Please forgive me if this is in the wrong place. I am new to the forum and engraving.
I have a 50w co2 Chinese engraver. Blue and white, believe it is a omt. I have a roller style rotary. Both laser and rotar were bought used. Initially had issues with the rotar in which it would just sputter back and fourth, maybe rotating just 1/4 inch I each direction. I retired the connector and got it to work. I might still have some wires reversed as I have to flip the images I want to burn or they are backwards.
This is not the real issue I am having though.
I am burning on small long skinny objects (drum sticks) and having odd intermittent issues.
I realize a chuck would be better for my need but I can’t afford one right now so trying to get by with the roller style.
I am having an issue in which I can draw a rectangle that is the circumstance of stick and get the ends of the rectangle to touch, or essentially I believe I have the rotation test/steps/rotator settings correct.
However when I put text at one end of the rectangle the text looks like it’s climbing up hill at a 30 degree angle. I was pretty sure that the burned object was slipping on the rollers. I have found ways in which to add weight to the object I am burning on, and this seemed to have been a good temp solution.
However I am still getting odd random miss alignment of parts of my burns. By this I mean just a few letters will be out Of place or the entire burn will. Appear as if it’s shiftng and ends up a weird mess.
I have my rotator set to 2960 (trial and error), and measured the rollers with calipers. Using a Mac connected via Ethernet (directly, no WiFi or router, switches etc in the path).
I am using very low power, max in the low 20s and min power in the mid teens. And the speed I have been using 200 max down to below 100.
I am sure I am not providing enough details here, so please let me know what I can provide if anyone can help.
Also I will try to upload a picture.
Thanks in advance for any suggestions.
