Hi all , looking for some words of wisdom. I have a K40 which works great at the minute and I am starting to make me some money on ebay. I am currently building a bigger laser inspired by further fabrication on Youtube. I intend to cut mostly 3mm MDF.
I was thinking of buying a decent 40 watt tube for the new laser that would ultimately be replaced for an 80 watt when the coffers get recharged. I could use the new 40 watt as a spare for the K40. Is this a mad idea should I go straight for an 80 watt tube for the new laser and forget the K40. Thanks in advance. Alan Downpatrick NI
