I assume the colour orange or blue is no difference.īasically I want to get a k40 use it with lightburn and see how I get on and then either offload my diodes and buy a much larger C02 machine or stay with the diodes. I am also aware of grounding issues, length of tube ie 30 watt and not 40 watt and to avoid the digital models but I cant seem to finds the “D” models on ebay in the UK which seem to be the best of the bunch from reading articles, there is also a big price difference between Amazon and eBay european shops for a K40 when they are both based in europe and I am not sure why Amazon is more expensive, Markup? I was hoping for something a little cheaper and if I like the K40 then move up to a cohesion board later. I have a few diode lasers that I play with and I am thinking of picking up a K40 but I know these do not work with lightburn out of the box directly.Ĭan anybody in the forum point me in the direction of whats needed to make one work please on Lightburn apart from the Cohesion board which is a little out of my budget at the moment.
