100 power and 100 speed for engraving. I thought this was too high and so set it for 30 power and 80 speed. The thicker lines and the numbers engraved, but my hairlines did not engrave so I ran it again at 35 power and 70 speed. This helped a little but still no hairlines.
Another issue I notice is the right side of the ruler is not engraved as clearly or maybe I should say as deeply as the left side.
I had it placed to engrave horizontally from X= 0 to X= 17
What would you suggest to obtain the hairlines and a more uniform engraving across the entire ruler?
