I have the IR2 infrared laser working on the Sculpfun S6 machine. I am battling to find the correct settings in Lightburn to engrave on Stainless Steel. Any suggestions?
Not really. There are no general settings. Try slow speeds. The module has 2W, so maybe try 200 mm/min, 90% and check how it looks like. You might use cross-hatch for engravings, I found it to be beneficial on steel.
This is an official video but the settings are suggestions, so you may need to try it a bit.
Setting used are:
Stainless steel 1000 mm/m with an interval of 0.01 mm
2000 - 3000mm/m with interval of 0.02 / 0.03mm
for plastic 6000 mm/m and 0.03mm interval.
Now it is said that running at 100% may heat the diode too much, which wears it down. Not sure if that is also the case for the IR laser, but I would limit the power to 85% and slow the speed to resp 850, 1700, 2550 mm for the Stainless steel and 5100 for plastic.
I haven’t tried mine yet, but I was looking for some initial settings.
Have fun!
