Lifting up Cutting material
Last weekend I needed about 15 passes at 1.8amps to cut a piece of Plywood (afaik it is 3mm, forgot to measure). Even after 15 passes it was not cut through all around because of the differences in the wood. I had to push the parts out of the wood and do some sanding of the edges that were not cut through.
In the meantime I put the laser-current to 2 Amps.
This evening, I did some experiments with cutting. I lifted up the Playwood by 3mm using cut-out pieces from experiments before. I think it cuts through better now and with a cleaner cut. About 8-10 passes are more than enough now to get the part falling out by itself.
I don't think this is all to the higher current, I also think it has to do with lifting the plywood up.
Has someone similar experiences?
Maybe I will do some verification tests next weekend. I'll keep you up to date.
