Hello group, I’m a new laser user and I’m having problems. I posted my issue in a few laser FB groups but haven’t found a solution yet. I went ahead and tried something quite simple today but it isn’t working out for me. See below my original issue and I’ll post pictures of today’s trial and error. Thank you in advance for any help I can get.
Hi everyone, I am new to lasers and Lightburn. Today was my first day experimenting with engraving (wood), and the biggest issue for me right now is my origin keeps moving. I will click the origin button to know where to set my wood, and it will go to the same location maybe 5 times in a row, then suddenly it will choose somewhere else as the origin. Sometimes it has been in the bottom left corner (and that’s what I set it as in the software), but sometimes it will end up somewhere else along the left hand side. I noticed a “set origin” in the software, so I brought the laser down the the bottom left corner and set it, but it still chose to go somewhere else when I clicked go to origin. Any thoughts as to what’s happening? I’m guessing that it has chosen between about 3 different places as origin today during about 15 jobs.
My controller is a cohesion 3D Smoothie.
My software is using absolute coords. and I never changed it between jobs. Both red and green squares are in bottom left of my software canvas. Another thing I thought about and forgot to mention, before using today, I also tried out the “frame” (I watched the first 3 lightburn videos on youtube), I wanted to test it out. It framed perfectly. My image was only approx 4" x 4" (although I’m using mm in the software). But later on when I noticed the origin moving, I tried the frame again, and although my image was now 2" x 2" for the current job I was testing, the frame went around quite a large area. And I’ve only ever had one image on my canvas. One more thing: I wanted to test the limits of my work space. When I saw that “origin” didn’t bring my laser down to the lower left as I was expecting, I used the “set laser position” icon in the left hand side menu (looks like google map location icon), I clicked into the upper right, and my laser wanted to go through the back of the machine. I stopped it quickly.
Today, I tried to burn a round of wood. It didn’t work out… I assume it is related to the other issue, but I am still new at this so I’m not sure.
I tried to post both a before and after picture in my post, but I don’t have that option yet being a new user… so here is the after pic.
