I hope someone can help. I’ve done a bit of digging through the forum and found all sorts of things to try but none seem to help.
I purchased a K40 from OMTech about a month or so ago. I ordered a Cohesion3D board and Lightburn at the same time. To be honest, I only test fired the laser to make sure it was working before I switched the boards out and began messing around in Lightburn.
My issue seems to be complete lack of power. I have cleaned the mirrors and the lense. I made sure the lense was the right way up(convex side up), I have double checked the alignment (all but perfect coming from OMTech), and reads tons of forum posts and videos trying to see what’s going on. I have tried paper, cardboard and 1/8th basswood so far. I have also tried each power level on the digital readout (I know, ammeter is coming) from 40 all the way up in increments of 10. In order to get any sort of image, I can’t go over a speed of 15-25 and the power has to be up well over 60. Cutting cardboard is a speed of 5 with a power of 100% and it takes 10+ passes to get a cut. These again are at readouts all over 40+. The cut is really crisp and not burnt, but it takes for ever. We’re talking about little 1 inch circles and squares. 4-5 mins per cut.
I have also tried the ramp test to verify where my focus point is. I’m at a complete loss folks.
Any thoughts would be helpful.
