I'm amazed 20% power @1000mm/min is probably too much power.
Here I'm showing 5mm hardwood cut in 1 pass 1000mm/min @ 20% power with Lasertree K30 30Watt Diode laser module.
I have some really useful modifications for the GRBL controlled CNC3018, I'm considering selling these on my store, if you're interested message me!
please subscribe to help me get my views up!
thank you!
