Hey Jeffrey, I saw your post about your laser offsetting in the x axis slowly over time. My laser does the exact same thing.... which makes large engrave / cut jobs impossible. I feel like it is a stepper or voltage issue... but I could be wrong. Did you ever get it figured out? If you know anything, could you email me at: jondstallings@gmail.com Thank you so much. This problem has been terrorizing me for a year now! Sincerely, Jon
