Also replacement power suppy with built in fan ond ,when i get a chance next time i lots of cutting to do will measure power at diffrent temps,spent last 2 days cleaning/aligning/modifying laser cutter,air compressor and air dryer
i can now cut 6mm mfd at 18ma and 4mm/second
I haad a look at this guy here https://www.youtube.com/watch?v=kJe16YQlIM0 and he made a huge mistake when measuring last mirror power ,if you watch it you wil see in mirrors 1 and 2 he was holding power probe at the dial end which is ok ,however when he measured the last mirror he rested the power probe on a lump of steel,which would have acted like a heatsink drawing heat away from the dial,resulting in lower power readings,i made this mistake myself do i know how much this trows the readings out
