Its like my laser runs out of steam…
I did about 5 x 3cm circle tests on a new piece of 3mm bamboo ply - found out the following settings were the best: 4 passes, 240mm, 25.5 height (as i now use a bed of nails instead of the silicone mat). The circle cut really well and slid out with only one tiny piece catching. So I thought this was the best setting to follow. I then tried those settings on a bigger scale - just to cut lots of shapes. But i made the mistake of moving my piece of ply after the job without checking first… NOTHING had cut through (I pushed some through and it was a mess!). I did the job again with fewer shapes and carefully checked to see if it needed more passes when the job was done. After the first 4 at 240mm, I did 2 more at 220 and then one last one at 200… 7 passes and it barely cut through.
Why when doing a bigger job do the settings differ to my test? Same piece of ply.
*I don’t think my air assist is working properly - could this be causing such extreme results?
I’ll attach some pics. Thanks in advance for your help! :)
