I’m having trouble understanding when a change is needed for custom materials for example, when would you slow the speed of the laser down?
I’ve noticed when cutting EVA foam speed 500/power 80 will cut all the way through but also speed 140/power 1 and 2 passes will also do it.
Is there a rule of thumb for when to change speed, power, or amount of passes? I’ve wasted so much foam, acrylic, vellum, and cardstock trying to figure this out.
How does speed/power/passes affect a print? Right now I’m just picking random numbers and cutting stuff until something works but have no idea how to make the lines cleaner or cut through all the way on thick materials.
Can someone please explain to me or link me to where this has already been answered?
Please explain in noob terms. haha
Some Material Settings I’ve tested that work for me
- Felt | 0.3 thickness, 1% power, 140 speed, 2 passes
- Printer Paper | cut = 0.1 thickness, 500 speed, 20 power | score = 500 speed, 4 power
- Vellum | cut = 0.1 thickness, 500 speed, 30 power | score = 500 speed, 6 power
- 1mm EVA craft Foam | cut = .04 thickness, 140 speed, 3 power, 2 passes
- Thick scrapbook glitter paper | cut = 500 speed, 60 power | score = 500 speed, 12 power
So far I’ve noticed you need multiple passes on craft foam/felt/maybe all materials that melt down, once to melt it, two to burn away the melted stuff?
If you lower the speed, also lower the power dramatically?
I have no idea if the two above are correct
