Just got my 3d printed laser tube adjustable support brackets, after looking for over 12 months for something like these i almost wish my tube would blow so i can start using them.Not going to stuff around with current tube as it is aligned good and i do not stuff with things that are working ok unless it is preventive maintance.....

My k50 or sh 350 laser stopped firing,I still have my trusty k40 and will sit the k40 on top of the other laser cutter and wire up the 50 watt tube to the k50 to test if it fires ,if it does the powe're supply is faulty on the k50.has anyone wired a k40 40 watt power supply up to a k 50 50 watt machine?
. If it does not fire will wire up the k50 power supply to the 40 watt k40 laser tube,then if it doesn't fire it is something else .
I suspect the power supply as water temp and flow where ok and it just stopped firing 1/2 way through a small etching job
the last time tube was faulty I just lost most cutting power slowly over 3 days and not straight up,checked tube for cracks and seams ok . Try ed test button power supply and did not fire,amp meter i showing 0 ma, can not here any arcing

Suddenly lost most of my cutting power a week ago ,First time cutting at night in winter down here in Australia, suspect ed moisture forming on lens and mirrors as didn't have heating on and room temp was very low , now if it dew poin gets near temp in room I can monitor it on my new meter ..I miss my k40 having upgraded to a sh 350 or as some call it k50.

new Knife cutting bed- Magnetic
was using a pin bed for ages until i needed to cut small stuff so i made up a knife laser bed using hack saw blades ,fencing wire and clear plastic tube ,cost $20 and 15 minutes to make.Works better than i thought it would with no burn marks or glue on back of cut stuff.Also as made of steel magnets will stick to it>magnets also hold knife bed to old cutting table ,allowing very easy removal and cleaning
