Thank you for sharing. You both are great covering topics of areas I have not attempted. That is the things I love hearing. Thank you. Have a blessed day.
I do a lot of leather engraving with my K40 (has the Cohesion 3D board in it ) and am wondering how much current you are using when you are doing your engravings? I generally set mine to around 4-5 mA and then adjust my speed in lightburn to get the reults I want. Part of the reason you're losing a lot of the finer details is using to much power which burns a wider area around the beam. Going with less total power reduces this and gives you a really nice fine line.
I plan on testing the mA meter to see how much power it’s really using. It seems like a huge lose of power since going to lightburn and it is having issues cutting 3mm board now. I think it’s the board I am using.
@@KLRform well you are telling it to only use a fraction of the power you have set the machine to produce. I don't seem to find what you have the digital panel set to on your machine but on mine setting that to 50% gives me about 16mA which is the max you really want to use to avoid damage to your tube. So what I did to figure out digital panel settings vs actual mA reading is to start at 5% which gave me 3mA on my meter (which is just above the minimum current needed to fire the tube) and then went up 5% at a time on the digital panel until I was getting around 15% (16% in my case) and stopped there as I would not need to go any farther than that for use. When doing this all you need to do is have it turned on and with a scrap of some kind of material in the laser hit the test fire button briefly and see what the meter reads. Once you have this chart you can then pick an amperage that you want to use and set the digital panel to that setting. This will act as a hard current limit for the machine so you can'not go over the max amount you say. This is helpful when doing a gradient or power scale test for that particular current as lightburn will then scale the current from that setting to 0 as well as adjust the speeds you put in to show you what would work best. You'll find that most of the time you'll simply leave lightburn set to 100% power and adjust the current on the digital panel on the machine to find what you like best for a given material and speed. Hope this helps.
@@ropeany1 with the monport board you don’t use the digital panel at all anymore. So it should be going off of lightburn only. That’s why I plan to test when I can get the meter in and see what’s really going on.
@@pietpompiepompiepiet940 It depends on the control board. With the Cohesion 3D you have control in both places. With the monport board you can only control in lightburn. Our model does not have a dial
