So, I’ve spent some time lurking on here. I’ve been using an Eleksmaker A3 pro with Lightburn for some time now but have grown out of the 5w laser module that came with it. Just replaced it with a 15w beast. (To me anyway. It might as well be the Deathstar by comparison!) Got a few problems I was hoping the community would be able to help with.
- Using GRBL I was getting lines burned between shapes.
- Looking through the forums I have read that with the Grbl 0.9i firmware installed on this new laser module I should use GRBL-M3
- I’m now experiencing low powered burns and can’t identify why.
A lot of people experiencing similar problems talk about $30 on here but as you’ll see below, I don’t have that setting. You’ll see I’ve increased $120 AND $121 to 1500 as suggested in one thread but now improvement to the burn.
Anyone have any suggestions? Thanks in advance for your help.
