Machine: _ Chinese 60 watt CO2. It came with an M2 Nano board.
Board: Cohesion 3D Laserboard
Problem/ Question: First, a little background, I am new to lasers. I have only been working with this one for a couple months. I never did use it with the original M2Nano. I was having problems, and was recommended the cohesion 3d laser board from someone in a FB group that got me set up with the board and with Lightburn. So when my laser was running and the head movement was sounding a little rough, I thought that was normal, I had nothing to compare it to. It was getting the job done, and doing a nice job, I wasn’t that concerned. But then it started jamming…
My laser head is “jamming” along the x-axis, but only if it’s working along the middle to right hand side of the work area. If I have a small job that is only using about 4" to 5" of the left hand side of the work area, it runs so smooth. Here is what I have done/discovered so far:
The laser head travels very smoothly when I home it from the opposite side of the work area or if I use the laser move buttons or use the “google maps” icon to move it around the board. It runs so smooth no matter where.
I tried burning items in 3 spots. Along the left side of the board, it runs very smooth. In the middle, it gets rough and sometimes skips/slides. Along the right hand side is very rough and definitely slips/jams. See my youtube video links below.
I tried changing what it was I was burning. On the right hand side where it is at its worse, I made a simple rectangle covering that area, and it scanned through the simple rectangle without issue. Text on the other hand, will “stick” and “jam” it up.
I have tried different speeds from 200mm/sec to 350mm/sec, and no change from above.
When I manually move the laser head back and forth along the x axis (and the y), it moves very smoothly.
I have tried changing the x axis acceleration to 1800 in the lightburn machine settings, it doesn’t help.
In case someone thinks this matters, I have aligned my mirrors, laser comes out in center, lens is cleaned.
Something I think is unrelated but I’ll put it here in case it’s important, I tried attaching a rotary tool (the cheapest kind that plugs right into the cohesion 3d) and between myself and my fb friend who also uses the same board and software, we couldn’t get it working properly.
Here are the settings my FB friend helped me with when setting up the board for the first time in lightburn:
Thank you so much in advance to anyone for your help, I have jobs here waiting, I’m losing money.
